As one of the fast growing developing nations, its world renowned infrastructures include the Petronas Twin Tower, SMART tunnel and Bakun hydro dam. A key component that enables this growth is its secure, affordable and reliable electricity sector. Eventhough the initial electricity facilities here was constructed by the British during colonization, Malaysia then continue to nurture its development and reliability through her national policies to ensure that it continues to support her growth and prowess. The main national policy involving the electricity sector in Malaysia is the National Energy Policy. It was formulated in 1979 to ensure efficient, secure and environmentally sustainable supplies of energy including electricity. Later other policies were also formulated to address the arising issues and concerns on the energy sector. Among them are the National Depletion Policy, the Four Fuel Diversification Policy and the Fifth Fuel Policy. This paper reviews and discusses their implementation and various impacts on the electricity sector in Malaysia.","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":"132315452","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}

As these simulations are sensitive to user-defined empirical parameters, the main aim of this investigation is to obtain an adjusted set of model parameters in order to achieve realistic results with the current version of FLUENT. Validation of simulation results is based on matching parallel experimental data to gauge the accuracy and applicability of each sub-model used. A Lagrangian Discrete Phase Model is employed to simulate spray atomisation/breakup process. Wave model is used, and the corresponding breakup time constant value, B1 that equals to 20 produces the most accurate results. Other sub-models such as drop distortion and dynamic drag, spray wall impingement and wall film with rebounding sliding and break-up, two-way turbulence coupling, collision and coalescences are integrated to model the dynamics of fuel spray. RNG k-ε is best suited for RANS approach to capture in-cylinder turbulent flow condition. Non-premixed combustion model which adopts the PDF approach provides good prediction of the in-cylinder diesel combustion process. The rich flammability limit of 0.1 produces good agreement with the experimental data. Extended Zeldovich, Fenimore and Turbulence-Interaction are incorporated to model NOx generation. One-step Khan and Greeves model is used for soot formation and oxidation prediction. Both soot and NOx models are parametrically calibrated to give reasonable predictions of the experimental measurements.","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":"114126645","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}

Accurate determination of the pressure-volume-temperature (PVT) properties such as the bubble point pressure (Pb) and the oil formation volume factor (Bob) are important in the primary and subsequent development of an oil field. This paper proposes Support Vector Machines (SVMs) as a novel machine learning technique for predicting outputs in uncertain situations using the ɛ-Support Vector Regression (ɛ-SVR) method. The objective of this research is to investigate the capability of SVRs in modeling PVT properties of crude oil systems and solving existing Artificial Neural Network (ANN) drawbacks. Three datasets used for training and testing the SVR prediction model were collected from distinct published sources. The ɛ-SVR model incorporates four input features from the datasets: (1) solution gas-oil ratio, (2) reservoir temperature, (3) oil gravity and, (4) gas relative density. A comparative study is carried out to compare ɛ-SVR performance with ANNs, nonlinear regression, and different empirical correlation techniques. The results obtained reveal that the ɛ-SVR once successfully trained and optimized is more accurate, reliable, and outperforms the other existing approaches such as empirical correlation for estimating crude oil PVT properties.","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":"127940837","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}
