Abstract
Heat absorption/generation and homogeneous-heterogeneous reactions effects in stagnation point flow of rate type fluid towards moving sheet with nonlinear velocity and variable thickness are addressed. Radiation and viscous dissipation effects are ignored. A simple isothermal model of homogeneous-heterogeneous reactions is used to regulate the temperature of high melting surface. Thermodynamic processes of homogeneous-heterogeneous reactions analyze the effect of temperature phase changes, such as melting and evaporation. Computations for strong nonlinear systems are presented after non-dimensionalization. The behaviors of different involved variables on the velocity, temperature and concentration fields is studied in detail. The major outcome of the present study is that heat transfer rate decreases under the considerable effects of melting parameter and Prandtl number Pr. It is also observed that velocity field increases for larger melting parameter as well as Deborah number. It is observed that velocity of the fluid particle enhances for larger Deborah number. Further, lower Prandtl fluids have higher thermal conductivities contributing faster diffusion of heat in thicker thermal boundary layer structure when compared with higher Prandtl fluids in thinner boundary layer region.
