Heat transfer under mixed convection in vertical and inclined flat channels of the vacuum of the ITER reactor chamber; Teplootdacha pri smeshannoj konvektsii v vertikal'nykh i naklonnykh ploskikh kanalakh vakuumnoj kamery mezhdunarodnogo termoyadernogo reaktora ITEhR

The results of the experimental study on the heat transfer intensity from the flat surface of the vacuum chamber channel model inclined to the horizon at the angle 5-90 Deg, at different heights, heated length and low velocities of the water flux are presented. The specific flux on the heat transfer surfaces constituted 1.3-24.4 kW/m{sup 2}. The considered parameters range is specified by the interaction of the induced and natural convection by the flux significant stratification in the inclined channels.
