Hello everyone
I'm currently simulating flow and thermal field for a car body and am considering developing a axis symmetric boundary condition. The tunnel and the car body is entirely symmetric lengthwise let's say. I've tried to find research done on this example but was unable to find any. What type of flow behaviors could I expect which would not be axis symmetric? I've thought of vortex shedding which would not be axis symmetric but since I'm not interested in drag I don't think it matters. Reynolds number in the domain will vary around approximately 50 000 so it's well into the turbulent zone. Are there any more errors I should think of or do you have any research papers that you think would be good to read? Please let me know. |

When simulating flow and thermal fields around a car body using axisymmetric boundary conditions, it's important to consider potential flow behaviors that may deviate from axisymmetry. While vortex shedding is one possibility, as you mentioned, there are other factors to consider, especially given the turbulent nature of the flow at Reynolds numbers around 50,000.
