    same study,internal or external?

    Hakam Al Zoubi

      hello,am using the flow simulation to calculate the torque on a wind turbine

      following this tutorial

      Solidworks Flow Simulation - YouTube

      i have noticed that he used internal study and set a computational domain

      i have thought of using external study in same conditions,atmospheric pressure and air velocity,so i did 2 studies in external and internal

      however i got completely different  result,there is no significant deference in pressure or velocity before the turbine blades between the two cases

      but the pressure and velocity is very different across it

      pictures shows pressure cut plots of turbine cross section of the two cases,and theirs a big deference in pressure ,so the torques were very different

      now why there is such a difference?and which one should i use?
