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...
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...
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...
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...
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...
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...
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...
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...
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...
ABSTRACT This research work is aimed at using the energy and exergy analysis with thermodynamic data to suggest improvements in the performance of steam and gas turbine power plants. In this regard, specific data from Egbin steam power plant and Geregu I gas turbine power plant were used for the analysis. In the analysis, scientific tools such as Engineering Equation Solver (EES) programme with built-in functions for most thermodynamic and transport properties was used to calculate the enthal...
ABSTRACT 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 air holes and provide passage for ashes, drilled in it. The charcoal bed is 230 mm from the bottom of the pot and the channel gap is 8mm. A 300 mm ...

Albeit most mature associations work their cycles at exceptionally low imperfections per million open doors, clients expect totally deformity free goad ucts. Thus, the brief location of interesting quality occasions has turned into an issue of fundamental significance and a chance for assembling organizations to push quality norms ahead. This article presents the educational experience ...
AI has as of late tracked down numerous applications in aviation and remote detecting. These applications range from predisposition rectification to recovery calculations, from code speed increase to identification of illness in crops. As a wide subfield of computerized reasoning, AI is worried about calculations and methods that permit PCs to "learn". The significant focal point of AI is to extricate data from information consequently by computational and measurable techniques. Over th...
