Abstract

The current paper focusses on the heat transfer characteristics in nanofluid MHD flow across a decelerated rotating disk with uniform suction. It is concerned with conventional von Karman flow pumping, but unlike a typical Newtonian fluid, it uses water-based nanofluids made up of TiO\(_2\), Al\(_2\)O\(_3\), Ag, CuO and Cu nanoparticles. The thermal energy equation was added to the classic von Karman flow problem in three dimensions. After employing the similarity transformations used by Watson and Wang, the leading equations transformed into a set of ordinary differential equations were numerically solved by using bvp4c MATLAB solver. Graphs were used to evaluate the behavioural study of heat transfer for various parameters. Furthermore, it can be stated that for a smaller Prandtl number Pr, the heat transfer rate is highest for all types of naofluids. The rate of heat transmission reduces as suction parameter A increases. The local Nusselt numbers are calculated and analysed and the path to enhance heat transfer is also proposed.
