This book provides a thorough understanding of fluid dynamics and heat and mass transfer. It shows students how to implement computational methodology into a computer code and solve complex problems on their own, including problems in heat transfer, mass transfer, and fluid flows. These problems are solved and illustrated through step-by-step derivations and numerous figures. This second edition contains new chapters on mesh generation and computational modeling of turbulent flow. Appendices present examples in ANSYS, STAR CCM+, and COMSOL.
