Prof SC Gupta has published a book on the title, ‘Applied Computational Fluid Dynamics’, Wiley India, 2019.
This book is written absorbing advance concepts and realizing these in form of algorithms. Keeping in mind the high ethical standards and sense of professionalism, the book is written to enhance the potential of learners in the computational fluid dynamics domain especially from the application point of view. Book starts with introductory chapters that include various forms of flow equations and their mathematical behaviors. Finite difference techniques, artificial viscosity, and their stability criterion are adequately covered.
Grid generation, adaptive grids generation both structured and unstructured grids to closely match how CFD meshing is applied, is explained. Variation methods for objective oriented optimal mesh generation are covered. Transformation of physical domain into computational domain and its` impact on difference equations is explained, keeping in consideration the grid as well the flow equation into account. Development of codes, algorithms for low drag configurations are brought out along with results from authors` own experiment with computational algorithms that are extensively highlighted. High resolution schemes in finite volume like Total Variation Diminishing, Hybrid differencing, Weighted Essentially Non Oscillatory (WENO) etc., are described in detail. Flux vector splitting, artificial dissipation and its` splitting in case of flux vector splitting, conservative smoothing, and flux limiters are explained. CFD application to laminar and turbulent boundary layers, and as well as for thermal is brought out. Laws of flow similarities are explained though results from computer codes. Design exercises are included.
Fortran codes are listed in few Appendices. Codes are meant to generate minimum drag surface camber and twist for subsonic and supersonic flow conditions, as well as perform optimisation in the presence of specified constrained region. Progression of transonic flow computations is possible though one of the codes. These codes can be run on Laptop utilising Fedora -12 Operating System that has a powerful Gfortran Complier.
It is hoped that the book is valuable as learning and teaching resource to support CFD courses at undergraduate and postgraduate levels. It intends to bridge the gap between fluid dynamics concepts, the academic CFD literature and applied industrial practice. A good grip of CFD is possible with good quality codes and with hands on experience with solutions for aerodynamically featured designs. The book will also be useful to professional engineers at industry, involved in R&D and design related work.
