Momentum, Heat and Mass Transport

Abstract

Most of the transport processes occur near thin interfaces and boundary layers. Since fluid flow is governed by a coupled nonlinear system of partial differential equations, the calculation of transport processes in industrial applications can be quite a costly task. However, in many practical situations, the calculation of friction or energy losses in conduits, or the heat and mass transport at interfaces can be greatly simplified by using the so-called transport coefficients. These coefficients, which are based on analytical solutions or experimental data, are typically gathered as correlations based on dimensionless numbers, ready for use.
