Thermal conductivity of nanomaterials potentially contributes in heat transport applications. Due to heat absorbing and cooling characteristics, nanoparticles broadly use in environmental engineering, solar plates, computational chemistry, chemical engineering and thermal engineering etc. Thus, it is substantial to identify the nanomaterials with effective heat generating or absorbing properties which have variety of applications in mechanical engineering. and Methodology: The main focus of this study are to introduce a nanofluid model using ZnO-SAE50 nanolubricant under additional effects of solar thermal radiations, magnetic field and resistive heating. This parametric study will help to maintain the temperature under various ranges of physical parameters which has broad applications in many engineering disciplines. The achieved model analyzed through numerical approach and comprehensive analysis provided in the view of furnished results. Investigation of the results provided that the heat transport is maximize using ZnO-SAE50 nanolubricant while; conventional SAE50 is not good to achieve desired heat transfer rate. Solar thermal radiations and dissipation effects positively act on the temperature role of ZnO-SAE50.
