Thermal transport characteristics of water-based casson hybrid carbon nanotube suspensions in a radiative channel

The carbon nanotubes significantly boost the effectiveness of heat exchanger performance owing to their extraordinary thermal conductivity. Their capacity to promote thermal conductivity, boost fluid mixing and reinforce the transmission of heat closer to the channel walls is what makes them so effective. Therefore, heat exchangers can release a larger quantity of heat energy in a small time, permitting them to grow more energy-effective and compact. Based on these applications, the current research focused on the radiative flow of water-based Casson hybrid CNTs passing through a heated porous channel. The regulating flow equations, originally framed as partial differential equations, are rendered into nondimensional ordinary differential equations via appropriate nondimensionalization techniques. Numerical solutions to these equations are subsequently obtained using Mathematica’s ND solver. The contrast of fluid velocity, temperature, skin friction coefficient and local Nusselt number under pertinent flow parameters is illustrated through graphs, tables and charts. Improving the value of the porosity parameter and Forchheimer number leads to reduced fluid velocity in the lower channel and it intensifies in the upper channel. The radiation and heat generation/consumption parameters strengthen the thermal profile for convective heating while they suppress it for convective cooling. Furthermore, the study shows that water-based HCNTs achieve a greater heat transfer efficiency than water-based single-walled carbon nanotubes (SWCNTs). The results improve insights into the thermal energy traits of nanofluids and carry significant impacts for electronic cooling, heat exchangers and thermal regulation systems for advanced materials.
