About the Book
"Atul has championed the finite volume method which is now the industry standard. He knows the conventional method of discretizing differential equations but has never been satisfied with it. As a result, he has developed a principle that physical laws that characterize the differential equations should be reflected at every stage of discretization and every stage of approximation. This new CFD book is comprehensive and has a stamp of originality of the author. It will bring students closer to the subject and enable them to contribute to it"
- Dr. K. Muralidhar, IIT Kanpur
This book is primarily for a first one-semester course on CFD; in mechanical, chemical, and aeronautical engineering. Almost all the existing books on CFD assume knowledge of mathematics in general and differential calculus as well as numerical methods in particular; thus, limiting the readership mostly to the postgraduate curriculum. In this book, an attempt is made to simplify the subject for readers who have little or no experience in CFD, and even without prior knowledge of fluid-dynamics, heat-transfer and numerical-methods. The novelty in this book is on simplification of the level of mathematics in CFD to school education, by presenting physical-law (instead of the traditional differential equations) and discrete (independent of continuous) mathematics based algebraic-formulations.Another distinguishing feature of the present book is to effectively link the theory with the computer-program (code). This is done with more pictorial as well as detailed explanation of implementation of the numerical methodology. Furthermore, the book is structured for a module-by-module code-development of the 2D numerical formulation; the codes are given for heat conduction, advection and convection. The present subject involves learning to develop and effectively use a product - CFD software. The details for the CFD development presented here is the main part of CFD software. Furthermore, CFD application and analysis are presented by carefully designed example as well as exercise problems. The reader is trained for a job as CFD developer as well as CFD application engineer; and can also lead to start-ups on the development of "apps" (CFD application software) for various engineering applications.

ABOUT THE AUTHOR
Dr. Atul Sharma is currently Professor in the Department of Mechanical Engineering at Indian Institute of Technology (IIT) Bombay, with a teaching experience of more than 15 years. After completing his M.E. from Indian Institute of Science, Bangalore, he worked as a Lecturer at National Institute of Technology, Hamirpur (H.P.), where he introduced and taught a course on CFD. Later in 2004, he obtained his Ph.D. from IIT Kanpur; and worked on all the three aspects of CFD, i.e., Development, Application and Analysis. He taught CFD through distance education mode at IIT Bombay, from 2007-2010. He also delivered a course on CFD to more than 1400 college teachers from different parts of INDIA in 2012, as a part of a project under National Mission on Education. He is currently working on CFD development, application, and analysis for various types of multi-phase flow and fluid-structure interaction problems. He was a CFD consultant (2010-2014) for Global R&D, Crompton Greaves Limited, Mumbai. He is serving as Secretary, National Society of Fluid Mechanics and Fluid Power, since December 2014. He has close to 50 international journal publications and graduated 8 Ph.D. students so far.
