Lafond C. Principles of Convective Heat Transfer 2019

Textbook in PDF format Heat energy transferred between a surface and a moving fluid with different temperatures - is known as convection. In reality this is a combination of diffusion and bulk motion of molecules. Near the surface the fluid velocity is low, and diffusion dominates. At distance from the surface, bulk motion increases the influence and dominates. The field of convection has evolved as a sequence of solved problems. The first were the most fundamental and the simplest, and they bear the names of Prandtl, Nusselt, Reynolds and their contemporaries. As the field grew, the problems became more applied, more complicated, and much more numerous and forgettable. Hidden in this stream, there are still a few fundamental problems that emerge, yet they are obscured by the large volume. Heat transfer by natural convection phenomenon has been studied by diverse researchers for several geometries and different boundary conditions. Different approaches were used such as numerical, analytical, and experimental approaches. This book includes state of the art review and results on convection heat transfer with their obtained numerical, semiempirical, and/or experimental correlations for the last two decades. These correlations are very important for engineering applications. Controlling fluid flows with heat transfer is essential for designing and optimizing efficient systems and requires a good understanding of the phenomena and their modeling. The aim of this book is to familiarize the problems of convective heat transfer to readers who are not conversant with this topic. A good knowledge of fluid mechanics is clearly essential for the study of convective heat transfer. In fact, determining the flow field is most often the first step before solving the associated heat transfer problem. The knowledge of conductive heat transfer is, obviously, the second necessary ingredient for studying convective transfer. This book contains valuable innovative information mostly relating to flow and heat transfer in porous media and computational fluid dynamics along with current advances in turbulence modeling
