Fluid Dynamics presents an organized structure to solve a variety of realistic problems related to fluid flow using experimental laws resulting from flow measurement. This book provide an inclusive description and analysis of some problems related to incompressible, viscous free convective fluid flows with effect of heat Source/Sink, magnetic field, variable heat and mass transfer, mass diffusion and chemical reaction. The techniques, data and analysis provided in this book would be helpful for researchers, scientists and technocrats in various fields of engineering, science, technology, astrophysics and space dynamics etc.
