Efforts by the government to solve the energy crisis in the country over the years with the conventional methods of generating electricity has not yielded the desired result hence the need for alternative source of ...

A growing awareness of the educational benefits of the Internet has contributed to a sense of urgency among tertiary institutions worldwide to deploy it. However, with its many advantages also come the numerous challenges ...

This paper looks at the effect of road surface conditions on the maintenance profile of TRICYCLE mode of transportation in the suburb of Lagos Metropolis. Primary data such as purchase, maintenance and route/road ...

The supply of energy through sources that have been adjudged not to be amenable to cleanliness and supportive of emission control, which are also finite, necessitates the search for alternative sources of energy. This ...

Solar energy has always been one of the abundant renewable energies in Nigeria, and today there is a gap between its availability and utilization. This is underlined by the fact that the average sunshine hour per day ...

Triangular enclosures are typical configurations found in attic spaces of residential as well as industrial pitched-roof buildings. Previous studies on airflow within such spaces have focused on the laminar range. A numerical ...

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 ...

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 ...

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 ...

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) ...

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 ...

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 ...

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 ...

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 ...

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 ...
