Multiple slips impact in the MHD hybrid nanofluid flow with Cattaneo-Christov heat flux and autocatalytic chemical reaction

The present study deliberates the nanofluid flow containing multi and single-walled carbon nanotubes submerged into Ethylene glycol in a Darcy-Forchheimer permeable media over a stretching cylinder with multiple slips. The innovation of the envisaged mathematical model is enriched by considering the impacts of non-uniform source/sink and modified Fourier law in the energy equation and autocatalytic chemical reaction in the concentration equation. Entropy optimization analysis of the mathematical model is also performed in the present problem. Pertinent transformations procedure is implemented for the conversion of the non-linear system to the ordinary differential equations. The succor of the Shooting technique combined with the bvp4c MATLAB software is utilized for the solution of a highly nonlinear system of equations. The impacts of the leading parameters versus engaged fields are inspected through graphical sketches. The outcomes show that a strong magnetic field strengthens the temperature profile and decays the velocity profile. Also, the fluid velocity is lessened for growing estimates of the parameter of slip. Additionally, it is detected that entropy number augmented for higher thermal relaxation parameter and Reynolds number. To substantiate the existing mathematical model, a comparison table is also added. An excellent correlation is achieved here.

Automated summary

This study examines the flow of nanofluid containing multi and single-walled carbon nanotubes submerged in Ethylene glycol in a Darcy-Forchheimer permeable media over a stretching cylinder with multiple slips. The mathematical model takes into account non-uniform source/sink impacts, modified Fourier law, and autocatalytic chemical reaction. Entropy optimization analysis is performed and the nonlinear system is converted to ordinary differential equations for solution using the Shooting technique and bvp4c MATLAB software. The study shows that a strong magnetic field enhances temperature profile and decreases velocity profile, while fluid velocity decreases with increasing slip parameter. Additionally, entropy number increases with higher thermal relaxation parameter and Reynolds number.
