Abstract

In the present set of experiments, boiling regimes in saturated He II confined to a vertical rectangular (1 × 10 × 114 mm) channel are studied. These experiments are intended to model a cooling channel in a superconducting magnet. Measurements are made at temperatures of 1.7, 1.9, and 2.1 K at saturation pressure. The various regimes are achieved by changing the steady state heat input. Experimental results include high speed films taken of the helium near the heated surface and within the channel. From the films, the sequence of events for each boiling regime is described. This provides an insight into how one regime evolves to the next as the heat input is raised or lowered. Additional understanding is gained from temperature and pressure measurements of the system.
