Lubricated stagnation point flow of Walters-B nanofluid with Cattaneo-Christov heat flux model: Hybrid homotopy analysis simulations

Abstract

Thermal mechanism of non-Newtonian nanofluid coated by lubricated power law material has been theoretically worked out. The slip interaction constraints has been proposed for inspecting the thermal transport. The modelling of heat transfer is processed via updated Cattaneo-Christov (CC) expressions. The rheological constraints of nonlinear model are observed by Walter B fluid. The flow phenomenon is governed by stagnation point flow. The differential system is associated to interaction of similarity variables. The solution technique is based on new developed hybrid homotopy analysis scheme. The hybrid homotopy algorithm is developed by combining the shooting technique and traditional HAM. The accuracy regarding the developed scheme is carefully inspected after making comparison of results with earlier claimed studies. The different physical aspect of transport phenomenon is attributed in view of parameters.
