Mhd flow of nanofluids in the presence of porous media, radiation and heat generation through a vertical channel

Aim of present study is to identify the effects of radiation and heat generation in unsteady MHD mixed convective flow of nanofluids along a upstanding channel through porous medium. Four types of nanofluids were studied (i) Water based – Ag (ii) Water based – Al₂O₃. Water is taken as convectional base fluid and Ag and Al₂O₃ particles are incorporated in this base fluid. Keeping in mind the congregating and random motion of nanoparticles, "Koo and Kleinstreuer model" is used. The main characteristics of the nanofluids have finer thermo physical properties such as high thermal conductivity, minimal bloking in flow passage, long term solidity and uniformity. The governing boundary layer equations are formulated and reduced to a set of ordinary differential equations using perturbation technique. Solutions are obtained for motion and temperature, discussed and pertinent results are shown through graphs.
