Impact of thermophoretic particle deposition on heat transfer and nanofluid flow through different geometries: An application to solar energy

Abstract

• Temperature, mass and flow for nanofluid with TPD and thermal radiation • Three distinct geometries (cone, wedge, and plate) are considered • Velocity decreases with improved values of magnetic and porosity parameters • Thermal distribution enhances with rising radiation parameters • The rate of mass is augmented with thermophoretic parameter increase The influence of thermal radiation adds a new dimension to the study of flow and thermal transmission in a viscous fluid across a stretched surface. Radiative effects are extremely important in engineering and physics, particularly in technology used in space and extreme-thermal operations. Thermal radiation and thermal distribution research are significant in astrophysical movements, solar power machinery, and other industrial provinces. On the other hand, the results of research on the deposition of vaporizer particles on exteriors have been useful in a variety of engineering fields. Based on the above-mentioned relevant applications, the current work examines the temperature, mass, and flow distributions in the presence of nanofluid while considering thermophoretic particle deposition (TPD) and thermal radiation over three distinct geometries (cone, wedge, and plate). By selecting appropriate similarity variables, the equations corresponding to the proposed flow are translated into ordinary differential equations (ODEs). The RKF-45 approach and a shooting system are used to evaluate the reduced equations. The important factors that affect the heat, mass, and flow profiles are deliberated with the support of graphs. Velocity profile decreases with improved values of magnetic and porosity parameters. Thermal distribution enhances with rising radiation parameters. The concentration profile improves with the thermophoresis constraint, whereas the opposite tendency is found with the thermophoretic constraint. The rate of mass distribution is augmented with improvement in the thermophoretic parameter.
