A thermal model for bio-convection transport of nanofluid due to stretching cylinder with Marangoni boundary conditions

This article examines the bioconvection impact on Marangoni convection flow of nanofluid past a stretching cylinder. The effects of Brownian motion and thermophoresis are considered. The impact of temperature-based thermal conductivity and diffusivity is taken into account. A multitude of nanofluid technologies was used in areas of electronics, automobile, and atomic science, effective heat dispersion and increased heat evaporation have been identified. Thermal transmission is necessary. The heat transfer rate can be increased due to the thermal conductivity of nanofluid. Due to the property of nanofluid, it uses in many applications in manufacturing, medical, and nanoelectromechanical systems. The system of PDEs is converted to ODEs by using similarities transformation. Resultant ODEs are solved by the bvp4c approach in MATLAB. Velocity field, temperature distribution, concentration and microorganism profiles are affected by flow controlling parameters. The graphical and numerical results are elaborated. The results of the current analysis designates that the velocity of a fluid is reduced for the magnetic parameter. The microorganism field shrinks when the Peclet parameter and the bio convectional Lewis parameter are increased. Furthermore, the microorganism profile is reduced by raising the Marangoni number and Marangoni ratio parameter.

Automated summary

This article examines the impact of bioconvection on Marangoni convection flow of nanofluid past a stretching cylinder. The study finds that the velocity of the fluid is reduced with an increase in the magnetic parameter. The microorganism field decreases with an increase in the Peclét parameter and the bioconvectional Lewis parameter. Additionally, the microorganism profile is reduced with an increase in the Marangoni number and Marangoni ratio parameter.
