Boundary layer flow of nanofluids over a moving surface in a flowing fluid in the presence of radiation
Olanrewaju, P.O.; Olanrewaju, M.A.; Adesanya, A.O.

This study investigates the influence of thermal radiation on boundary layer flow of nanofluids over a moving surface in a flowing fluid. The plate is assumed to move in the same or opposite directions to the free stream. The governing partial differential equations are transformed into ordinary differential equations, a more convenient form for numerical computation, using a similarity transformation. The resulting ordinary differential equations are solved by shooting method alongside with sixth order of Runge-Kutta integration technique. To observe physical insight and interesting aspects of the problem in the presence of thermal radiation, the non-dimensional velocity, temperature and concentration field are numerically studied and displayed graphically for pertinent parameters. It is observed that radiation has dominant effect on the heat transfer and the mass transfer rate. It is further noticed that the heat transfer rate is consistently higher for a nanofluids with smaller value of Le and Pr while the mass flux rate is higher for a nanofluids with higher values of Le and Pr. The results were displayed in tables and in graphs.
