Precision optimization of reactive squeezing flow in stratified fluids: A response surface exploration

Year: 2024

Type: article

Abstract: Chemically reactive squeezing flows play a crucial role in various industrial and engineering processes , such as in polymer manufacturing, chemical reactors, and biofluid mechanics , where precise control over fluid behavior is essential for optimizing product quality and efficiency. Current study has focused on the chemically reactive squeezing fluid flow through a non-Darcy medium due to a stretching surface, employing response surface methodology . This research investigates the heat and mass transfer processes under convective conditions and non-linear stratification, with an emphasis on enhancing heat transfer through the incorporation of radiation effects. The non-linear governing system is solved numerically using the Runge–Kutta fourth-order method (RK-4) combined with the shooting technique. Critical parameter variations are illustrated through graphical representations , highlighting their impact on the relevant fields. The Nusselt number , Sherwood number , and skin friction coefficient are computed numerically for various parameter settings. Additionally, a comprehensive statistical analysis is conducted, utilizing the correlation coefficient and probable error to assess the influence of governing input variables on the output parameters of interest. The study also includes a sensitivity analysis, revealing that the sensitivities of the heat transport rate to the radiation parameter and thermal stratification parameter increase with higher Biot numbers . The high R 2 and R 2 − adj values, being close to unity, indicate that the proposed model demonstrates a robust empirical relationship between the responses and independent factors for both local Nusselt and Sherwood numbers.
