About 45 years (1970 to 2015) dataset was obtained from the Central Bank of Nigeria (CBN), the National Bureau of Statistics (NBS) and other relevant organizations. The data includes population, rainfall, electricity connectivity and temperature which are the explanatory variables. Matlab was used along with the dataset to train and evaluate the ANFIS model which was then used to forecast the industrial power consumption in Nigeria for the years 2016 to 2020.The prediction performance of the ANFIS model was compared to those of Autoregressive Moving Average model and Moving Average model. From the result obtained, ANFIS gave R-square value of 0.9977 (99.77%), SSE value of 395.3674 and RMSE value of 2.9641. The regression coefficient of 99.77% shows that about 99.77% of the variations in the industrial power consumption in Nigeria for the years 1970 to 2015 are explained by the selected explanatory variables. The forecast result showed that the Nigerian industrial power consumption would be about 374.7 MW at the end of 2020 which is about 73.1% increase from the industrial power consumption in 2015. As such, based on the industrial power consumption in 2015, over 73% increment in power supply to the industrial sector will be required to satisfy the industrial sector's power demand in 2020.","PeriodicalId":415209,"journal":{"name":"Advances in Energy and Power","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124396376","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}

Copper square duct was used to heat the air flow inside the duct. Various improvements have been investigated inside and outside the duct to increase the efficiency of heating. Analysis software has been used to simulate all models under investigation. Results show that there is a good agreement between experimental and numerical results and this agreement increases as air velocity increases. The average percentage error for air inside the duct at a velocity of air 1 m/s, 3 m/s and 5 m/s is 8%, 16.5% and 5% respectively. A metal foam has been used to increase the thermal conductivity outside the duct. Also the results depict that the temperature gain for air velocity of 1, 3 and 5 m/s enhanced by about 8, 8.4 and 15.8 %, respectively. Metal foam has also been used outside the duct with both granular hollow sphere duct and vertical cylinders to increase the conduction effect. The enhancement in heat transfer for air velocity of 1, 3 and 5 m/s is found to be 29%, 34% and 35.7 % respectively for this case. Paraffin wax has been also used as a thermal storage media for enhancing the time of thermal discharge. The granular duct, with cylinders and foam, has been found as the best thermal response model (among all models under investigation). A new Nusselt number correlation equation has been developed for the best thermal response model that was found in this work.","PeriodicalId":415209,"journal":{"name":"Advances in Energy and Power","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133275687","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}

There is global increase in demand of energy and it will continue to increase due to immoderate energy consumption. Today there is global fear of energy crisis as world primary demand of energy is expected to rise about 1.7 percent annually in next twenty years. South Asia is expected to give largest share for increase in global energy demand. Pakistan being a developing state is facing acute energy crisis that has hampered the socio-economic development. The energy crisis of Pakistan and its spillover effects on efficiency of other sectors especially economic sector has created serious issues in Pakistan for the last two decades. The overreliance on imported energy resources to satisfy the demand and less emphasis on the development of domestic energy resources is deteriorating the socio-economic conditions of country. There are two major sources of energy being used in Pakistan, renewable and non-renewable sources. In Pakistan, there has been more focus on non-renewable sources of energy which are largely acquired through imports of oil to satisfy the increasing demand. The state Energy policy has somehow has not able to match with the increasing energy demand and therefore citizens angered by frequent power outages demonstrate to protests and riots. Thus, this article, accentuate on the need of the utilization of the indigenous resources of energy to fulfill the energy need and to eradicate the acute crisis of energy. this research will also assess the issues in Power policy and Power sector institutions of Pakistan.","PeriodicalId":415209,"journal":{"name":"Advances in Energy and Power","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126943132","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}
