Computational assessment of MHD Carreau tri-hybrid nano-liquid flow along an elongating surface with entropy generation : A comparative study

Case Studies in Thermal Engineering, Journal Year: 2023, Volume and Issue: 50, P. 103420 - 103420

Published: Sept. 9, 2023

This research looks at the incompressible, viscous, steady-state laminar stagnation-point-flow of a Carreau ternary-hybrid nano-liquid towards convectively heated expanding surface, taking into account first-order slippage and Ohmic dissipation. Viscous dissipation effects Lorentz forces are also considered. It is discussed how thermal radiation heat absorption/generation contribute to transport process. Minimizing entropy during ternary hybrid has been studied. In addition, convective circumstances used conceptually in numerical solution current model. tiny-particles silver (Ag), molybdenum disulfide (MoS2), multi-wall carbon nanotubes (MWCNT) analysed this work's flow study. As base fluid, carboxymethyl cellulose (CMC-water) used. With use appropriate similarity trans-formations, standard model equations transformed dimensionless form. Finding solutions for momentum fields using Runge–Kutta-Fehlberg technique shooting strategy. The figures depict wide range characteristics, including fluid velocity, temperature, skin friction, Nusselt number, minimization, Bejan number. Key results from present include fact that velocity curve flattens down as Weissenberg number increases.
