Chapter 6 Fundamentals of Convection 6-35C A major advantage of nondimensionalizing the convection equations is the significant reduction in the number of parameters [the original problem involves 6 parameters ( L, V , T , T s , ν , α ), but the nondimensionalized problem involves just 2 parameters (Re L and Pr)]. Nondimensionalization also results in similarity parameters (such as Reynolds and Prandtl numbers) that enable us to group the results of a large number of experiments and to report them conveniently in terms of such parameters.
