Thermal radiation effect on SiC-Co3O4+Diamond/H2O trihybrid nanofluid with Stefan blowing and LTNE effects using classical and modified Hamilton-crosser models

Abstract
This study proposes to examine the effects of Stefan blowing and thermal radiation on the Marangoni convective velocity of a trihybrid nanofluid across a disk by using LTNE (local thermal non-equilibrium) effect and heat generation. Thermal and mass transfer properties are studied utilizing the Cattaneo-Christov mass and heat flux model. Nanoparticles of silicon carbide \r\n, cobalt oxide (\r\n, and diamond \r\n dissolved in water \r\n make up the trihybrid nanofluid flow model. In this work, the trihybrid nanofluid\'s rate of heat transfer based on diamond \r\n water is investigated by c contrasting the improved model with the Hamilton-Crosser model in its classical form. Thermal transmission efficiency in nuclear reactors, energy storage devices, and microelectronic cooling is improved by the investigation of Cattaneo-Christov flux in trihybrid nanofluids with LTNE effects. The design of effective cooling mechanisms in the automotive and aerospace industries is also aided by the optimization of thermal conductivity predictions through the use of classical and improved Hamilton-Crosser models. The system of PDEs is converted into a non-linear ODE system by applying the required transformations. The Bvp4c method is applied to solve this problem mathematically. When the values of the thermal and solutal relaxation parameters increase, the thermal and solutal distributions decrease.
