This paper described a combined experimental-computational approach to determine the properties and material parameters for the fatigue model. The approach is demonstrated for the cyclic shear loading. For this purpose, carbon fiber-reinforced polymer (CFRP) composite laminate beam specimens ([0]8), each with a pre-cracked interface is tested under 3-point bending setup. Interfacial fatigue damage is introduced by subjecting the specimens to fluctuating load (ΔP = 75 N, R = 0.25) and varying numbers of accumulated cycles (50, 100 and 200 kcycles). Subsequent quasistatic test to catastrophic failure establishes the characteristic residual strength responses of the damaged specimen. A complementary validated finite element (FE) simulation of the load-displacement response establishes the stress and strain states at the damaged interface. These internal local variables at the crack front are employed to determine the fatigue-related damage model parameters. The resulting interfacial shear strength, penalty stiffness and critical shear energy release rate are found to vary non-linearly with the accumulated number of load cycles.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"74 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":"123117779","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}

Fears of the non-renewable resources depletion aside, fossil fuels have also been proven to be one of the main causes of global warming. Whilst in search of alternative fuels worldwide, biodiesel has emerged as one of the most viable candidates. This study aims to provide an overview on the feasibility of biodiesel to supplant fossil diesel through detailed analysis of feedstock readiness and economic viabilities of the implementations of three generations of biodiesel, i.e. edible, non-edible and algae-based biodiesel. In this paper, the global total production of biodiesel of 176 countries is calculated. At 85 billion litres, the first and second generation biodiesel production has the potential to exceed its current production by three times. The profitability of the biodiesel production relies heavily on the crude oil price. When the crude oil price peaked at 133.9 USD/bbl, 74% of the global potential biodiesel production can be made profitably, contributing 135.45 GW into the renewable energy mix. With business as usual scenario, edible oil biodiesel will remain to be the dominant category of feedstock. Nonetheless, 15 countries are able to replace portions of diesel consumption with second generation non-edible biodiesel, with two being able to entirely supplant fossil diesel with it The implementation of third generation algae-based biodiesel can save up to 93% of arable land. In all, biodiesel represents a great alternative to the unsustainable fossil diesel usage and contributes to the renewable energy mix.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"108 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":"128081567","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}

Unfortunately in Pakistan the power sector is facing severe energy crisis due to shortage in power generation and increase in load demand at the rate of about 10% each year. One of the main reasons is greater dependency on traditional energy sources like fossil fuels and hydroelectricity. The rural electrification is a big challenge in Baluchistan province due to dispersed load and high distance location of grids from the load centers. Rural electrification in most developing countries is now carried out with available renewable resources potential. In Baluchistan both solar and wind energy is available in abundant. In this research work both resources with other option of local coal and LPG (non-renewable) is presented to electrify the remote areas. The work illustrates the overview of power sector, total available renewable energy sources and optimal utilization of these forces at remote regions. The final analysis provides the potential based renewable energy implementation in rural areas of province.","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":"121551311","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}

At low molar ratios, residual NO that escapes from the high temperature urea SNCR (900°C to 1200°C) process, may be oxidized to NO2 by compounds containing (−OH) group injected at low temperature secondary stage and this NO2 can then be removed by scrubbing. In present study, low temperature (500°C to 800°C) gas phase oxidation of NO using compounds containing (OH) group such as methanol is initially investigated. Subsequently, experiments were performed by combining this low temperature gas phase oxidation at the back end of high temperature urea SNCR in a two-stage experimental setup. The results of initial (−OH) additive injections in flue gases revealed that the additive investigated has an optimum temperature window for efficient NO to NO2 conversion which ranges from 600 to 750°C. The optimum reaction time within this temperature window was found to be between 0.4 to 0.6 seconds. Investigations with two-stage experimental setup have shown that significant improvement in primary stage NOx reduction efficiency can be achieved by low temperature injection of additives in the second stage. A 50% to 150% increase in the overall removal was achieved using methanol solution in second stage with urea in primary stage. Through a selection of primary and secondary additives, with due considerations to their optimum temperature ranges, the efficiency could be increased to 97%. Low temperature NO removal, increase in efficiency and the low optimum amount of secondary additives (M=1.0) reflected the attractive features of two-stage NO removal technique.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"11 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":"125043523","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}

A flow phenomena termed as phase maldistribution have caused oil and gas industries to use T-junctions as partial multiphase separators. This is because, a T-junction can reduce the load on main separators by partly separating the gas from the multiphase flow coming from an oil well. From the previously published research, it was found that liquid phase superficial velocity have an inverse relationship with liquid carryover. However, to the best of author's knowledge, all of these investigations were focused on T- junctions with diameter ratios between 1 and 0.2. Likewise, most of these studies were performed on fully horizontal T-junctions. Previous literature also states that decreasing the diameter ratio increases the phase separation performance of a T-junction. However, a couple of sources reported that in very small diameter ratio T-junctions, liquid carryover becomes very sensitive to side arm extraction rates. This ultimately cause liquid carryover to suddenly increase at high extraction rates. Therefore, a numerical study is carried out in order to understand the effect of liquid superficial velocity on liquid carryover in a 0.167 diameter ratio T-junction having a vertically upward side. For this study, simulations were performed on 1 and 0.167 diameter ratio T- junctions under air-water stratified flow conditions. Results from 1 diameter ratio T-junctions were used to validate present model by comparing it with previously reported experimental data. The results obtained from 0.167 diameter ratio T-junction depicts that higher the liquid phase velocity, less will be the liquid carryover. However, liquid carryover is relatively quite large in 0.167 diameter ratio T-junction as compare to 1 diameter ratio T- junction under stratified flow conditions.","PeriodicalId":336020,"journal":{"name":"2017 3rd International Conference on Power Generation Systems and Renewable Energy Technologies (PGSRET)","volume":"65 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":"131719510","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 original Pareto frontier between cost and safety function is determined by implementing multi-objective optimization using genetic algorithm. The cost function of the ventilation and air conditioning system was developed based on the present value of the total cost. The safety function of this system was based on contaminant concentration levels which were obtained by using air change rates, negative pressure, and temperature parameters.
