Abstract

In order to identify the impact cooling ability of liquid nitrogen (LN2) on difficult-to-machine materials, the Computational Fluid Dynamics (CFD) was used to simulate the impact cooling state of LN2 on titanium alloy. The results show that the diffusion direction of LN2 is wider and the effective cooling range is larger at a little injection angle. When the injection speed (flow rate) is larger, it is followed the lower cooling temperature and the larger cooling depth for titanium alloy. This study reveals that LN2 jet angle and impact velocity can play an important role in the cooling effect for titanium alloy components, and can provide a theoretical reference for difficult-to-machine metal workpieces based on LN2 cryogenic cooling.
