Abstract
In this work, the effect of dust particles and slips towards boundary layer flow of dusty nanofluid was investigated over the stretching horizontal sheet. Three type of nanoparticles; copper (Cu), aluminium oxide ( ) and titania ( ) were studied. The governing equations of flow and heat transfer were transformed into non-linear ordinary differential equations by using similarity transformation. Next, these equations were solved numerically by using the boundary value problem solver, bvp4c program of Matlab software. The effects of non-governing parameters including volume fraction of dust particles, volume fraction of nanoparticles, velocity slip parameter, and thermal slip parameter were computed, analysed, and discussed. Lastly, a comparison of present study with existing literature was performed and achieved excellent agreement. It is found that nanoparticles act as good thermal conductivity. Besides that, and show significant effect on velocity of fluid and dust phase.
