Peristaltic pumping of hybrid nanofluids through an inclined asymmetric channel: A biomedical application

This analysis addresses the application of highly effective nanomaterials namely single walled carbon nanotubes, copper dioxide and titanium dioxide in medical field from different aspects. The nanomaterials are brought into consideration with aiming to focus heat transfer enhancement of base liquid. Further the characteristics of nanomaterials are compared in terms of single phase nanofluid and hybrid nanofluid models. This inspiration leads to mathematical modeling of the problem subjected to Sorret and Dufur effects. Convection phenomenon is used to investigate heat transfer at the walls of channel. The mathematical formulation has been performed in asymmetric inclined channel. The equations are simplified by using small Reynolds number and long wavelength estimation. The governing equations with associated boundary conditions are solved via Mathematica software. The non-dimensional variables appeared in equations are discussed against velocity, temperature, concentration, streamline, skin friction, Nusselt number and Sherwood number. The results are compared for single phase nanoliquid (SWCNTs+water) and hybrid nanofluid (Cu+TiO2) models against physical variables. Hybrid nanofluid model leads higher temperature against inclination angle and Dufur number. Opposite trend is noted for mass transport against Sorret number. Furthermore, heat transfer in case of hybrid nanofluid model is noted higher than single phase nanoliquid model. The considered nanomaterials could be useful to boost heat transfer rate for targeted maligned tissues. The current study will help researchers to investigate other nanomaterials that could be used effectively as an alternative in medical fields.
