The behavior of hybrid nanofluids in engineering systems is greatly influenced by their thermophysical characteristics, specifically dynamic viscosity and thermal conductivity. Recently, various models based on artificial intelligence techniques have been developed to predict the features of these hybrid nanofluids. The properties of hybrid nanofluids are controlled by factors such as volume fraction, solid particle size, and temperature. This research aims to investigate the effects of non-thermal radiation and Ohmic heating on the motion of hybrid nanomaterials over a permeable stretching/shrinking cylinder.
The behavior of hybrid nanofluids in engineering systems is significantly influenced by their thermophys-ical characteristics. In the context of thermal sciences, dynamic viscosity and thermal conductivity are more important than others physical characteristics. In recent years, a number of models based on arti-ficial intelligence techniques have been developed to forecast these hybrid nanofluids features. The prop-erties of hybrid nanofluids as prospective heat transfer fluids are controlled by several factors such as volume fraction, solid part size, and temperature. The purpose of this research is to investigate the impacts of non-thermal radiation and Ohmic heating on the motion of hybrid nanomaterials over a per-meable stretching/shrinking cylinder. Through the use of the appropriate transformations, the problem's governing equations are converted into ODEs. The comparison of ordinary fluid (water), nanomaterials (Al2O3), and hybrid nanomaterials (Al2O3 + Cu) is addressed. The hybrid nanofluids are found to be supe-rior to nanofluid as a heater when the magnetic parameter is increased, but superior as a cooler when the Eckert number is raised. Further, it is observed that the skin friction coefficient and heat transfer rate reduce as the curvature parameter rises. (c) 2022 THE AUTHORS.
