This paper investigates the effects of a non-uniform heat source and melting heat transfer on Casson nanofluid over a Riga plate in the presence of nonlinear thermal radiation with viscous dissipation. The effects of thermophoresis and Brownian motion are also taken into account in this study. The linked non-linear partial differential equations that regulate nanofluid flow are reduced to couple non-linear ordinary differential equations using local similarity variables and then numerically solved using the Spectral Collocation technique, as shown in the current flow mathematical modelling. The effects of flow control parameters on fluid flow, temperature, and nanoparticle concentration are shown qualitatively and quantitatively. As can be seen, the results clearly show that the newly investigated factors have a significant influence on Casson fluid viscosity, thermal and chemical species transmission.
