Basic Principle of Machining and Arc Welding

ABSTRACT This project tittle ‘’basic principle of machining’’ deal with the operations on lathe, milling and some part of arc welding, turning, taper turning, threading, knurling and chamfering, while on milling machine spur Gears were cut, forming a hexagon shape and square shape were all done on milling machine. A simple component/part which contained all the above mention operation were produced in one work piece. In conclusion we are able to produce spurs gears, square thread, an...

Design and Development of a Hybrid Bicycle

This project involved the conversion of a conventional bicycle into an electric hybrid bicycle using a hub motor, battery, controller, throttle, and battery indicator. The selection of a flywheel-based regenerative mechanism was justified based on its superior energy storage capabilities. The challenges faced during the assembly, including bearing and clutch drive iterations, were overcome through the use of multiple bearings, metal casting, and welding. The implementation of an indirect...

Multi-function e-scarecrow (MFeSC)

Humans have taken the (scarecrow) as a protector for these crops from the birds. There are various different types and designs for the scarecrows around the world. In this project we will develop the traditional scarecrows to become electronic and do more than one function at the same time (Multi-functions mechanism) .The (MFESC) consists of several components, the most important of them is the sensor, which performs many functions, including sensing the presence of birds’ sounds, as well a...

Optimize the Operational Parameters through Simulation to Increase the Efficiency of Combined Cycle Power Plants

ABSTRACT  Electric power generation is one of the important factors for the development of peoples and can take an advantage of energy extraction technology of combined cycle in Sudan, which is highly effective in the States instead of remote power generation and combined cycle power plant also be economically feasible for use in sugar refineries in Sudan. . The purpose of this study is to find the maximum efficiency and minimum cost of power generation in combined cycle power plant by simul...

Design Analysis of HCCI Engine Piston

The piston is a heart of the engine and its working condition is the most exceedingly bad one of the key parts of the engine in the workplace. A piston is a segment of responding piston, responding pumps, gas compressors and pneumatic chambers, among other comparative systems. It is the moving part that is contained by a barrel and is made gas-tight by piston rings. In a piston, its motivation is to exchange force from growing gas in the barrel to the crankshaft through a piston bar and addit...

Energy and Exergy Analysis of Boiler Systems

ABSTRACT  In this work, the results of the analysis of the NBC boiler plant using energetic and exergetic methods are presented. The main aim of this study is to investigate the effects of boiler rotary burner cup speed, oil nozzle size, excess air and fuel types on its performance and emissions with a view to identifying and quantifying components having greatest losses of energy and exergy efficiencies. Optimization of the boiler operating system is also carried out. The specific objective...

Exergetic Efficiency of Passive Solar Air Heater with Phase Change Energy Storage Material

ABSTRACT  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 analysis, which is based on the second law of thermodynamics, and energy analysis, which is based on first law, was applied to improve system efficiency. M...

Fracture Mechanics of Glass Fibre Reinforced Polyester Composites (Gfrp) Subjected to Impact Load

ABSTRACT 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 impact and Linear Elastic Fracture Mechanics (LEFM) test procedures, to study the stress distribution around crack tip and zone. Plies of randomly...

Use of Finite Time Thermodynamic Simulation of Performance of an Otto Cycle with Variable Specific Heats of Working Fluid

Abstract  A finite time thermodynamic modelling and simulation of irreversible Otto cycle engines has been developed taking into account the variability of specific heats for working fluid due to temperature variation. The effect of three different parameters on the engine was discussed, which are: the internal irreversibility, the heat losses and the friction losses. A program was developed by using MATLAB software to perform the necessary calculations of thermodynamic model. According to t...

Effect of Delay Period on Performance of Compression Engine Running on Jatropha Fuel

Abstract Jatropha Biodiesel was tested in a single cylinder direct-injection, water cooled diesel engine to investigate the operational parameters of a small capacity diesel engine under five engine loads, constant speed test. The jatropha oil is used as a non edible oil to produce the biodiesel. The investigated blends were B0, B25, B50, B75 and B100, where (B#) denotes bio-diesel fuel volume percentage in diesel oil. The jatropha biodiesel was prepared locally in Sudan, specifications of wh...

Design and Construction of a Machine for the Production of Pulverized Coal-Rice Husk Briquettes

ABSTRACT The first part was the design and construction of a machine model using wood and the second part w pulverized coal-rice husk briquettes. The dt find the different loads due to shear stress on varlous parts or the nlachlne as the materials flow during consolidation. The loads obtained were used to dimension gears, shafts and pulleys that form the power transmission system of the machine. The machine was then drawn to produce a detail dimensional model in software form using AutoCAD. A...

Optimum Buckling Response Model of Grp Composites

ABSTRACT 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 limit and critical strain of composites were evaluated from compression tests results. It was found that the compressive strength of all the samples is...
