Abstract

For investigation of effect of local Prandtl numbers on wall similarity gradient, in this chapter the work on step 2 is performed for obtaining the system of data on coefficients and exponents \({a}_{1}\), \({b}_{1}\), \({a}_{2}\) and \({b}_{2}\) respectively at different value of local mixed convection parameter \(Mc_{x,\infty }\). The coefficients and exponents \({a}_{1}\), \({b}_{1}\), \({a}_{2}\) and \({b}_{2}\) are rigorously obtained with the optimal curve-fitting approach based on the system of the data on coefficient a and exponent b. On this basis, the coefficients and exponents \({a}_{1}\), \({b}_{1}\), \({a}_{2}\) and \({b}_{2}\) are attributed to the function of the local mixed convection parameter \(Mc_{x,\infty }\) respectively. In the next Chapter, our work will focus on investigation of correlation equations of the coefficients and exponents \({a}_{1}\), \({b}_{1}\), \({a}_{2}\) and \({b}_{2}\) with variation of the local mixed convection parameter \(Mc_{x,\infty }\) respectively.
