摘要：The flow field in the hyperbolic natural draft wet-cooling tower, which has great effects on the economyand security of power plant, was studied through numerical simulation. The mathematical model was established andanalysed in order to optimize the cooling-tower and to evaluate its efficiency and a Numerical study on a channelchimneysystem was carried out in order to elucidate the behaviour of heat transfer and fluid flow. A 2D CFD model ofnatural draught Cooling tower and chimney like heat sink plate is developed the Euler multiphase model was used tosimulate the heat and mass transfer in a natural draught cooling tower rain zone and the RNG turbulent model with thedispersed option is used for the turbulence modeling of multiphase flow. The results are presented in terms of local airtemperature measurements inside the symmetrically heated channel and between the adiabatic extensions.
