Mixed Convection Flow of Magnetized Casson Nanofluid over a Cylindrical Surface

Abstract

This work aimed to establish a numerical simulation of kerosene oil as a host Casson fluid flowing around a cylindrical shape with an applied magnetic field crossing through it, under constant wall temperature boundary conditions. Nanoparticles of zinc, aluminum, and titanium oxides were included to reinforce its thermal characteristics. The governing model was established based on the Tiwari and Das model. Graphical and numerical results for correlated physical quantities were gained through the Keller Box method, with the assistance of MATLAB software (9.2). The combined convection (λ>0 & λ<0), magnetic parameter (M>0), Casson parameter (β>0), and nanosolid volume fraction (0.1≤χ≤0.2) were the parameter ranges considered in this study. According to the current findings, the growth of mixed convection parameter or volume fraction of ultrafine particles contributes to boosting the rate of energy transport, skin friction, and velocity distribution. Zinc oxide–kerosene oil has the highest velocity and temperature, whatever the parameters influencing it.

Energy transport boosters of magneto micropolar fluid flowing past a cylinder: A case of laminar combined convection

“…Thermo-physical properties of host liquid and nanosolids. 25,30,42 Material while its effects on the angular velocity and velocity profile occur by elevating their curves to higher values due to its increment, as indicated in Figures 17 and 18. Elevated values of mixed convection parameter boosted the buoyancy forces, which in turn decreased the temperature of the nanoliquid and raised its velocity and angular velocity.…”
