چکیده    With every passing day,heat transfer enhancement in convectional base fluids plays a major role in several industrial and engineering processes. during this process,nanofluids attained great importance to enhance the heat transfer rate in convectional flows. keeping this into view,in this study,we analyzed the mhd flow and heat transfer characteristics of a dusty nanofluid over a stretching surface in the presence of a volume fraction of dust and nano-particles. we have considered two types of nanofluids; namely,cuo-water and al2o3-water immersed with dust particles. the governing partial differential equations are transformed into a set of nonlinear ordinary differential equations by using similarity transformation,which are then solved numerically using runge-kutta based shooting technique. we found an excellent agreement of the present results with the existing literature. the effects of non-dimensional governing parameters; namely,magnetic field,volume fraction of dust particles,volume fraction of nano-particles,porosity,mass concentration of dust particles and fluid particle interaction on velocity and temperature profiles for both fluid and dust phases are discussed and presented through graphs. also,skin friction coefficient and local nusselt number are discussed and presented in tabular form. © 2017 just.
