Nonlinear stretching curved surface and Lorentz force effect on hybrid nanofluids with an activation energy

The present investigation describes the flow of a copper (Cu) and cobalt ferrite (CoFe2O4) hybrid nanofluid with water as base fluid across a curved surface stretched with nonlinear power-law velocity in the presence of Lorentz forces. The influence of Joule heating and heat source/sink on fluid flo...

description The present investigation describes the flow of a copper (Cu) and cobalt ferrite (CoFe2O4) hybrid nanofluid with water as base fluid across a curved surface stretched with nonlinear power-law velocity in the presence of Lorentz forces. The influence of Joule heating and heat source/sink on fluid flow has also been studied. Using a similarity structure, nonlinear partial differential equations are converted into ordinary differential equations which are numerically computed using the ODE analyzer. Skin friction, Sherwood number and Nusselt number are computed in addition to the momentum, mass and energy profiles. A comparison is analyzed through graphs, tables and results for linear and nonlinear surfaces. The heat sink lowers the temperature profile and the heat source elevates the energy field, which serves a purpose in the petrochemical industries for heating and cooling fluids. When the chemical reaction parameter expands, the concentration profile gets less molded, but the opposite tendency is noticed for a decrease in the chemical reaction parameter, which is advantageous for biological applications. The major finding of the study is that nonlinear surfaces exhibit more drag force, mass and heat rate than linear surfaces. Additionally, there was a decent agreement between our results and prior findings for surface drag force under restricted conditions.
