Abstract

Abstract: The heat transfer technology is growing significantly for desired solutions as the need for efficient heating and cooling systems in the aerospace, automotive, and chemical sectors. Bearing this in mind the need for effective cooling/heating systems, the steady, two-dimensional Glauert wall jet flow with thermophoretic particle deposition is investigated in the presence of Al2 O3 nanoliquid. The Glauert transformations are used to transform the system of partial differential equations (PDEs) that reflect conservation, continuity, temperature, and concentration, as well as boundary conditions. The fourth fifth order Runge-Kutta-Fehlberg (RKF-45) method along with the shooting approach is used to solve the reduced system of ordinary differential equations (ODEs). The role of physical quantities for the parameters in concern are visually depicted and described in depth. Results reveal that, rise in values of velocity slip parameter upsurges the velocity profile away from the wall and declines near the surface. The increase in radiation parameter inclines the heat transfer. The growing values of both radiation parameter and volume fraction advances the heat transfer rate. The growing values of thermophoretic parameter improves the mass transfer rate.
