  • The procedure of solving the inverse problem for determining surface heat transfer coefficient between liquefied nitrogen and Inconel 718 workpiece in cryogenic machining [Elektronski vir]
    Hriberšek, Matija, strojnik ...
    The paper presents how the phase of nitrogen influences the surface heat transfer coefficient. The determination of the phase influence has been defined by resolving the inverse problem with ... conducted experiments and verified by the numerical simulation. The experimental part includes the temperature measurements in the material at the time when the nozzle moved across the plate. The results have shown that the surface heat transfer coefficient reaches maximum value of 75000 W/(m2K), when nitrogen is in liquid phase. From the FEM results, it can be detected that value for the surface heat transfer coefficient decreases with increasing temperature of boundary layer which has been created by liquefied nitrogen on the Inconel 718 workpiece.
