Impact of thermal-solutal stratifications and activation energy aspects on time-dependent polymer nanoliquid

Nanofluids are used in our daily life and have engineering applications due to their improving energy efficiency and heat transfer in different thermal systems. Nanotechnology and thermal performance have developed a great prospect for global scientists and researchers. In our research work, we have considered time-dependent Sutterby nanofluid by capturing the aspects of thermal radiation and stratification phenomenon. Additionally, features of activation energy and heat source-sink are considered. Transformation variables are used to reduce PDEs into nonlinear ordinary differential equations. To obtain the numerical results, we have used the bvp4c scheme. Through graphs and tables, we have demonstrated a comprehensive analysis for velocity, temperature, concentration profiles, skin-friction parameter, Nusselt number, and Sherwood number. It is analyzed that the temperature profile increases as the thermal biot number raises, also, the concentration profile declines when the Schmidt number raises.
