Owing to the excellent thermo-physical aspect and stability, scientists are continuously working on viscoelastic nanoparticles to suggest different applications in the industrial system and engineering phenomena. This thermal contribution characterizes the thermo-migration of viscoelastic nanoparticles to improve the heat and mass transfer phenomena. The oblique stagnation point flow pattern is followed due to the stretched cylinder. The new concept of zero mass flux relations with active and passive control constraints has been used to increase or decrease the thermal process. This concept of active and passive control may be used significantly to control the heat transfer rate. The equations of flow problems are formulated in cylindrical coordinates in partial differential equations. The dimensionless variables are utilized to reduce the independent variables. Active and passive controls of thermo-migration of nanoparticles are utilized for concentration profiles. The coupled complex system of differential equations is numerically approximated by the Keller-box procedure. The graphical results for velocity, streamlines, Nusselt, and Sherwood numbers presented are discussed. Moreover, tabular data depicting the Sherwood number are also included. A comparison of the obtained result with existing literature as a limiting case has been done for solution accuracy.
