Rinia Member Rinia Join Date: Jan 2018 Posts: 42 Rep Power: 8	Hi, CFDers I simulated a propeller with LES, but the thrust force obtained is smaller than the experiment, about lower 18%. Some paper said that the force in LES is usually smaller than the RANS. I would like to know how to increase the results by adjust the parameter, mesh or solver setting? Anyone could give me some advice? Thank you for any reply.
