Extended surfaces (fins) are employed in all parts of the processing industry, in transportation, commercial and domestic situations within heat exchangers for the transfer of energy. This book examines the techniques involved in the use of fins to enhance heat transfer. The authors focus on the critical analysis of the conjugate problem from the mathematical perspective and look at the solution and application to real engineering problems.
Introduction to heat transfer and extended surfaces: pioneering work of Harper and Brown/Gardner/Jacob; fundamentals of heat transfer; mathematical representation of heat flow across interfaces; concept of thermal resistances and controlling resistance leading to why the use of fins; common fin performance indicators - fin effectiveness, efficiency, surface enhancement and fin assembly augmentation; the process heat transfer design problem. One-dimensional fins and assemblies: Derivation of governing equations, boundary conditions and assumptions, isolated single fins; single fin attached to the primary surface and the introduction of the surface enhancement and the augmentation of the surface; assembly augmentation; non-uniform heat transfer co-efficient; free and mixed convection from a downward facing fin; radiation from the surfaces of fins, further consideration of the assumption with respect to one-dimensional heat flow through the assembly and fins. Two-dimensional fins and assemblies: Derivation of governing equations, boundary conditions and assumptions; various geometries; the conjugate problem; mathematical methods; augmentation of assemblies. Important physical effects associated with two-dimensional fins and assemblies: Rectangular and cylindrical fins; convection - uniform and non-uniform coefficients, Radiation from the surfaces of the fins and primary surface; convection and radiation; perfect contact; temperature dependent physical properties, conductivity, heat transfer coefficient; application of augmentation factors to specific fin assemblies; axial conduction in longitudinal finned tubes. Transient heat transfer in one-dimensional fins and assemblies: Equations, boundary conditions and assumptions; augmentation; the isolated fin; the fin assembly; general periodic heating and cooling of fin assemblies. Two-dimensional transient heat transfer in two-dimensional fins and assemblies: Equation boundary conditions and assumptions; methods of solution; augmentation; isolated fins with various periodic heating and cooling, the fin assembly, general periodic heating and cooling of the system. Aspects of design using the one-dimensional and two-dimensional analysis of fin assemblies: Optimisation of fin assemblies; discussion of augmentation devices for both sides of a primary surface; what to do next.
