CFD investigation of mesh, boundary condition and location, and the effect of turbulence models on the turbulent separated flow over a forward-backward-facing step. A numerical model was set up to replicate and compare with the model in the literature. The Reynolds number, Re, is 1.7E 5 based on step height 50 mm and obstacle length L = 10H. The… Continue Reading
A vehicle such as a large truck Can generate electricity for operating a hybrid engine or recharging batteries by use of an electricity generating driveshaft. The electricity generating driveshaft is comprised of a magnetized driveshaft which acts as a rotor, and a series of copper wire coils surrounding the magnetized driveshaft which… Continue Reading
Groundnut shelling machine was designed and fabricated at the department of Mechanical Engineering, institute of Technology, Kwara State Polytechnic Ilorin aimed at increasing shelling/decorticating efficiency and eliminating drudgery associated with the traditional method of -shelling groundnut and other developed method such as pedal… Continue Reading
An experimental evaluation of the performance of a charcoal stove designed to reduce human labour and health hazards associated with frying in open fire was carried out. The channel- type metallic stove was lagged with 2.54 mm thick glass wool. The charcoal grate is 160 mm from the floor and has 44 holes of 12 mm diameter each to serve as… Continue Reading
Relevant literature for the modeling and analysis of failure of GRP composites were reviewed. Samples of GRP composites were prepared by hand-lay up. Composites samples were subjected to compressive tests using a tensometer. Mechanical characteristics, such as modulus of elasticity; compressive strength, proportionality limit, elastic… Continue Reading
Glass mat reinforcement, which can be easily shattered, is widely used across the world in military, automobile, civil, railway and electronic engineering among others. This research investigated the fracture mechanics of reinforced polyester composites on exposure to sudden impact force, using experimental and analytical methods based on… Continue Reading
Energy and exergy analysis of solar air heater with phase change material energy storage is considered in this research work. Energy and exergy models for component systems like flat plate solar collector and phase change material in one-dimensional heat conduction in a cylindrical pipe, for storing periods were obtained. Exergy… Continue Reading
The effects of particle size and particle size distributions of three clay samples, on their modulus of rupture were studied. The three clay samples were collected from natural clay deposits at Nsu; Ohiya- Umuahia; and Awo-Omamma all in south eastern Nigeria. The particle size … Continue Reading

Electrochemical capacitors (ECs) or Super capacitors (SCs) are energy saving devices which have excellent properties that include high power density, long cycle life, low temperature sensitivity and low maintenance cost. However, these devices have lower energy densities than conventional batteries. To improve on its energy density, SnO2… Continue Reading
Equal channel angular pressing (ECAP) has over the years been used as a severe plastic deformation method to refine the grains and improve the strength of various metals. Even though this has been largely successful, research over the years has tried to increase the amount of strain induced in the materials used during this process so as… Continue Reading
This work investigates the optical properties of glass prepared using Otamiri Silica sand mixed with analytical grade oxides as a function of their composition. Three batches were prepared with Phosphorus as the main variable of the SiO2-Na2OB2O3-CaO-ZnO glass system. The glass was melted in a ceramic crucible with a lid and the glasses… Continue Reading
Abstract This research work examined the role of informal Sector in employment generation in Ilorin, kwara state Nigeria. The study made use of primary data obtained from 100 respondents from Ilorin West Local Government in kwara state through the copies of questionnaire administered. The data collected… Continue Reading
v ABSTRACT The project evaluates the effectiveness of quality control in Dangote Cement PLC, Ibese Ogun State, Nigeria. Limestone, shale and laterite samples were from the mines to determine their right grade as well as their mixing proportion. Also samples were taken from kiln feed and the final stage of… Continue Reading

Since early 1995 when pressure was mounted on the Raw Materials Research and development council in Nigeria, with a view to sourcing wire, flux and binder locally, little or no success has been recorded. As at 1998,allthe raw materials including core wire for electrode manufacture in Nigeria were still being imported. The aim of this… Continue Reading
The study was carried out to determine the effect of suggestopedia instructional technique on academic achievement, interest and retention of metalwork students of technical colleges. Six research questions were answered while nine null hypotheses formulated were tested at a 0.05 level of significance. The study adopted a… Continue Reading
This paper presents the operation of centrifugal pumps as turbines for micro hydropower application. Block diagrams are used to present components required from intake chamber to hydropower plant and their electrical energy mechanism for micro hydropower system. A comparison of operational parameters of pump as turbine and conventional… Continue Reading
Solar collectors mainly produced from poly-crystalline (P-Si) and micro-crystalline silicon (µ-Si) are in high demand in Nigeria due to persistent power challenges. The silicon are mostly imported and µ-Si is preferable due to its low cost. The µ-Si is extracted from Rice Husk (RH). However, the procedure of setting its optimal process… Continue Reading
This study developed computer software with the capacity to provide a generalized solution to queuing problems involving laborious, time consuming and complex mathematical approach of evaluating the performance measures of queuing systems when it was applied in the analysis of the six (6) fundamental performance measures of thirty (30)… Continue Reading
In recent years the entire world is a warring about energy resources limitation, specifically Sudan country confronts critical crises in fossil fuel resources and yet more of electricity energy producing from fired thermal power plants. One from these plants Garri”2” combined cycle producing about 180MW. Exergy analysis in the light… Continue Reading
The main aim of any electric power supply in the world is to provide uninterrupted power supply at all times to all its consumers. Although in developing countries, the electric power generated to meet the demands of the growing consumers of electricity is insufficient hence instability and outage. Power instability or… Continue Reading
Induction machine account for about 60percent of the electrical consumption in industrial countries; hence a huge energy savings could be achieved by even a small increment in the machine efficiency. Improving the designs of induction machines requires accurate quantification of the machine losses. A significant portion of the losses in… Continue Reading
