Melting and dissipative effects about entropy induced Darcy-Forchheimer flow involving ternary-hybrid nanofluids

Abstract

Here we examine melting heat in flow of ternary-hybrid nanoliquid bounded by stretching surface. Alumina (Al2O3), Silica (SiO2) and Copper Oxide (CuO) are three utilized nanoparticles. Conventional liquid employed here is water. Heat generation, dissipation and radiation comprise energy equation. Analysis of entropy generation rate is carried out. Implementation of adequate variables converts nonlinear partial differential system to ODEs. ND-solve approach is implemented to achieve solution. Quantities of interest are deliberated. It is noticed that an opposite trend of temperature for radiation and heat generation is found. Augmentation against melting heat and radiation for thermal transport rate is observed. Velocity decays for higher Forchheimer number. Reduction for velocity against melting and porosity is noticed. Temperature enhancement through Forchheimer number is witnessed. Rise in entropy production for Brinkman and Eckert numbers is noticed. Skin friction for Forchheimer number and melting variable has opposite trends.
