Augmentation of Heat Transfer in a Trough Shaped Solar Collector Compared to Flat Plate Collector Using CFD
Abstract: Surface Enhancement plays a vital role in augmenting the thermal performance of flat plate collectors. In this paper, an attempt is made to explain in a comparative way the effect of surface geometry of solar flat plate collector having troughs with that of a normal collector. Flat plate collectors with and without troughs of dimensions 1 × 0.5 m is modelled in CATIA V5R19 and meshed using ANSYS ICEM CFD. …

The Thermal Physical Phenomenon of Some Native Wood Species in Nigeria
Abstract: The Determination of the thermal conductivity of some selected local wood species from measurement of necessary parameters required in its determination were performed using the Lee's disc method of measuring the thermal conductivity of a poor conductor in the form of a flat disc. Five hardwood species commonly patronized by timber contractors, builders, woodcarvers and cabinet-makers in Ile-Ife town, Nigeria were selected. The steady state method was employed in this …

Thermal Analysis of CaZrO3 Coated Diesel Engine Liner Using 3-D Finite Element Method
Abstract: Abstract Results, obtained from many research papers it has been observed that in internal combustion engine about one third of total fuel energy is converted into useful work, about one third of the total fuel energy goes with exhaust gases and about one third of total fuel energy transfer to the coolant in form of heat through the cylinder wall, piston, valve etc. According to second law of thermodynamics, exhaust …

On Suitability of Supercritical Carbon Dioxide As Heat Transfer Fluid in Flat Plate Solar Collector
Abstract: In the present article, carbon dioxide is proposed as a heat transfer fluid for flat-plate solar thermal collector. Energetic, exergetic and economic analyses of flat plate collector using supercritical CO2 have been done and compared with conventional fluid (water) as well as advanced fluid (nanofluids). Effects of zonal ambient temperature and incident solar radiation on collector efficiency, irreversibility, second law efficiency and collector size reduction are presented. Due to lower …

Exploration of Geothermal Energy from Abandoned Oil wells (A Case Study of Eleme, Porthacourt, River State, Nigeria)
Abstract: This project considers the basic technical aspects of power generations from some abandoned oil wells which involve the analysis of the data from the wells. The power capacity of the wells in the first category is determined primarily by the temperature of the produced water and conversion efficiency of the geothermal power plant. The factors that control the wellhead temperature of the produced fluid are: formation temperature, well depth, well …
