Slurry pipelines are used to transport solid materials using water for short or long distance. These pipelines are used in many industrial application involving transportation of coal and disposal of slurry in thermal power plant. Transportation through slurry pipeline is a safe, pollution free and reliable method. In the present book, rheological properties of bottom and fly ash are studied to know the flow behavior of coal ash slurry. Numerical simulation is performed on the slurry flow through straight pipe and 90° pipe bend for the evaluation of pressure drop per 100 meter length. Modeling of Straight pipe and 90° pipe bend is generated in Gambit version 2.2.30 and Fluent version 6.2.16 is used for the numerical evaluation. Simulation has been performed on various concentrations (10%, 20%, 30%, 40% & 50%), with additive (40% & 50%) for bottom and fly ash slurries at various flow velocities (10, 20, 30, 32, 40, 41m/s).
