β¦ Synopsis
The maximum heat flux density and the corresponding temperature drop during nucleate boiling of liquid nitrogen on the surface of high temperature superconductor ceramic samples were studied over a wide range of pressures. The experiments were performed during pool and narrow gap channel boiling. The stability of nucleate boiling and the dynamics of temperature rise of the ceramics were studied during heat transfer crises.

## Abstract The coupled radiationβconvection heat transfer of highβtemperature participating medium in heated/cooled tubes is investigated numerically. The medium flows in a laminar and fully developed state with a Poiseuille velocity distribution, but the thermal status is developing. By the discr
## Abstract An experiment has been done to measure the rise in temperature of a gas during filling a tank at high pressure. The experimental condition is that filling gases are nitrogen and hydrogen at a pressure of 5 to 35 MPa and at a filling mass of __G__=45 to 324 g/min for hydrogen. The temper
