摘要：

The heat-transfer coefficients between a jet of liquid nitrogen and the inside surface of the tip of three different cryoprobes were measured by a transient method. Forced-convection nucleate boiling and unstable film boiling of liquid nitrogen in the cavity of the tip were investigated. The heat-transfer data was correlated in terms of dimensionless groups: Nusselt, Prandtl and Reynolds numbers, temperature difference and geometrical parameters. © 1979.
