Abstract
In this paper, the hot 2024 aluminum alloy thin sheets at 495°C were quenched by two spray nozzles with different pressures and water temperatures. The heat fluxes were determined using an inverse heat conduction method, and time–temperature curves were smoothed by B-spline approximation. The results indicate that there exists a film boiling regime and Leidenfrost point when water temperature is 70°C. The critical heat flux first increases and then decreases with increasing nozzle pressure. The critical heat flux decreases when water temperature increases from 25°C to 60°C. However, the critical heat flux increases when water temperature varies from 60°C to 70°C.
