Respondents have selected using simple random sampling technique. The responses were entered and analyzed by using SPSS v11. The findin...
Abstract aerospace is one of the most developed science all over the world and it is not exclusive to the developed countries. In a country like Sudan with extended boundaries, huge internal resources never profiteered from this technology. There are numerous security problems represent some challenges. The main objective of this study is to design a small microsatellite structure to solve and control those types of problems. Microsatellite structure was modelled using SOLIDWORKS then the st...
ABSTRACT The performance of diesel engines is heavily influenced by their injection system design. In fact, the most notable advances achieved in diesel engines resulted directly from superior fuel injection system designs. While the main purpose of the system is to deliver fuel to the cylinders of a diesel engine, it is how that fuel is delivered that makes the difference in engine performance, emissions, and noise characteristics. The objective of the present work is to evaluate performanc...
ABSTRACT Cavitation is the appearance of vapor cavities inside an initially homogeneous liquid medium, occurs in very different situations. According to the flow configuration and the physical properties of the liquid, cavitation is the most commonly required one in all the researches on the pumps and flow systems but they are too hard to manipulate with the primary methods. In this research was study the effects of rotational speed (rpm); flow rate (Q); fluid temperature (T) and pressure (P...
Abstract Abrasive Water Jet Machining – (AWJM) become one of popular and growing processes among Advanced Machining Processes. It has high material flexibility and advantages of geometric, and ability to cut materials that are hard to machine using conventional technologies, it reduces the time necessary for secondary operations like programming, tool changing, or clamping. this allows a significant optimization of the overall manufacturing process chain. All these Advantages lead to (AWJM)...
Abstract The highway system of a developed country contains thousands center line kilometers of streets. Such systems consist of asphalt, concrete or composite streets ranging in condition, in recent years, several road network monitoring and maintenance programs have been established in order to monitor the on-going performance of the road network, to predict future road conditions and assess long term needs, to support investment planning and decision making, and to identify rehabilitation...
Abstract: Through centuries, the man try to optimize jobs, and reduce the costs. In transportations system, the compact one is more desirable. In this research the sand pneumatic conveying system, used in Garri-4 power plant CFB (Circulating Fluidized Bed) boiler, a problem of high rate erosion studied. And the research aiming to find optimum and reliable solution for it. Experimental test done by using sand-blasting machine to simulate and to test the proposed solution, which is the change ...
ABSTRACT A PLC is a digital computer used to automate electromechanical processes. PLC is frequently used when implementing automated control, which is an important part of many modern industries. This research is based on monitoring Level Temperature Pressure Flow and water cut of crude oil in the vessel by using ABB Programmable Logic Controller . Automatic control of crude oil in vessel can work continuously and can provide accurate quantity of crude in less time. In such process there is...
ABSTRACT The performance of Butan-1-ol (BTU) on the pitting corrosion inhibition of austenitic stainless steel (Type 304) in dilute sulphuric acid contaminated with recrystallized sodium chloride was investigated with the aid of potentiodynamic polarization technique. Corrosion potential, pitting potential, passivation potential, nucleation resistance, passivation range, passivation capacity measurements and potentiodynamic analysis were used to assess the pitting resistance characteristics ...
Abstract This research concerns with the energy resources in Sudan. It includes the steam plants, their unplanned outage problems. The study conducted on Dr. Sharief power station in Khartoum north. The research is studied the station problems occurring during the period (Jan 2011 to Dec 2015), the maintenance program procedure and management method description. Losses resulting from unplanned outage were calculated. The rest of maintenance was not calculated because there were no enough dat...
Abstract Diesel engine model simulation designed for four-stroke direct-injection diesel engine requires the use of advanced analysis to carry out of the direct-injection diesel engine model performance effect focuses on fuel nozzle multi holes geometries. The computational model simulation development was use the commercial computational fluid dynamics of GT-POWER 2016 software were specially development for internal combustion engines performance simulation. The research concentrated on th...
Abstract The objective of this research is focused on the vortex flow in Kaplan turbine runner - a tip vortex. CFD analysis was performed to predict the water flow inside the turbine for more diagnosing and investigation of the hydro power problem. On the basis of this analysis it is possible to estimate the existing and the intensity of vortex, danger of possible blade surface and runner chamber cavitations’ pitting and power losses. In the research, the ways how to predict vortex flow an...
ABSTRACT This research presented a new method for the mass production of a high quality, low cost, sheet metal products using a die, press and transferring mechanism. The research presented a definition of the tool (die), its design parts and the types which differ as per the products and operations concerned. The researcher selected the progressive die used for mass production, for more elaborated studies because it combines a number of die design and function in one frame. Al Madinah Al Mu...
ABSTRACT Nigeria currently imports large quantities of Activated Carbon (AC), for its domestic usage, despite abundance of agricultural wastes (coconut shells, palm kernel shells, etc), that can be used as raw materials. Short-circuiting of heating elements and absence of inert gases inlet have been identified as major challenges associated with AC production in Nigeria. This work was designed to develop a batch reactor incorporating functional materials for production of AC using locally so...
