Insight into Unsteady Separated Stagnation Point Flow of Hybrid Nanofluids Subjected to an Electro-Magnetohydrodynamics Riga Plate

The main objective of this work is to analyze and compare the numerical solutions an unsteady separated stagnation point flow due a Riga plate using copper–alumina/water graphene–alumina/water hybrid nanofluids. generates electro-magnetohydrodynamics (EMHD) which expected delay boundary layer separation. energy equations are mathematically developed based on assumptions. These then simplified with aid similarity variables. results generated by bvp4c function presented in graphs tables. limitation model use as testing surface water base fluid. may differ if another wall surfaces or fluids considered. Another Takabi Salehi’s correlation nanofluid used for computational part. findings reveal that dual exist where first solution stable validation from stability analysis. Graphene–alumina/water has maximum skin friction coefficient while thermal larger acceleration parameter. Besides, single nanofluids (copper–water, graphene–water alumina–water) also tested compared Surprisingly, alumina–water heat transfer rate. only conclusive limited comparison between graphene–alumina copper–alumina result fluid used. Hence, future study necessary investigate progress these
