Estimation radius regression in PLIC-VOF method for droplet evaporation

Heat & fluid flow conservation equations of carburant liquid droplet are solved by a semi-implicit method the Volume Of Fluid ( VOF ) scheme. A new technique radius regression estimation based on Piece-wise Linear Interface Calculation PLIC is developed. Numerical computation performed for stagnant droplets in evaporation natural convection (which takes into consideration buoyancy forces) and an air atmosphere at pressure 1 bar. The results presented form radius, area mass regressions, volumetric flow, temperature, surface vapor temperature evolutions taking account influence ambient initial component variations. Using time evolution color function, our related to instant detection volume fraction. This not affected changing droplet’s shape nor collecting synchronization with analysis.
