摘要
The heat transfer processes of heat exchanger were investigated experimentally. This model consists of three vertical lines of horizontal tubes with five tubes in each. Tubes were arranged in a staggered order. Heat transfer of staggered bundle of tubes to upward statically stable foam flow was investigated experimentally. Heat transfer dependence on specific gas and liquid velocity was determined, Dependence of volumetric void fraction of foam on heat transfer was investigated also. Heat transfer rate dependence on tube position in the line of tube bundle was investigated experimentally. Experimental results of heat transfer of bundle Of tubes to upward statically stable foam flow were generalized using dependence between Nusselt and Reynolds numbers.
