Hi! I made two airfoil (s1223 and naca4415) and one big rectangular to mesh for Fluid
and after some settings (I followed youtube video) I pressed calculation button. and then I 've got Lift Coefficient. But,,, it says the Lift coefficient is 220! I cannot understand the reason.. are there some problems in my ansys?  https://www.youtube.com/watch?v=bENclVrPeu4 this is what i followed for coefficient PLZ HELP ME

Hi, this is an old thread. But if anyone is still interested to run a simulation on the S1223 airfoil, please take a look at:
Numerical Investigation on the Pressure Drag of Some Low-Speed Airfoils for UAV Application. https://doi.org/10.37934/cfdl.13.2.2948 Unsteady 3-equation k omega intermittency SST was used. Good comparison with XFOIL and experimental data. Transition features also shown through cf and cp plots. Learn how I designed the mesh here: https://www.youtube.com/watch?v=qZRqBu9Ss2U |
