Answer 1

Answer:

'm working on the simulation of a 3D flow field flowing over an airframe/propulsion coupled system. I don't solve the inner flow of the fan, so I set the boundary conditions at the inlet and outlet of the fan, which,as to the external flow, is flow field outlet and flow field inlet. I have used the pressure_outlet in Fluent as the fan inlet boundary conditions of the external flow field, and the pressure_inlet in Fluent as the fan outlet boundary conditions of the external flow field . However, the result shows that the fan_inlet mass flow rate is not equal to the fan_outlet mass flow rate, which in physical is not correct . I am confusing about this problem
