Body forces on hovering airfoil
hii am solving a dynamic mesh case in which my flow is stationary and airfoil is performing hovering motion now i have given inlet velocity as 0 since flow is stationary but i want to calculate body forces due to motion of airfoil in fluid.
please kindly suggest what should be done in order to calculate lift and drag on body thank you |
Hi
I've never modelled a hovering airfoil, let's see if my comments make sense for you. Probably you need to perform transient analysis. I was thinking to do a steady state analysis for simplicity but I cannot find any way of doing it. Then you need to assign a predefined velocity to the wing according to the hovering trajectory you want. Probably all the points will have the same velocity at a given time if we consider the airfoil totally rigid. If the airfoil deforms substantially, you may need fluid-structure interaction. Hope it makes sense. |
