Abstract

Quenching plays an important role in the material processing. Water impingement jet quenching involves phenomena such as nucleate boiling, Leidenfrost effect, rewetting, etc. Stronger thermal gradients could induce cracks in the material. Thermal boundary conditions of the process depends on temperature, space, time, and material discontinuity. This study mainly focuses on the thermal modeling of moving water jet quenching of semi-solid hot vertical aluminum plate with latent heat release during the solidification by using Peridynamics (PD). The obtained thermal profile is compared with the infrared camera’s thermal field data to identify the boiling curve parameters on the cracked plate. The PD model with the incorporation of cracking dynamics is giving agreeable results with the experimental thermal field. Modeling quenching heat transfer using PD will enhance the coupling of hot tear origination and propagation simulation, which is quite challenging with other numerical methods. The application of PD in quenching heat transfer with phase change is the first of its kind. The advantages and limitations of the peridynamic approach for this problem is critically evaluated and the simulated results are compared with the experimental measurement of temperature profiles.
