Abstract
In recent years, the co-generation is expected from the viewpoint of utilization of the energy, The leading role of the co-generation is a heat exchanger that is very important equipment to transfer heat between high and low temperature fluid. The fluid used for cogeneration includes a lot of impurities and it is a problem that impurities deposit in a heat exchanger.In order to investigate the deposition in the heat exchanger of the co-generation,, experimental and numerical analysis are eemployed in this study. For the computation of the deposition, the continuum assumption of the many particles is employed to compute wall shear stress, and it was applied in combination with the continuity of particles volume. As the results of this study, it is clear that the position of the deposition is correspond to the high pressure region.
