Heterogeneous and homogeneous reactive flow of magnetite-water nanofluid over a magnetized moving plate

Abstract

This model is dedicated to visualizing the nature of magnetite-water nanoliquid induced by a permeable plate having variable magnetic effect, non-linear radiation, heterogeneous and homogeneous chemically reactive species. The system of momentum, thermal and concentration expressions is formulated and transformed from the partial to ordinary differential systems by using the adequate transforms. This highly non-linear system is solved through RKF (Runge-Kutta-Fehlberg) numerical method. Important parameters such as suction/injection, magnetic, and radiation effects as well as other relevant parameters are investigated. The graphs show that the rise in radiation parameter numerically improves the thermal distribution, implying a faster heat transfer rate. Non-linear radiation has greater effect on temperature than the linear radiation. While the volume concentration effect reveals that the friction factor increase with the enhancement of nanoparticle concentration. It is also observed that, plate velocity decreases the skin-friction but increases the wall heat transfer for both suction and blowing cases. The results indicate that the current research has a strong agreement with the relevant data in a limiting approach.
