Convective heat flow in space cryogenics plugs: critical and moderate He II heat flux densities

Cryogenics, 1990
Plug flow rates of entropy, heat and normal fluid in phase separators and in zero net mass flow systems are, to some extent, quite similar. A simplified analysis of critical conditions is presented in agreement with data trends. A critical temperature gradient arises on the basis of the He II two-fluid model at the stability limit constraining the ...

Influence of heat treatment on the critical current density of MgB2 bulk sintered in vacuum and flowing Ar atmosphere

Physica C: Superconductivity, 2008
Abstract Three types of boron precursor powders with a purity ranging from 90% to 99% from Alfa Aesar were investigated. A common magnesium powder was mixed with each type of the boron powders in a stoichiometric MgB 2 composition. The samples were heat-treated at 700 °C or 850 °C for 30 min in vacuum or in flowing Ar atmosphere.

Critical heat flux on a uniformly heated cylinder in a cross flow of saturated liquid over a very wide range of vapor-to-liquid density ratio

International Journal of Heat and Mass Transfer, 1987
Abstract Experimental studies of critical heat flux (CHF) on a heated cylinder in a cross flow have so far been made within a narrow range of vapor-to-liquid density ratios ρ v ρ 1 = 0.0006–0.005 . In the present study, systematic experiments of CHF on a d.c. Electrical current-heated, 1 mm diameter cylinder have been performed over
