Abstract

In the current work we study numerically the time-independent twodimensional, non-aligned (oblique) slip flow of copper metal-doped water-based nano-polymeric sol gels under radiative heat flux. Reynolds temperature-dependent viscosity model is employed for the solar coating rheology. The Tiwari-Das nanofluid volume fraction model and Maxwell-Garnet model are used to simulate nanofluid thermal conductivity. The transformed ordinary differential conservation equations are solved with the Runge-Kutta-Fehlberg scheme and shooting quadrature in MATLAB symbolic software. Validation of solutions is conducted with a Variational Iterative Method (VIM). The response in non-dimensional normal and tangential velocity components, temperature, wall shear stress, local heat flux and streamline distributions to variation in obliqueness parameter, radiation-conduction Rosseland number, thermal slip parameter, Reynolds viscosity parameter, nanoparticles volume fraction is described and interpreted at length.
