Understanding engine lubrication, electronic device cooling systems, and chemical industry production processes require studying boundary layer flow with Newtonian heating boundary conditions with varied consequences. The optimal performance of practical applications necessitates the proper conditions where many practical engineering applications using Newtonian heating in their theoretical study, such as in heat absorption in solar radiation, and conjugate heat transference around fins. As a result, theoretical research on free convection flow at a stagnation point region subjected to time dependent was examined utilizing mathematical modeling of the fluid system guided by physical laws and principles. The effects considered and fluid system configuration were also emphasized in developing the mathematical model. The study aimed to investigate the impacts included in the flow problem when subjected to Newtonian boundary conditions mathematically. The fluid problem's system of partial differential equations was simplified using a semi-similar transformation, and it was then numerically solved using the Keller-box approach. The effects considered were critically analyzed in terms of profiles and physical quantities to understand the fluid behavior and thermal characteristics. The results revealed that adding nanoparticles to the fluid system improved the thermal characteristics of the fluid system by increasing the Nusselt number (Nu). Skin friction coefficient increases along with the nanoparticle volume fraction parameter. The skin friction coefficient increases as a result of increased friction at the boundary body's surface caused by the nanoparticle silt. [ABSTRACT FROM AUTHOR] |
