Although a number of correlations for convective heat transfer in engine environments have been implemented in simulations with some accuracy, reliable correlations for the radiant heat transfer are yet to be developed. Most radiant heat transfer correlations are configuration-dependent and fail to accommodate important physical aspects of the radiant heat transfer process in diesel engines. The development of reliable radiation heat transfer correlations requires reliable data. The two-colour method for radiation measurement has provided valuable insight into the combustion process inside direct-injection compression ignition engine. The two-colour method is a popular approach because it is cost effective and simple approach that can provide time-resolved data. The objective of this paper is to present a review of radiation heat transfer measurement in the diesel engine environment using the principles of the two-colour method. The theory, approach, issues and complications associated with the two-colour method are discussed.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126612731","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 three-dimensional steady, laminar flow and heat transfer governing equations are solved using the finite volume method. It is found that the values of Poiseuille number and friction factor depend greatly on different geometrical parameters. It is also inferred that the heat sink having the smallest hydraulic diameter for each type of shapes under consideration has better performance among the other heat sinks studied. The values of Poiseuille number and friction factor increase with the increase of width-height ratio (Wc/Hc) for rectangular microchannels. For trapezoidal microchannels, the Poiseuille number and friction factor increase with the increase of bottom-to-top width ratio (b/a), increase with the decrease of height-to-top width ratio (h/a), increase with the decrease of length-to-hydraulic diameter ratio (L/Dh). While for triangular microchannels, the Poiseuille number and friction factor increase with the increase of its tip angle (β).

The LPG was supplied from a LPG tank which was purchased from a local gas distributor. The primary content of LPG is 60% propane and 40% butane. The four-stroke spark ignition engine has an engine capacity of 183cc and a compression ratio of 6.3∶1, and it was coupled to a 5kW eddy current dynamometer for performance measurement. A 5-gas Non-Dispersive Infra-Red (NDIR) analyzer was used for CO, CO2, unburnt HC, and NOx measurement. Two sets of experimental data obtained were analyzed; (i) 100% gasoline, and (ii) 5%, 10%, and 20% of LPG in gasoline. It was found that in general, the engine's power output and torque suffer a drop in performance compared to 100% gasoline fueled engine, when tests were evaluated with 5%, 10%, and 20% LPG in gasoline. However, the brake specific fuel consumption, BSFC shows an improvement with LPG as a fuel replacement. The concentration levels of CO, CO2, unburnt HC, and NOx recorded are found to be lower than the gasoline fueled engine.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134080149","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}

Alloying with other elements prevents the development of oxide layer by introducing localized galvanic cells. Different aluminum alloys exhibit different electrochemical behavior. The scope of the project was to study the electrochemical behavior of different chemical composition of aluminum alloys in natural seawater. The significance of understanding the corrosion behavior of aluminum alloys is essential in the fabrication of sacrificial anodes to be used in cathodic protection in corrosion control. Aluminum alloys were fabricated using alloying elements Zn, Sn, Mg, Cu, Fe, and Si. Divided into two groups, samples of aluminum alloys in Group 1 contain same weight percent of Zn, and different weight percent of Sn. Aluminum alloy samples in Group 2 contains same weight percent of Mg, Cu, Fe and Si with different weight percent of Sn. The samples were then subjected to corrosion behavior experimentation which includes Tafel plot, corrosion potential and potentiodynamic scan. It was found that alloying with Mg, Cu, Fe, and Si instead of alloying only with Zn and Sn further increases the negative potential, the density of particle distribution and further reduces the corrosion rate of aluminum alloys. The activeness of aluminum alloys also increases when alloyed with Zn, Sn, Mg, Cu, Fe, and Si.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115159438","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}

To date Malaysia had utilized this potential in the range of large and mini hydropower but not in the micro hydro range. Micro hydro refers to power generation in the range of 5kW to 100kW. Micro hydro can provide alternative renewable energy sources especially in areas with small rivers or streams flowing. In identifying the micro hydro potential sites, reconnaissance studies is normally conducted. It is a preliminary study to identify micro hydropower potential. This paper presents the results of reconnaissance studies carried out to identify the micro hydro potential in West Malaysia. The reconnaissance studies were conducted with data from the Department of Survey and Mapping Malaysia, (JUPEM) and Metrological Department Malaysia. All the identified streams are located in areas which are accessible and/or showed evidence of settlements. Only streams with high head i.e. above 50m were considered in this study. From the reconnaissance studies, a total of 109 sites having micro hydro potential of about 20.4MW were identified. However, the energy demand for micro hydro was found not significant in West Malaysia as most areas are electrified. Still, micro hydro generation may serve as alternative renewable energy source in future amid rising electricity cost.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125160915","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}

Short duration wind tunnels such as shock tunnels and gun tunnels rely on a transient compression process and are likely to generate significant turbulent fluctuations in the nozzle reservoir region. In the present study, the magnitude of likely stagnation temperature fluctuations in two such facilities is inferred from incompressible temperature fluctuations data obtained by other workers. The friction velocity Reynolds numbers for the gun tunnel and shock tunnel cases considered presently were Reτ =31,579 and 24,975 respectively. The RMS stagnation temperature fluctuations, when averaged over the pipe flow diameter, are estimated to be 14.6 and 278 K for the gun tunnel and shock tunnel cases respectively. The estimated RMS value in the case of the gun tunnel is significantly larger than the experimental value previously measured on the centre line of the gun tunnel nozzle of 2.3 K. The difference observed between the inferred and measured temperature fluctuations in the gun tunnel case may be related to spatial variations in the temperature fluctuations. In the case of the shock tunnel, the magnitude of the fluctuations is demonstrated to be significant for supersonic combustion experiments. The present approach for estimating the magnitude temperature fluctuations should be refined, but more detailed measurements of temperature fluctuations in such facilities are also required.","PeriodicalId":211736,"journal":{"name":"2009 3rd International Conference on Energy and Environment (ICEE)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130852076","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}
