Mass transfer measurements have a wide range of applications in science and industry. In some instances, the mass transfer is of prime importance - e.g. in wood and paper drying. In many cases, however, the mass transfer measurements are made to be used in the mass/heat transfer analogy. Here, the heat transfer can be calculated from the mass transfer results; an analytical solution for turbulent heat transfer is not generally possible as numerical solutions are limited by a lack of comprehensive model for the various physical properties required in the equations.
