Dynamics of stagnant Sutterby fluid due to mixed convection with an emphasis on thermal analysis

Due of high degree polymerization distributions, Sutterby model accurately projects it. In addition, in response to infinite shear stress, polymer aqueous solutions exhibit shear thinning and thickening liquid properties. For representing the characteristics of liquids at large stress magnitudes, the Sutterby fluid is thought to be the most accurate model. Thermal radiation affects Sutterby fluid non-Newtonian two-dimensional mixed convection nanofluid flow approaching stagnation point on a convectively heated stretched surface under aninclined magnetic field and convective boundary conditions. Similarity transformations turn the nonlinear flow equations into an ordinary differential equation system, which can be solved numerically using the boundary value method. Subsequently, we applied the boundary value technique to crack ordinary differential equations in MATLAB. An analysis of varied pertinent parameters on flow field such as mass and heat transport rates, temperature,velocity, and nanoparticle concentration patterns is computed. Inclined angle causes the momentum profiles of Sutterby flow to decelerate. Thermal radiation parameter values rise together with the temperature and the Nusselt number rises as well. Impact of Soret parameter reduces the temperature gradient driving the mass transfer and thereby decreasing the concentration gradients. Brownian motion, the random motion of particles due to thermal fluctuations, efficiently improves the mass transfer process, thus increasing the mass transfer rate.
