Thermodynamic properties of Second-grade micropolar nanofluid flow past an exponential curved Riga stretching surface with Cattaneo-Christov double diffusion

In the current study, second-grade micropolar nanofluid flow past an exponential curved Riga sheet in the presence of Cattaneo-Christov double diffusion is studied. The slip impacts are considered. The model of governing equations in PDE's (Partial Differential Equations) form is formulated because of the boundary layer approximation. The suitable transformations of similarity variables are defined to implement the approach of Lie symmetry method to change the set of formulated PDE's into ODE's. Then bvp4c scheme is adopted to numerically describe the dimensionless expressions of ODE's. The influences of involving physical factors on the velocity, microrotation, temperature, and concentration distributions are plotted with the help of graphical figures. Numerical findings of involved parametric impacts against physically interested quantities which are skin friction, couple stress, Nusselt number, and Sherwood number are comprehensively described in tabular format. A comparison with the literature work is also conducted to check the validity of modeled problem. The values of velocity are found to be diminishing by an increment of second-grade parameter. The values of shear thickening increased and fluid viscosity enlarged but the increment of second-grade parameter ultimately fluid velocity reduced at Riga stretching curved sheet.
