Limiting tensile strength of liquid nitrogen
Abstract
The method of pulsed liquid superheating in a tension wave that forms when a compression pulse is reflected from the liquid free surface has been used to investigate the kinetics of spontaneous cavitation in liquid nitrogen. The limiting tensile stress pn of nitrogen corresponding to nucleation rates J = 1020 - 1022 s-1 m-3 and the slope of the temperature dependence of the nucleation rate GT = dlnJ/dT have been determined by experiment. The results of experiments are compared with classical nucleation theory (CNT) and a modified classical nucleation theory (MCNT), which takes into account the size dependence of the properties of a critical bubble. It has been noted that experimental data are in better agreement with the results of MCNT than with those of CNT.
