Nonlinear coupled ODEs for nanofluid flow and heat transfer with varying thickness: A comparative study

In the Jeffrey and Williamson model of nanofluid flow and heat transfer past a moving surface with varying thickness, the effects of heat production, thermal radiation, Brownian motion, thermophoresis, and chemical reactions were considered. Controlling PDEs can be converted to nonlinear coupled ODEs by using proper similarity analysis. These ODEs are solved with the required boundary conditions via the BVP4c technique. Graphs have been used by researchers to show how restrictions on dimensions other than space impact fluid velocity, temperature, and concentration. The properties of both the Jeffrey and Williamson nanofluids are discussed and compared. The Nusselt number, Sherwood number, and skin friction coefficient are calculated numerically. Comparing the current study's outcomes to those that have already been published for a particular case allows us to determine that there is great agreement between the two sets of data.
