In this study, a 2D numerical analysis was conducted to investigate electro-thermo-capillary convection in enclosure filled with dielectric fluid. The had free top surface and subjected buoyancy electrical forces. study considered strong unipolar injection of electric charge (C = 10), mobility number (M Prandtl (Pr 10). Calculations were performed for various thermal Rayleigh numbers (Ra) ranging from 5000 50,000, Marangoni (Ma) varying −5000 (T) 100 800. coupled equations governing the...
The present work is a numerical analysis of electro-thermo convection, occurring in square differentially heated cavity filled with dielectric fluid. experiences the combined effects viscous, electrical, and thermal forces. equations modelling physical problem are solved via finite volume approach. study focuses on effect tilt fluid flow structure performance inside enclosure under action an electric field. A parametric was performed, where angle getting varied between 0° 90°, as well...
Purpose The purpose of this work is to highlight the effects partial unipolar injection on electro-thermo-convection (ETC) in dielectric liquid contained between two eccentric cylinders. Design/methodology/approach A finite volume method was used solve governing equations. study performed for different parameters, such as radius ratio (0.2 ≤ Γ 0.6), dimensionless electric Rayleigh number (0 T 900), eccentricity (−0.4 e 0.4) and thermal (10 Ra 5.105). Findings It found that heat transfer...
This study explores the impact of an adiabatic obstacle on symmetry temperature, flow, and electric charge fields during electrohydrodynamic (EHD) natural convection. The configuration studied involves a square, differentially heated cavity with subjected to destabilizing thermal gradient potential difference between horizontal walls. A numerical analysis was performed using finite volume method combined Patankar’s “blocked-off-regions” technique, employing in-house FORTRAN code. covers...
