文摘

Buoyancy and flow acceleration effects were analyzed theoretically. The improvement of buoyancy and flow acceleration parameters has been made. Thresholds of Bu and Ac were theoretically evaluated and agree with experiments. The experimental phenomena can be explained with improved Bu and Ac. A new heat transfer correlation was developed with improved Bu and Ac.
