Modeling and Numerical Analysis of Heat and Mass Transfer Phenomenon in Fluid Flow

Abstract

The phenomenon of heat and mass transfer occurs in almost every field of science and engineering as well as in nature. In the methods of power production, fluid flow and heat transfer processes are involved. Components used in the chemical and metallurgical in- dustries include furnaces, heat exchangers, condensers, and reactors, all of which employ thermo fluid processes. Heat transfer is frequently a limiting factor in the design of elec- trical machinery and electric circuits. Heat and mass transfer are significant causes of pollution in the natural environment, as are storms, floods, and fires. When the weather changes, the human body uses heat and mass transfer to maintain its temperature. Owing to these applications, investigation of heat and mass transfer in the steady-state flow of different industrial fluids through one/two-dimensional geometries has been carried out in the present research work. The current research work aims to analyze the physical problem and then develop a mathematical model that governs the fluid flow under differ- ent conditions using conservation laws for mass, momentum, energy, and concentration. For solving the modeled PDE s, a higher-order numerical technique i.e., the finite element method is applied. Further, the effect of the various embedded parameters on the flow, heat, and mass transfer traits are analyzed graphically. This thesis is comprised of seven chapters. Chapter 1 is introductory. This chapter provides the background of the proposed study, its development, applications, and other physical aspects involved in studying heat and mass transfer problems. In addition, some basic definitions along with the motivation behind the work are discussed briefly. The work done by the various researchers in the field of heat and mass transfer by considering different geometries is also given in this chapter.
