Temperature boundary layer on a rotating surface - the problem of the
constant temperature wall

  

 

Introducing the group of Loitskanskii [1] form-parameters and transformations of Saljnikov [2], the set of governing equations of the incompressible laminar temperature boundary layer was transformed in the universal form, with Prandtl number as parameter, for the case of the constant wall temperature. Using the universal results for air (Pr = 0.72) the procedure for calculation of the Nusselt number (dimensionless heat transfer coeffcient) on the particular contour (airfoil NACA 0010-34) was developed. The dimensionless temperature profies within the boundary layer were presented also. The parameter of rotation W0, as well as Eckert number, was varied, and their influences on the heat transfer from the surface to the working fluid were presented and analyzed.
