Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial experimental validation of such software is performed using a wind tunnel with the final validation coming in full-scale testing, e.g. flight tests.

In the present book, fifteen typical literatures about Computational Fluid Dynamics published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on A computational fluid dynamics, multi-domain dynamics, molecular dynamics, etc. We hope this book can demonstrate advances in Computational Fluid Dynamics as well as give references to the researchers, students and other related people.
