Characteristics of elastic deformation on Boger hybrid nanofluid using modified Hamilton–Crosser model: a local thermal nonequilibrium model

Abstract

In this investigation, elastic deformation characteristics on surface tension gradient flow of Boger hybrid fluid over a plate using modified Hamilton-Crosser Model are examined. The modeling takes into account the influence of local thermal nonequilibrium (LTNE). The expanded Cattaneo-Christov theory, which takes relaxation times into account, is the current theory for mass and heat transmission. Excellent heat transmission is offered by the energy equation-based LTNE model for both the liquid and solid phases. Therefore, in this work, two thermal distributions are used for both the liquid and solid phases. It can be applied to materials science to improve heat transmission procedures and nanotechnology, where accurate temperature control is essential for applications like electronic device cooling systems, microfluidic devices, and biomedical applications. Better modeling of complicated fluids in these systems is made possible by the addition of elastic deformation and LTNE, which enhances the systems' stability and efficiency, particularly under nonequilibrium heat conditions. The Bvp4c method is used to solve the model equation system numerically once the relevant similarity variables have condensed. To illustrate how different physical conditions affect the involved distributions, the findings are graphed. Results show that Boger fluid exhibits enhanced velocity at increasing solvent percent parameter values.
