Unsteady hydromagnetic chemically reacting mixed convection MHD flow over a permeable stretching sheet embedded in a porous medium with thermal radiation and heat source/sink

MSc (Mathematics) / Department of Mathematics and Applied Mathematics / The unsteady hydromagnetic chemically reacting mixed convection MHD
ow over a
permeable stretching sheet embedded in a porous medium with thermal radiation and
heat source/sink is investigated numerically. The original partial di erential equations
are converted into ordinary di erential equations by using similarity transformation. The
governing non-linear partial di erential equations of Momentum, Energy, and Concentration
are considered in this study. The e ects of various physical parameters on the
velocity, temperature, and species concentration have been discussed. The parameters
include the Prandtl number (Pr), Magnetic parameter (M), the Schmidt number (Sc),
Unsteady parameter (A), buoyancy forces ratio parameter (N), Chemical reaction (K),
Radiation parameter (Nr), Eckert number (Ec), local heat source/sink parameter (Q)
and buoyancy parameter due to temperature ( ). The coe cient of Skin friction and
Heat transfer are investigated. The coupled non-linear partial di erential equations governing
the
ow eld have been solved numerically using the Spectral Relaxation Method
(SRM). The results that are obtained in this study are then presented in tabular forms
and on graphs and the observations are discussed. / NRF
