Heat transfer of a staggered tube bank under a flow of foam was investigated experimentally. The experiments were performed on a model of the heat exchanger. The cellular foam flow was used in the model as the heat transfer carrier. The experiments were accomplished for the middle and side rows of a three-row tube bank. The results of investigations are discussed with respect to the influence of tube position in the rows. Also, phenomena of the liquid deposition under cellular foam flow, as well as its influence on heat transfer intensity, are studied. This article is concluded with a simple heat transfer correlation describing the Nusselt number for the process in point.
