  7. Abstract:
  8. According to the recent researches it has been found that wind can reduce the efficiency of Air Cooled Condensers (ACC) which use for cooling purposes in power plants. Wind affects the natural suction of the cooling air and makes local low pressure area in fan’s inlet results to disrupt its normal performance. Using aerodynamic obstacles inside and around the condensers can compensate this lack of performance when there is strong wind. In this thesis with the aid of computational fluid dynamics, condenser’s behavior with various weather situations is studied. Simulation in no wind situation and different wind speeds is considered and accomplished with Gambit Fluent software. This simulation is helpful for quantitative study on destructive effect of wind in condensers. In next step designing aerodynamic obstacles with considering industrial experiences and previous studies is in hand, and then these designs will be study in no wind situation compare to various speed of wind in order to show the effectiveness of them in wind situations. For some instances guiding plates, porous walls and horizontal arils can be named. Studies show among all aerodynamic obstacles, horizontal walkway is the most effective plan for improving the performance of cooling system
