hello everyone,
Recently I've been working on ribbed channel flow,and heat transfer is of great importance in this problem. I found that heat transfer coefficient distribution calculated by the k-e model (with enhanced wall treatment) are not quite satisfying compared to the experimental results. I wonder if there's some logic to guide me to choose a proper turbulence model, or I can only try them one by one?
Your remark are highly appreciated!
