Biogas production from cassava waste
(Trans Tech, Switzerland, 2008-04-15)Anaerobic digestion is being taken seriously because of increasing concerns about the environmental hazards of wastes. The production of biogas, as an alternative source of energy was investigated in a designed and fabricated ... -
Temperature variation on the heated base of a solid substrate cooled with different type of heat sinks
(HEFAT, 2014-07)Three-dimensional numerical studies were carried out to investigate forced convection heat transfer and fluid flow in a solid substrate cooled using different types of micro heat sinks. The objective of this study is to ... -
Numerical optimization of forced convection of wall thickness of heated plates cooled using alumina-water nanofluid
(Begel House Inc., 2018-08)This paper applied constructal theory and design to present the numerical optimisation of forced convection of a rectangular plate placed between a heat source and a cooling fluid (Al2O3-Water) driven by forced convection ... -
Numerical investigation into two-layered microchannel with varying axial length and temperature-dependent fluid properties
(American Society of Mechanical Engineers, 2015-11)This study numerically investigates the thermal performance of a two-layered microchannel heat sink with varying axial length, varying solid substrate aspect ratio (ratio of height to width of the silicon solid substrate) ... -
Comparison between the thermal performance of single and two-layer microchannels inserted with micro pin fins
(Begel House Inc., 2014-08)This paper presents a three-dimensional numerical study of steady, laminar, incompressible flow and forced convection heat transfer through a two-layer rectangular microchannel heat sink inserted with pin fins. The objective ... -
Geometric optimisation of multi-layered microchannel heat sink with different flow arrangements
(Begel House Inc., 2014-08)This paper presents the use of the constructal design technique to optimise the geometry of a multilayered microchannel heat sink. The objective of this numerical investigation was to minimise the peak temperature of the ... -
Evaluation of some Non-Edible Vegetable Oils as Lubricants for Conventional and Non-Conventional Metal Forming Processes
(ESAFORM, 2019)The current study focuses on evaluation of the suitability of some non-edible vegetable-based oils as lubricants for conventional metal forming operations in general and non-conventional processes such as severe plastic ... -
Quality Of Physical Facilities And Human Resources For Engineering Education In Africa.
(2011-09)This paper assesses the quality of the facilities and resources for the training of engineers in some countries in Africa. The facilities are classified into internal and external. The internal facilities and resources are ... -
Implementation of Road Maintenance Works in Nigeria, using Labour- based Methods and Technology’
(1996-12-07)Roads form an integral part of our lives and provide means of safe and economic transport of goods and people for various purposes. Presently, majority of our roads both in rural areas and urban centre are in a deplorable ...
