hi everyone, I am modeling two bladed rotorcraft domain that was set up as rotating for fluid domain and no-slip wall for blades. but results are not satisfactory. if anyone, has any experience about counter-rotating boundary and blades, can help me that b.c. for blades is convenient?
best wishes |

hi sachin, i am studing on my graduate work. i have cylindirical rotating fluid domain and at the center stationary two rotorcraft blades. my y+ is 1 and this corresponds to 0.0023 for first cell height.first, i set no-slip wall for blade and sst for turbulence model. i realized these bad results were brought about inadequate points along chord. but i did not find too explanation in cfx about counter-rotating boundary. i wonder about which circumstances are required in counter-rototing b.c?
