Abstract
Vapor film, nucleate boiling and convective phase are the cooling stages during quenching heat treatment process. This is a work based on simulation of first cooling stage of a carbon steel quenched in water. Knowing heat transfer behavior during hardening steel process is fundamental to understand metallurgical transformation. Computer fluid dynamics (CFD) is a tool based on applied mathematics and fluid mechanics that permits to simulate complex thermal fluid phenomena. The heat transfer of the quenchant during transition and nucleation cooling phases was simulated using StarCCM+, a CFD software. Using a transition model, this paper presents the simulation of temperature, volume of vapor phase and heat transfer coefficients around the steel sample during the first quenching stage.
