| Summary: | Two dimensional steady hydromagnetic boundary layer flow of a viscous, incompressible, and electrically
conducting nanofluid past a stretching sheet with Newtonian heating, in the presence of
viscous and Joule dissipations is studied. The transport equations include the combined effects
of Brownian motion and thermophoresis. The governing nonlinear partial differential equations are
transformed to a set of nonlinear ordinary differential equations which are then solved using Spectral
Relaxation Method (SRM) and the results are validated by comparison with numerical approximations
obtained using the Matlab in-built boundary value problem solver bvp4c, and with existing
results available in literature. Numerical values of fluid velocity, fluid temperature and species concentration
are displayed graphically versus boundary layer coordinate for various values of pertinent
flow parameters whereas those of skin friction, rate of heat transfer and rate of mass transfer at the
plate are presented in tabular form for various values of pertinent flow parameters. Such nanofluid
flows are useful in many applications in heat transfer, including microelectronics, fuel cells, pharmaceutical
processes, and hybrid-powered engines, engine cooling/vehicle thermal management,
domestic refrigerator, chiller, heat exchanger, in grinding, machining and in boiler flue gas temperature
reduction.
