Thermal analysis of heat transport in a slip flow of ternary hybrid nanofluid with suction upon a stretching/shrinking sheet

Abstract

Understanding heat transfer in slip flow scenarios involving a stretching or shrinking sheet has immediate applications in numerous fields, including materials processing, production, and temperature management systems. This information supports the development of novel heat transfer methods and systems. Therefore the present study focuses on stagnant point flow and discusses the dynamics and thermal characteristics of ternary hybrid nanofluids with the application of Tiwari and Das nanofluids. It is assumed that the ternary hybrid nanofluids are present on a stretching/shrinking sheet. The slipping effects and suction boundary conditions are implemented. The simulation will be performed using the finite element method with the software package COMSOL Multiphysics 6.0. The system of ordinary differential equations (ODEs) obtained through similarity transformation will be solved numerically to obtain simulation results. The average velocity, temperature profiles, and Nusselt number patterns using non-dimensional parameters are also analyzed. These non-dimensional parameters include the stretching/shrinking parameter, ranging from −1 to 0.5, and the suction parameter and slip flow parameter, both ranging from 0 to 2. The ternary hybrid nanofluids under investigation consist of a combination of TiO2, Silver-Ag, and ZnO particles in a base fluid (water). The volume fraction of these particles in the base fluid will be tested from 0.03 to 0.3. It was found that when there are no suction and no slipping effects, the Nusselt number decreases for the shrinking case and increases for the stretching case. It is also concluded that when there is no suction or slipping effect, the average temperature profile increases in the shrinking case and decreases in the stretching case.
