Dimensional analysis in Heat Transfer

摘要

The object of dimensional analysis is to reduce the number of parameters in a problem for ease of calculation and experimental economy. It follows that the best analysis will produce the mini- mum number of nondimensional groups. As these groups have physical significance, the nondimensionalizing technique must al- ways produce the correct scaling groups, and it might also be expected that this method should be applicable to a wide range of problems. The technique must, in short, be concise, correct, and consistent.
