In the present study, a downdraft gasifier is used to gasify both raw and torrefied palm kernel shell (PKS). The properties of the palm kernel shells were characterised prior to gasification. Torrefaction of PKS was performed at the maximum temperature of 400 oC. Torrefied PKS shows lower moisture content by 4.8% as compared to raw kernel shell. Gasification of the feedstock showed that torrefied PKS produced higher amount of reactive syngas components, notably 16.4% CO and 9.25% H2 (by volume) than its raw counterpart. The total lower heating value of the syngas produced by torrefied PKS is 7.2 MJ/kg higher than that of raw PKS. Comparison of the temperature profiles within the gasifier for torrefied and raw PKS show distinct differences, with the temperature of the oxidation zone for raw and torrefied PKS being 1115oC and 1138oC at the equivalence ratio of 0.41 and 0.30, respectively. Although both feedstock show high potential for synthesis gas production, torrefied PKS produces syngas of higher LHV.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115166049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pakistan, having ample amount of water resources, is suffering from acute energy crisis these days. Currently it is facing a power shortage of 4000–9000 MW depending on the varying power demand due to severity of weather conditions. The shortage is managed by load shedding of up to 18 hours in some parts of the country. This power outage makes necessary services like health, education and industry difficult to manage. COMSATS being one of the prestigious higher education institutions of Pakistan is expanding day by day and a new campus is under construction at Dhamtaur (about five kilometers from the old Mirpur campus). This article discusses the hydropower potential of Dor River that runs near these campuses and its development as microgrid hydropower project for off grid use at both COMSATS campuses. The study concludes that both these campuses will collectively utilize almost two thirds of the produced energy. The payback period of the project is less than fifteen years. The results of this study encourage the policy makers to think on developing such projects, specifically for education and health purposes where load shedding may cause irreversible damages.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127066710","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the investigation requires specialized facilities and manufacturing of scaled models which are costly in both time and money. This paper outlines the development of Numerical Wave Tank (NWT) for the Universiti Teknologi PETRONAS (UTP) wave basin as a virtual simulation tool for regular waves propagation using an open-source licensing numerical model waves2FOAM which inherits its basic structure from OpenFOAM in solving the famous Reynolds Averaged Navier Stokes (RANS) equation. The model validation was performed by correlating the simulated NWT wave properties with the actual waves generated by physical experiment under similar input condition and a 1:1 scale. Mesh fineness study was also performed to investigate wave height convergence with varying mesh sizes, which leads to the optimal mesh size with respect to computational time and reliability. It is shown that good correlation was achieved between the wave properties simulated by OpenFOAM and physical experiments. This study demonstrates the viability of developing a reliable virtual wave tank with open source tools which is anticipated to complement its real counterpart in future studies concerning fluid dynamics and fluid-structure interaction.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122940181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gearless pump has a fluid chamber which features a single-lobed limacon (planar) geometry, based on the geometric model used in defining the Wankel rotor and chamber. The simulation study predicts that the mechanical efficiency of the pump varies linearly with the head coefficient; within the onset of internal leakage, the capacity coefficient is not sensitive to pump efficiency. Although the valveless positive displacement pump results in a low efficiency (less than 30%) — pump flow-rate decreasing appreciably at the onset of an internal leakage — the flow field reveals threedimensional vortices even in the laminar regime, including Taylor-like counter-rotating vortex pairs, indicating that these pumps may be exploited for microfluidic mixing applications. The preliminary design and prototyping stage involved considerations for the fluid chamber, rotor, drive shaft, the motor and the flow circuit. This led to three main designs, namely the single-stage (single-tier rotor) pump/mixer, the N- stage pump/mixer (where we have investigated the case of N = 2) and the single-stage (two-tier rotor) pump/mixer. Key challenges and prospects of these prototypes are discussed. Given that the planar geometry design described is the minimum required to keep a clean tank bottom during mixing, such a rotary pump/mixer may find applications in biofuel processing, e.g. biodiesel.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127292656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Activated carbon (AC) is considered as the best candidate to accomplish this goal. Core objective of this work is to enhance capability of activated carbon to adsorb gases of low molecular weight and high volatility by impregnating specific metals on the surface of activated carbon using various salts in different medium i.e. basic and neutral. Imbibing limit is used as the method of impregnation and shaking time is nearly one minute after introducing few drops of impregnating solution. Final form of impregnant is either oxide or sulphate while oxide is the desirable form because in this form of impregnant, the sample needs not to be heated at elevated temperatures to remove volatiles or calciners. Mass variations of samples with rise in temperature give clue that at 160 °C calciners are removed from the surface of activated carbon. BET surface area analysis gives information that after impregnation there is no considerable change in the value of available pores of activated carbon, which is contrary to previous research. AAS results confirm that metal doping in alkaline medium has imparted a comparatively higher concentration of zinc metal to the AC surface as compared to impregnation in neutral medium. In addition, optimized concentration of zinc oxide in alkaline (ammonia solution) medium was 1.17 M of zinc oxide and in neutral medium it is 0.4 M. Optimized temperature to heat the sample to remove volatiles is 160 °C. Peaks of zinc oxide are not prominent at low temperature, nevertheless when temperature of sample is raised up to 450 °C, the peaks become prominent and the results match well with available literature.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129766310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study quantifies the effect of absorbed moisture on the strength, stiffness, and energy properties of adhesive bonded joints. For this purpose, moisture absorption characteristics of structural adhesive joints (Araldite2015) with different thicknesses (0.5, 1.0, and 1.5 mm) are established under accelerated aging conditions (deionized water at 60 oC). A thickness-dependent two-phase moisture absorption model was used to characterize moisture absorption of the adhesive joints. Results show that the moisture absorption of the adhesive joints is governed by capillary action. Adhesive joint specimens with aluminum 6061 adherents and 0.5 mm-thick Araldite 2015 adhesive compound are subjected to dry and 0.2 % moisture content. The specimens are tested in shear and tension under rate-dependent loading condition of 5, 50, 250, and 500 mm/min. The variations in the properties which are strength, stiffness and strain energy density are calculated from the rate- dependent load response. The properties of dry adhesive joint significantly increases with the test speed, while minor increase in similar effect on stiffness properties for ageing adhesive joints. Meanwhile, for the failure modes, mixed-mode failure is dominating at all loadings directions.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122320639","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
