| Popis: | Reflection and evaporation as a result of oblique impingement of a thermal pulse on a He II free surface were experimentally investigated through the temperature variation measurement and with the aid of an optical visualization. A refracted evaporation vapor wave appears for small angles of incidence of a thermal pulse, and even a total reflection of an incident thermal pulse takes place at a free surface for larger angles of incidence than a critical value. In the present experimental study, the temperature reflection coefficient of a thermal pulse was measured. |
