CHEMICALLY REACTING FLOW OF WATER- AND KEROSENE-BASED NANOFLUID IN A POROUS CHANNEL WITH STRETCHING WALLS

摘要

In this paper, a numerical study is performed to investigate the effects of heat source/sink and linear chemical reaction on the flow of water- and kerosene-based nanofluids in the presence of silver Ag and alumina (Al2O3) nanoparticles. Similarity transformations are used to transform the governing partial differential equations into a system of nonlinear ordinary differential equations which are numerically solved by the shooting method as well as by the implicit finite difference scheme, namely, the Keller box method. Influence of nanoparticle volume fraction, stretching parameter, and Reynolds number on the velocity profile is considered, while the effects of heat absorption on the temperature profile and chemical reaction parameter on the concentration profile for regular fluids (without solid volume fraction) and nanofluids are presented through various plots. Velocity, temperature, and concentration profiles are compared graphically using both numerical techniques. Skin friction, heat transfer, and mass transfer coefficients are presented and compared through tables via both methods.
