Hi!!!
i have a question about wall functions and near-wall models. both are approaches to modeling the near-wall region. but what i cannot understand is why one can be used for high Re while if low Re is considered only near-wall models can be used and they are required. Would u mind to answer me this question...?? Thanks in advance!! |

different model for differet usage! I think each model has better performance for its own situation.

Thanks! but i dont know if this is the best answer. i mean, i'm completely agree with u that each model has a range where it works better, but the wuestion is why wall function cannot be used with low Re and then it is required to use only near-wall models??
why is not defined correctly for low Re?? |
