Influence of solar thermal radiations and convective boundary on Al₂O₃/ H₂O transient model efficiency

Riga plate is a new, sophisticated magnetic field device that may be created by adjusting a group of permanent magnets and a different electrode over a plane surface. The heat transport and fluid movement in such physical setup are of paramount interest and have numerous engineering and industrial application particularly in submarines technologies. Due to the fixed magnetics the field produced which imperatively affect the model dynamics. Keeping in mind the influential applications of such physical setup, the purpose of this study is to introduce a new model based scrutinization of heat transport of stagnation point flow of Al₂O₃/water along vertically oriented convectively heated Riga surface. The conventional stagnation point flow model extended for nano fluid via radiative heat flux, dissipation effects and the first order thermal slip.The values of thermal conductivity values estimated via Corcione model and achieved the final nano liquid model. For the results interpretation, the numerical scheme used and portrayed the results using different parametric ranges. The fluid motion is observed very slow due to stronger mixed convection and higher concentration of Al₂O₃ nanoparticles. The temperature is determined very high against the stronger convection effects and radiation number. However, the fluid layers in the vicinity of Riga surface have high heat transmission ability. Further, thermal slip and viscous dissipation effects also boost the temperature of Al₂O₃/water. Further, buoyancy number d resists the fluid movement and thermal boundary region reduces in the presence of buoyancy factor
