Camada limite de temperatura com gradiente de pressão adverso

The Prandtl's boundary layer energy equation has been solved by integral methods using a polinomial biparametric velocity profile with variable exponent as suggested by Geropp and a temperature profile presented by Van Driest which is modified to consider the presence of the pressure gradient. The compressible laminar boundary layer in an adverse pressure gradient is analyzed on the basis of the momentum and thermal integral equations. A method of calculating the boundary layer as function of the Mach number, uniform wall temperature and finite suction distribution is developed. The results obtained agree with the availables exact soluctions and the accurate approximate methods using different approach to solve the heat transfer problem and show that the solution of the thermal energy equation with the parametric correction of the pressure and temperature gradient are a mathematically simple and fast way to solve that problem.
