application of fan in cooling down the engine
 
i am using application of fans to cooling down the hot fuel cell (engine). i used 2 types of fan, intake fan and exhaust fan. how to declare those fans? i have settle down with the design modeler and meshing. as i know i have to set the fan as fluid in cell zone condition in setup. but i have problems in boundary condition as i cannot declare the intake fan. while for exhaust fan i have the option to do that. can u all help me? :confused:

Use the fan boundary condition. You will have to define the fa curve (velocity vs pressure drop)
