The peristaltic flow of nanofluids is a relatively new area of research.Scientists are of the opinion that the no-slip conditions at the boundaries are no longer valid and consequently,the first and the second order slip conditions should be addressed.In this paper,the effects of slip conditions and the convective boundary conditions at the boundary walls on the peristaltic flow of a viscous nanofluid are investigated for.Also,the exact analytical solutions are obtained for the model.The obtained results are presented through graphs and discussed.The results reveal that the two slip parameters have strong effects on the temperature and the nanoparticles volume fraction profiles.Moreover,it has been seen that the temperature and nanoparticles volume fraction profiles attain certain values when the first slip condition exceeds a specified value.However,no limit value for the second slip parameter has been detected.Further,the effects of the various emerging parameters on the flow and heat transfer characteristics have been presented.
Abstract
