Heat and mass transfer analysis for thermally radiative Sutterby fluid along a stretching cylinder with Cattaneo–Christov heat flux theory.

The aim of this study must increase our understanding of heat and mass transfer in non-Newtonian Sutterby fluids, which are widely used in industries like polymer production. Especially when examined through the perspective of the Cattaneo–Christov heat flow theory, it greatly enhances diffusivity and thermal conductivity and introduces new theoretical possibilities by accounting for dynamic fluid characteristics. The impact of heat generation and absorption, mixed convection, and nonlinear thermal radiation along a stretching cylinder are all thoroughly examined in this work, which makes it significant. The convective boundary conditions are considered in this study. The formulated system of partial differential equations (PDEs) is converted into system of ordinary differential equations (ODEs) by employing appropriate similarity transformation. This adopted set of ordinary differential equation is tackled computationally utilizing the RK-Fehlberg 4th-order approach based on shooting technique. The impression of significant physical variable on thermal, velocity, heat transport, concentration, streamline, and mass transport are discussed graphically. The findings indicate that the velocity curve diminishes as the Sutterby fluid parameter increases. The thermal profile is enhanced by increasing the temperature ratio parameter and Biot number. Higher levels of the Lewis number are associated with a reversal tendency observed in the concentration profile and local Sherwood number. [ABSTRACT FROM AUTHOR]
