Abstract
The major focus of this paper is to present experimental data, collected for three gases - nitrogen, helium, and carbon dioxide, at the deteriorated turbulent heat transfer (DTHT) regime in gas up-flow with near uniform heat flux. The data were collected for a range of (1) inlet Reynolds number from 1800 to 42,700, (2) inlet buoyancy number Boâ up to 1Â ÃÂ 10â5and (3) inlet acceleration parameter Kv up to 5Â ÃÂ 10â6. Based on the new experimental data, the traditional thresholds for the DTHT regimes are updated, and a new heat transfer regime map is proposed and compared to the existing experimental data.
