Electricity Generation Using Propeller Shaft

ABSTRACTA 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 acts as a stator in an electrical generator. As the magnetized driveshaft spins as a result of power from the hybrid engine, an electrical fi...

ENGINEERING CHARACTERIZATION OF OGBEKE CLAY DEPOSIT FOR INDUSTRIAL APPLICATIONS

The engineering characterization of Ogbeke clay deposit has been investigated with a view of finding its usefulness in furnace refractory production and home. The chemical composition analysis was carried out using Atomic Absorption Spectroscopy (AAS). The physical properties tests such as shrinkage, porosity, water absorption, modulus of rupture, refractoriness, moisture content, plasticity, cold crushing strength, thermal shock resistance and particles size analysis were carried out using i...

EFFECT OF MESH, BOUNDARY CONDITION AND TURBULENCE MODELS ON TURBULENT SEPERATED FLOW OVER A FORWARD-BACKWARD-FACING STEP

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 1.7E5  based on step height 50 mm and obstacle length L = 10H. The freestream velocity of air at the inlet is 50 m/s. The simulation was performed using the ANSYS software.

Numerical Investigation of Mesh Material Properties on Heat Convection and Conduction of a Vertical Impinging Round Jet onto a Horizontal Surface (Stationary and Moving)

Using Computational Fluid Dynamics (CFD), this paper investigates the effect of mesh material properties on the heat convection and conduction (fluid-solid interaction) of a vertical impinging round jet onto a stationary and moving horizontal surface, as well as the effect of conjugation in the solid domain. This paper is an excerpt from an assignment in Numerical Thermoflow that was completed in 2021 during my Bachelor of Science Honours in Applied Science Mechanics at the University ...

Operation and Maintenance of Steam Boiler

ABSTRACTThe steam boiler is to control specification problem, to illustrate how the evolving algebra approach to the specification and the verification of complex system can be exploited for a reliable and well-documented development of executable but formally inspectable and systematically modifiable code. A hierarch of stepwise defined abstract machine model in developed, the ground version of which can be checked for whether it faithfully reflects the informally given problem. The se...

Real Time School Bus Tracking System Using (Rfid)

ABSTRACTIn present time due to increase in number of kidnapping and road accident cases, parent always worry about their children.This paper proposes a SMS based solution to aid parent to track their children location in real time. The proposed system takes the advantage of the location services provided by module kit which carry by the child in their school bag. It allows parent to get their child location on a real time map by the geographical co-ordinates which send by module kit. I...

The Maintenance of Workshop Equipment

ABSTRACTMaintenance is the technical exercise that is usually carries out on machines to restore a component going to fail or failed component back to it design function in the machine. The role of maintenance in machine work shop can not be over emphasized, because without it, many causality that would have been recorded in a workshop would have been much, most especially in some machine workshop that deal with the use of hazardous chemical in their production process of materials. e.g petro...

Fabrication of Domestic Deep Freezer

ABSTRACTRefrigeration is term used to denote the maintenance of a body at a temperature lower than that of its surroundings. The applications of refrigeration are many and varied. In addition to the common applications of refrigerationin the manufacture of ice, in the preservation of foods, in air-conditioning filed, and in the creation of skating rinks, the refrigeration effect is also used in the presentation of blood plasma, in the low-temperature treatment of metals and in the lique...

Fabrication of Metal Panel Door

ABSTRACTSecurity of life and property cannot be over emphasized. Human beings need privacy in their various homes and offices which necessitate the need for doors among another security services. To has been a major challenges for the people to have door of high quality and that are also durable at affordable prices by an average Nigerian. This project was done purposely to fabricate a metal panel door of high quality capable of giving maximum securities to life and properties at afford...

Design and Fabrication of Domestic Deep Freezer

ABSTRACTThis project is on the design and fabrication of deep freezer for the preservation of items/products and making the items to cool. The project is able to develop a simple efficient economical and environmental friendly refrigeration system (A freezer) towards better technological advancement in Nigeria. This project modifies the existing refrigeration system with the use of R-600a which is ozone friendly, and non-contaminant like previous refrigerant of the hydrofluoric-carbon,...
