Thermal radiative flow of SWCNT+MWCNT+TiO2/Water based trihybrid nanofluid with bioconvection and Cattaneo-Christov flux model

The effect of Marangoni convective on thermal radiation flow of a SWCNT + MWCNT + TiO2/Water based ternary hybrid nanofluid across a disk in the presence of oxytactic and gyrotactic microbes is scrutinized in the current article. This article examines the Cattaneo-Christov law, which regulates the movement of heat and mass, rather than the conventional Fourier and Fick equations for examining the features of heat and mass transmission. Changes in surface tension gradients lead to the discovery of Marangoni convection. Among its many uses are crystal formation, drying silicon wafers, stabilizing soap coatings, and wielding. These novel fluids combine the bio-convection produced by microbes with the thermal features of many nanoparticles to increase the efficiency of heat transfer. This technique can optimize cooling in systems including chemical reactors, power plants, and electronic devices by improving thermal management, using less energy, and having a smaller environmental impact. Marangoni convection offers information for better cooling system performance and design when surface tension gradients are significant. A trihybrid nanofluid is created by combining water, MWCNT (multi-wall carbon nanotubes), and SWCNT and T i O 2 . The ODE (ordinary differential equations) are solved using the Bvp4c shooting method. The findings indicate that although the microbe profiles for heat, solutal, gyrotactic, and oxytactic processes exhibit the opposing pattern, the flow field upsurges as the Marangoni convection factor upsurges. Increasing the concentration and thermal relaxation factors specifically results in a decrease in the concentration and thermal fields.
