Simulation of entropy and heat and mass transfer in Water-EG based hybrid nanoliquid flow with MHD and nonlinear radiation

Abstract

The essence of heat transfer has always been a major aspect in the evolution of modern day industrialization. In order to enhance the heat transfer rate the fluids have also evolved from traditional fluids to more complex hybrid nanofluids. Here in this scenario a hybrid nanofluid flow consisting of Co ${\text{Fe}}_2{\mathrm{O}}_4$ and Ti ${\mathrm{O}}_2$ nanoparticles have been considered. The flow is drawn over a pervious stretchable cylinder concealed by the impacts of nonlinear radiation and magnetic field. The rate of heat transfer and entropy accumulated during the mechanism has also been evaluated for the system. This study of entropy provides a broader area of development for industrial organizations. The governing equations were solved by using the BVP4C tool of MATLAB. For this applicable similarity transformations were used to non dimensionalize the equations and then converted to IVP for obtaining the solutions. Both graphical and tabular form of the solutions were provided for better understanding of the situation. The novel results gained from the analysis concluded that the efficiency of heat transfer was more in case of hybrid nanofluid than that of nanofluid and the base fluid. The magnetic field inversely affected the velocity profile of the fluid whereas the nonlinear radiation directly affected the temperature distribution of the fluid. These results offer a variety of information for many large scale industries like food processing industries, plastic industries etc., to improvise their system.
