Abstract: I will present the problem of an unsteady magnetohydrodynamics boundary layer slip flow with heat and mass transfer of nanofluids. The analysis is carried on Cu-water and Al2O3-water based nanofluids. The thermal conductivity of the nanofluid is assumed to be a function of temperature and slip conditions are employed in terms of the shear stress. The similarity transformations are used to transform the governing system of partial differential equations (PDEs) into a system of ordinary differential equations (ODEs) and then solved numerically. The numerical values obtained for the velocity, temperature and concentration depend on nanofluid's volume concentration parameter, unsteadiness parameter, thermal conductivity parameter, slip parameters, magnetic parameter and thermal radiation parameter. The effects of various parameters on the flow, heat and mass transfer characteristics as well as on skin friction coefficient, and Nusselt number are presented and discussed through graphs and tables.
