Thermal enhancement in solar aircraft by using MHD Carreau-Yasuda nanofluid with solar radiation

New demands and difficulties for the operation of electrical equipment have been proposed to manufacturers by the advancement of aeronautical technology. Finding the causes of failure and improving the operational durability of important structural components must be prioritized in order to guarantee the safe functioning of aeronautical gear. New airplane materials have been developed in recent decades. Lubricating, cooling, cleaning, avoiding corrosion, lowering noise, and accelerating are just a few of the many activities that engine oil carries out in an airplane engine. In this context, lubrication is quite important. Aerospace engineers in this research use nanofluids and MHD to extend the life of mechanical and electrical components of aircraft, which in turn reduces maintenance expenses. To enhance the fuel economy, overall performance, and flying range of aircraft, trihybrid nanofluids may be used to enhance heat transfer efficiency, and MHD can be used to optimize thermal management and flow behavior. These innovations aid in reducing component wear and tear, which in turn increases component lifetime and decreases maintenance expenses. The fact that nanofluids may have different thermal properties is a well-known fact. Using MHD and trihybrid nanofluids, this study investigates the performance of solar aircraft that are powered by solar energy and nanotechnology. Solar radiation, heat dissipation, heat sink/ source, and Ohmic heating are some of the thermal transfer parameters studied in pursuit of this goal. In a parabolic trough solar collector, the ternary hybrid nanofluid is thought to flow through the inner side. The current investigation examines the MHD Carreau-Yasuda trihybrid nano-liquid on a stretched surface that is convectively heated. Also investigated is the process of entropy production on the Carreau-Yasuda ternary hybrid nanofluid. A numerical technique is used to tackle the resultant system after using a non-similar transformation to simplify the fundamental boundary layer equations. Tables and graphs show the numerical results for various flow variables when applied to velocity profiles, local entropy numbers, temperature profiles, frictional forces, Bejan numbers, and local heat transfer rates. The key findings show that changing the values of the radiation parameter, heat source, and magnetic number improved the trihybrid nanofluid's temperature and local entropy number. Based on the findings, trihybrid nanofluid is the better option when compared to nanofluid and hybrid nanofluid. The heat transfer rates of nanofluids, base fluid, hybrid, and ternary hybrid nanofluids are enhanced with larger values of the parameters power law index, radiation, curvature, and the Eckert number. Trihybrid nanofluids outperform base fluids, nanofluids, and hybrid nanofluids in terms of heat transfer rate.
