Aerospace aspects of electromagnetohydrodynamic dusty flow of hybrid nanofluid with entropy generation over a rotating disk

Abstract

A lot of work has gone into developing a new generation of materials for aeronautical uses in recent years. In an aircraft engine, engine oil serves a variety of purposes, including lubrication, cooling, cleaning, corrosion protection, noise reduction and propeller operation. The most crucial is, of course, lubrication. Needless to say, all moving parts would quickly wear out if they were not lubricated. The goal of this initiative work is to reduce costs by prolonging the service life of aircraft parts (structural and engine components), as well as improving fuel efficiency, load capacity and flight range. The relevance of the electromagnetohydrodynamic dusty nanofluid over a rotating disk with entropy generation is discussed in this study. To convert the fluid transport equations into ordinary differential equations, suitable self-similarity variables are used and the Runge–Kutta fourth order with shooting technique is used to solve them. Graphs and tables depict the effects of active parameters on the fluid's transport qualities. Graphs for Bejan number, skin friction and Nusselt number are also performed. The fluid phase velocity and dust phase velocity rise as the electric field is increased whereas the tendency opposes a magnetic field. The temperature of both phases decreases with the rise in fluid particle interaction parameters for temperature and the rate of heat transfer rises for the electric field.
