Natural Convection from Horizontal Cylinder with Annular Fins

This book presents the natural convection heat transfer from a horizontal cylinder with annular fins has been studied numerically. The present numerical investigation is able to capture a complete picture of natural convection over an annular finned horizontal cylinder from where easy visualization of the plume structure and flow field over the tube-fin surface can be obtained pictorially. In the present study numerical simulations of full Navier-Stokes equation along with the energy equation have been conducted for a horizontal tube with annular fins of constant thickness by varying the Rayleigh number based on fin spacing. Chapter 1 deals with the introduction and literature survey regarding the natural convection heat transfer from horizontal cylinder with annular fins. In Chapter 2 a complete numerical analysis of natural convection from horizontal cylinder with annular fins by varying fin diameter fin spacing and Rayliegh number. A similar analysis is carried out in chapter 3 taking eccentric fins on horizontal cylinder and results are compared with the concentric one. In chapter 4 an entropy generation analysis of finned tube configuration has been carried out.
