The metastability of low-pressure water in turbulent flow

Results are given of an experimental investigation of superheating of water at low pressures of $32$–$170$ kPa, which rises up the thrust adiabatic region $(d = 0.05$ m, $H \approx 20$ m$)$ of circulation loop at a velocity of $0.05$–$0.42$ m/s $(\text{Re} = ((9$–$72) \times 10^3)$. The values of maximal superheating of water relative to the saturation temperature in the cross section being treated are determined, as well as their dependences on the parameters of water flow. Based on the experimental results, closing relations are suggested.
