Heat transfer analysis on MHD Williamson hybrid nanofluid flow over a heated stretching surface: Aerospace features

The development of aerospace technology has resulted in the manufacturing sector being confronted with new requirements and challenges regarding the operation of their technological devices. In order to ensure that aeronautical equipment is being operated in a secure manner, it is of the highest priority that the failure causes be recognized and that the functional lifetime of essential structural parts be increased as early as feasible. More recent years have witnessed the creation of novel substances for use in aviation. Engine oil serves several purposes in an aircraft engine, including lubrication, cooling, cleaning, preventing corrosion, reducing noise, and accelerating the engine. Lubrication is the most significant factor. All of the mechanical parts would be destroyed if they were not serviced. This study is being done with the intention of reducing expenses by increasing the fuel mileage and flying distance of airplane parts, as well as prolonging the service life of aircraft parts. Based on the importance of the inspiration on magnetohydrodynamic Al2O3-Cobalt hybrid nanofluid flow over a stretching surface (SS) in the existence of porous medium, and thermal radiation are investigated. In this model we used Engine oil mixed with Al2O3-Cobalt nanoparticles. By using the suitable self-similarity variables, the PDE is transformed into ODEs. After then, the dimensionless equations are solved by using the MATLAB solver in Bvp5c scheme. Graphs and tables explain how the operational factors affect fluid flow efficiency. This is because hybrid nanofluids have a higher rate of heat transmission when compared to nanofluids.
