    Abstract: Integrally geared centrifugal compressors have been widely used in industry especially. Reliable design, good performance, low noise, no resonant frequencies in the operating range and cost effective machining and casting parts are the goals of the design. Computational Fluid Dynamics (CFD) tools have been widely used to optimize the impeller, diff... Show More

    Abstract: Most of industrial processes use a lot of thermal energy by burning fossil fuel to produce steam or heat for the purpose. After the processes, heat is rejected to the surrounding as waste. The absorption heat pump is becoming more important because it can be powered by these industrial energy wastes and hence, it poses no danger to the environment.... Show More

    Abstract: Most population in northern Sudan are supplied by surface water sources directly from the Nile for drinking and irrigation purposes. As noted, most of them suffer from chronic diseases such as cancer and kidney failure. Water is expected to be a major and direct cause of these diseases, so the aim of this study is to identify the components of surf... Show More
