Abstract
Here we disclose the hydrothermal characteristics of nanofluids transportation by a curved stretching surface. The curve sheet is assumed to stretch in a circular shape. Energy communication is developed by employing thermodynamic first law. Thermal radiation, Joule heating, and dissipation are addressed. Passive and active controls of nanoparticles at surface subject to thermophoresis and Brownian diffusion are incorporated. The nanoparticles are immersed in a base solution of water (liquid Di-Hydrogen Mono-Oxide) to scrutinize the thermal and solutal diffusion. The physical feature of irreversibility exploration is addressed. Furthermore, the first-order chemical reaction is examined. Suitable transformations reduces PDEs into the ordinary differential systems. Newton built-in shooting technique is used to construct the convergent solution. Noticeable behaviors of influential parameters on velocity, concentration, entropy rate and temperature are studied graphically. Surface drag force and mass and heat transfer rates are numerically computed versus several variables through tables. Velocity and temperature are augmented against the curvature parameter. Brownian diffusion and thermophoresis parameters have increasing behavior on temperature. An increment in radiation parameter enhances the entropy rate. Entropy optimization is augmented versus larger approximation of curvature parameter.
