Abstract
A numerical study is assumed to analyze the small-scale influence of surface roughness near the boundary layer region of a heated rotating disk. To calculate the shear thickening and thinning behavior, we evaluate the base flow profiles and also examined the surface roughness by imposing the wall partial slip boundary conditions with radial and azimuthal anisotropic and isotropic roughness. Thermo-physical properties are adopted to study the following phenomena. Moreover, the impact of thermo-physical characteristics and solar radiation near the disk are also considered. For the transformation of governing PDEs into resultant ODEs, we consider a von Karman similarity transformation and then numerical solutions are achieved via shooting method (Runge-Kutta Fehlberg and Newton Raphson). The numerical results concerned with the base flow profiles are given physically interpreted through tables and graphs. The shear thickening and shear thinning base flow profiles are shown here. Correlations in term of velocity, temperature, and concentration are plotted graphically. The comparison of literature with present work is also presented here.
