In this paper, the preeminent perspective is to examine the flow of ElectroMagnetoHydroDynamic (EMHD) Casson nanofluid through a stretchable Riga plate with variable viscosity comparing two basic models, Reynolds and Vogel’s models. Brownian motion, thermophoresis and nonlinear thermal radiation is considered. Using appropriate transformations, The PDEs undergo a process of conversion to nonlinear (ODEs), and solved numerically with Bvp4c method. The main goal is to visualize the influence of some parameter, such as modified Hartman number (0.5 ≤ E* ≤ 1.5), Casson parameter (0.3 ≤ β≤ 1.1), dimensionless parameter (0.5 ≤ S ≤ 1.5), suction parameter (-0.5 ≤ fw ≤ 0.5), Prandtl number (1 ≤ Pr ≤ 10), radiation parameter (1 ≤ Rd ≤ 5), space-dependent heat source (0 ≤ Q ≤ 2), chemical reaction (0.5 ≤ γ1 ≤ 1.5), temperature-dependent heat source (0 ≤ Q* ≤ 2), Schmidt number (1 ≤ Sc ≤ 1.8) and Brownian motion (0.1 ≤ Nb ≤ 0.5) on Temperature and velocity profiles. The outcomes reveal that the modified number of Hartmann has a remarkable impact on the velocity profiles which leads to control the flow. In addition, the increment of radiation parameter causes to enhance the temperature.
