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 Failure of engineering components in service, especially in marine applications, has recently been a major global concern, and corrosion resulting from biofouling has been the primary source of these failures. Ultimately, biofouling and corrosion are detrimental to the lifespan of parts in service. Thus, there is a need to develop protective coatings which are highly resistant to the biofouling-corrosion system. This study developed affordable, eco-friendly and durable bi-phase of Zn...
ABSTRACT African nations have been characterized by conflicts, total war, slave trade, poverty of the highest order, corrupt leadership, undeveloped infrastructures, indisciplined society, we can go on to mention as many as the vices that estranged the continent. It is an irony to see all these in African continent, where civilization of the world began. For all these calamities that befell Africa, I sometimes wonder, if that is why the observation of our God in Genesis 6:5 was made. “The L...

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...
ABSTRCT Materials have been the milestones of progress. All civilizations have been categorized by the materials they used; The Stone Age, The Gold Age, The Silver Age, The Bronze Age, The Iron Age, etc. Some of these periods in history lasted centuries but in recent times both the rate of major materials breakthroughs and their improvements are increasing ever faster. Materials are constituents of the earth and the earth is materials. In Genesis 2:1, it reads: “In the beginning, God crea...
Abstract The Use Of Ferrous Gluconate As Corrosion Inhibitor On Aluminium Alloy In 0.5M H2SO4 Solution Was Studied Using Gravimetric And Potentiodynamic Polarization Measurements. The Surface Morphology Of The Aluminium Alloy Was Studied After Exposure To 0.5 M H2SO4 Solution In The Presence And Absence Of Inhibitor Using High Resolution Scanning Electron Microscopy Equipped With Energy Dispersive Spectroscopy (HRSEM – EDS). The Adsorption Behaviour Of The Inhibitor Was Investigated. T...
ABSTRACT The Stone Age, The Gold Age, The Silver Age, The Bronze Age, The Iron Age, etc. Some of these periods in history lasted centuries but in recent times both the rate of major materials breakthroughs and their improvements are increasing ever faster. Materials are constituents of the earth and the earth is materials. In Genesis 2:1, it reads: “In the beginning, God created the heaven and the earth”. So the earth was either created simultaneously with the heaven or it was c...
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 This study brought to the fore, a critical evaluation of the potentials of natural gas in the economic development of Nigeria. Natural gas option was considered the best alternative energy resource to other resources for optimizing income earning, indigent capacity building and the socio-economic development of an over populated Nigeria. Data and statistical reports from the various oil companies ere collaborated with the central bank economic report to determine the income generati...
Abstract A novel study on biomass-air gasification using a horizontal entrained-flow gasifier has been conducted. The use of a horizontal entrained-flow gasifier reactor was employed to assess the effect of the gasifier reactor orientation on the gasification process. The gasification experiments were conducted at 800˚C and equivalence ratio of 0.23 while maintaining gas hourly space velocity (GHSV) of 8000 h−1 . Preparation and characterisation of wood powder were performed using classic...
ABSTRACT Modelling is a very important tool for understanding complex problems. A model plays a fundamental role in the analysis, design and development of complex systems, especially when physical testing and experimentation are not feasible - or not possible at all. Modelling technology holds tremendous promise for reducing costs, improving quality, and shortening the time-to-market for manufactured goods. Unfortunately, this technology still remains largely underutilized by industries toda...
Abstract A charcoal fired reactor for small-scale production of biochar was successfully designed, fabricated and tested. The method of biochar production offered by this equipment was evaluated by comparing its output with a single barrel method of production. The results obtained during the test indicated that the efficiency of the equipment based on its output per kg of Cocoa pod husk was 79.9%. It has the capacity to produce 18.3 kg of Biochar from Cocoa Husk per day using lbag of local ...
Abstract: Adsorption refrigeration technology has been intensively investigated in many countries of the world because of its promising potential for competing with conventional vapour compression refrigeration, its relatively low operating cost and its environmental friendliness. The search for a good adsorbent for solar powered refrigeration technology has led to various attempts to manufacture activated carbon of high adsorptive property. In this study coconut shells plus 10% animal bones...
