【 摘 要 】

Hybrid nanofluids have generally been used to improve the applications heat transfer as a heat exchanger due to its significant thermos-physical properties compared to conventional fluid. In this article, 3D axis symmetric flow and heat dissipation over a hybrid nano fluid containing copper-alumina stays in the base liquid water are presented. This flow passes over the biaxial porous stretching/lowering sheet under the force of hot air and Cattaneo-Christov heat conduction, which is short for the (AMH–HNF–TCCHF) flow model. The partial differential equations of the proposed model are adjusted through a suitable similarity transformation that generates the ordinary differential system with physical variation. To analyse the physical variations, simulation of ODE systems is performed through a novel numerical technique named the “Modified New Iterative Method” (MNIM), which has been proved to be fast, convergent, and reliable. The results of physical variations in the stretching/shrinking parameter, mass flux, thermal radiation quantity, the thermal relaxation parameter and the Prandtl number in the velocity and energy field are shown in the graphs. This model emphasises the importance of study in potential medicinal fields, especially in 3D objects and cooling procedures in industries.
