Answer Yes or No.
Hei,
FLUENT can plot the Drag force as belows In case of circular cylinder. 1. Monitor--Forces.. 2. Refort--> Forcse.. 3. UDF 4. Surface Integrals using Costoms Flied Funtions where pressure difference on the surface of circular cylinder. Drag force = pressure force + viscous force pressure force = intergral (static pressure - pressure coefficent) at circular surface. viscous force = Wall Fluxes--> X-wall shear Stress 5. Moment difference between inlet and oulet. Force = sum(Velocity inlet*density*Projected area*Vin) - sum(Velocity inlet*density*Projected area*Vout) Am i right??? YES or NO. Thank you very much for your answer. And. One more, If cylinder wall is not wall. it mean is porous-jump... How can get the Force on the surface of porous cylinder. Best regards Shim. |
