Abstract:
Fluid mechanics is not a subject to be studied for theoretical purposes only but its of much use in engineering and technology. Chapter one is introduction to the various specialized vocabulary of fluid mechanics. This helps the reader to become aware of the various applications of fluid mechanics in order to familiarize himself to the following chapters. Chapter two gives an account of the work which has been done by several researchers on natural convection boundary layer flows. In chapter three two basic concepts of heat and heat transfer, have been given. Importance of heat transfer, modes of heat transfer and material properties of importance in heat transfer have also been given. Simplified form of the Navier- stokes equation have been presented. with special attention on natural convection heat transfer,we have come up with the exact and approximate methods of a flat plate at zero incidence. Chapter four contains a research paper which is my original work on free convective flow through porous medium. Analytical expressions for the velocity and the temperature fields have been given. The effects of Grashof number (Gr) and the permeability parameter (K) on the velocity field have been shown graphically.
