Hi, i am a undergraduate student doing first formal course in CFD can anyone suggest me a good book relating to turbulance or/and free surface in CFD for my level.

(1). The best way to do is to look into the boos section of this forum first. (2). Check out these books from the library, and briefly go over the contents of the book, and flip through the pages, say 30 minutes. (3). Then, re-visit the sections of interest to you, after you have gone through all the books. (4). If you still have questions, then try to talk to your professor, or come back here post your message.

thanks for your suggestion.
