Radiative heat and slip effects on blood-based hydrodynamic film flow of Maxwell/Oldroyd-B cross nanofluids: a bioapplication

Abstract

Human blood has elastic energy deposited in the distortion of red blood cells. Due to this, blood behaves like a viscoelastic fluid. The Maxwell and Oldroyd-B fluid models are the best models having viscosity and elasticity properties. Due to the numerous biomedical applications of gold and silver nanoparticles, we assumed blood-based gold-silver mixed nanoliquid. This study explores the consequence of radiative heat and velocity slip on the thin film flow of time-dependent hydrodynamic Oldroyd-B and Maxwell cross nanoliquids. A relevant mathematical model is established and the modeled physical problem is resolved numerically using the bvp5c Matlab scheme after applying appropriate similarities. The stimulus of applicable limits on motion and thermic fields is discussed with graphs and tabular illustrations. It originated that the heat diffusion rate is high in Maxwell cross nanoliquid when associated with Oldroyd-B hybrid nanofluid. The increasing film thickness effectively enlarges the heat relocation rate of both fluids. Also, the rheological nature of Oldroyd-B and Maxwell liquids is not uniform. The results are validated and found good agreement.
