This paper presents computational analyses of the effects of the nanoparticle’s shapes, heat, and mass transmission on the radiative nanofluid flow over a stretching Riga plate. Various nanoparticles shapes are considered, namely bricks- shaped, cylinder- shaped, platelets- shaped, and disk- shaped; those are governed using values of constants \(A\) and \(B\) in the correlations of the nanofluid dynamic viscosity. Besides, several significant influences are assumed such as constant Lorentz force, non-linear thermal radiation, viscous dissipation, heat generation, and convective boundary conditions. The solution methodology is based on similarity analyses and the obtained system is solved numerically. The entropy generation in all the aforementioned cases is examined. The given outcomes are represented in terms of the profiles of velocity, temperature, system entropy, and heat transfer rate together with the contours of the streamlines and isotherms. The findings disclosed that the sphere-shaped nanoparticles give higher values of the skin friction coefficient \(-{C}_{{\text{f}}}{{\text{Re}}}^{1/2}\) while the platelets-shaped cause lower values of \(-{C}_{{\text{f}}}{{\text{Re}}}^{1/2}\) . Additionally, the system irreversibility is enhanced as the thermal radiation coefficient \(\left({R}_{{\text{d}}}\right)\) , solid volume fraction \(\left(\varphi \right)\) , Brinkman number \(\left({\text{Br}},\right)\) or space-dependent heat source coefficient \(\left({Q}_{{\text{E}}}\right)\) is enhanced.
