Publisher Comments

Integral Transforms in Computational Heat and Fluid Flow is a comprehensive volume that emphasizes the Generalized Integral Transform Technique (G.I.T.T.) and the developments that have made the technique a powerful computational tool of increasing practical interest. The book begins with an overview of the generalized integral transform technique that contrasts this approach with classical analytical ideas. The classical integral transform technique is then briefly reviewed. The remainder of the book is devoted to G.I.T.T. and considers diffusion-convection problems with variable equation coefficients in general functional form, situations of variable coefficients in boundary conditions, problems with variable boundaries, classes of problems with difficult auxiliary eigen value-type problems, and analysis of nonlinear diffusion-convection problems through this hybrid approach. Many applications are presented, including transient fin analysis with time-dependent surface dissipation, laminar-forced convection inside externally finned tubes, heat conduction with ablation in finite media, transient analysis of radiating fins, and boundary layer equations. Integral Transforms in Computational Heat and Fluid Flow will interest mechanical engineers in heat transfer and fluid dynamics, as well as researchers and librarians in this area.
