Chemically reactive hybrid nanofluid flow past a Riga plate with nonlinear thermal radiation and a variable heat source/sink

The suspension of nanoparticles in base liquids has found extensive applications in various industrial processes like nanomedicines, microsystem cooling, and energy conversion. Owing to its important applications, this article investigates the hybrid nanofluid flow over a three-dimensional stretching surface. The fluid is influenced by thermal radiation, chemical reaction, and a variable thermal source/sink. The set of equations that administer the fluid behavior has been transformed to dimensionless form by a suitable set of similarity transformations that are further solved by the homotopy analysis method. It was found that as the ratio parameter increased, the velocity of hybrid nanofluid velocity decreased along the primary direction and increased along the secondary direction. The temperature characteristic was augmented with greater values of nonlinear thermal radiation and source/sink factors. Growth in the chemically reactive factor and Schmidt number has an adverse effect on the concentration profile of the hybrid nanofluid flow. A comparative analysis of the current results and those established in the literature was conducted. A close agreement with those published results was found. It was noted that temperature and concentration increase more quickly for the MoS2 + MgO/H2O hybrid nanofluid than the MoS2/H2O, MgO/H2O nanofluids.

Automated summary

This article investigates the flow of a hybrid nanofluid over a three-dimensional stretching surface, influenced by thermal radiation, chemical reaction, and a variable thermal source/sink. The equations governing the fluid behavior have been transformed to a dimensionless form and solved using the homotopy analysis method. The results show that the velocity of the hybrid nanofluid decreases along the primary direction and increases along the secondary direction as the ratio parameter increases. The temperature characteristic is enhanced with greater values of nonlinear thermal radiation and source/sink factors, while the concentration profile is adversely affected by the chemically reactive factor and Schmidt number. A comparative analysis with published results shows close agreement, with the MoS2 + MgO/H2O hybrid nanofluid exhibiting faster temperature and concentration increases compared to MoS2/H2O and MgO/H2O nanofluids.
