چکیده

The purpose of this study is to look at how gold nanoparticles affect the circulation near wavy biological cell walls. Non-linear thermal radiation was found to enhance the heat transfer rates of nanofluid flow by numerical calculations. The mathematical model was a temporally magnetized non-Newtonian Casson micropolar nanofluid flow through a heated vertical wavy surface. The importance of predicting heat and mass transfer for irregular surfaces cannot be overstated, as irregular surfaces are common in many applications, including refrigerator condensers and flat-plate solar collectors. For this reason, it is imperative to study heat and mass transfer in complex geometries. Furthermore, the fluid temperature factors like nanofluid viscosity and microrotation viscosity were taken into account. A graph comparing the published data and the present numerical computation revealed an exact match. A physical interpretation of images was provided to describe the phenomenon of blood flow by heat transfer according to various circumstances. In medical treatment, especially cancer therapy, these results are crucial. Gold nanoparticles are among the best particles because they are stable metallic nanoparticles with excellent catalytic, magnetic, and optical properties. The investigation's findings showed that as time-steps grow, each profile's effectiveness tends to decrease, moving the unstable condition closer to the steady state. Whereas, the sphere-shaped nanoparticles have a significant effect on temperature profile change, column-shaped nanoparticles have less effect. Local skin friction rises and the local Nusselt number falls when the values of the two surface amplitude parameters rise.
