Abstract: Boger fluids have various applications in the scientific and engineering fields, including biomedical engineering, materials sciences, chemical process engineering, and other disciplines. The present study aims to examine the 2-dimensional, steady, incompressible circulation of Boger nanofluids across a curved Riga stretching sheet with the influence of radiation, viscous dissipation, thermophoretic particle deposition, and porous medium. The nonlinear partial differential equations are transformed into ordinary differential equations employing appropriate similarity variables. The Runge–Kutta–Fehlberg fourth-fifth order technique and the shooting scheme are employed to solve these equations. Graphical representations will be utilized to describe the effects of various nondimensional constraints on their respective profiles. The significant engineering coefficients are also analyzed. The results indicate that enhancing the solvent fraction parameter upsurges the velocity profile but significantly drops the velocity profile with increasing the value of relaxation time ratio. The radiation constraints will improve the temperature profile. The thermophoretic constraint decreases the concentration profile. Skin friction reduces with higher values of solid volume fraction and porosity parameter. The Sherwood number decreases with an increment in the values of the solid volume fraction and thermophoretic constraint.
