Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The appearance and dynamical behavior of a He І-He II phase interface is experimentally investigated. The experimental mode in which nearly saturated He I initially at a little bit higher temperature
than the lambda temperature is cooled by sudden evaporative cooling is primarily employed in the
present experiment among several possibilities In this mode where an interface appears and propagates
downward, some dynamical aspects of an interface layer can be preferably investigated. The phenomenon
is investigated by the application of Schlieren visualization method, and by measuring the temperature
variation by superconductive temperature sensors and the pressure variation as well as the evaporating
vapor flow rate which can be converted into the cooling rate. |
