Abstract: An experimental investigation of heat transfer from in–line tube bundle to laminar flow of aqueous foam was performed. One type of aqueous foam – statically stable foam flow was used as a coolant. The experimental setup consisted of the foam generator, experimental channel, three in–line tube bundles, measurement instrumentation and auxiliary equipment. During the experiments it was determined dependence of heat transfer intensity on flow velocity, volumetric void fraction of foam and flow direction. Apart of this, influence of tube position of the bundle on heat transfer intensity was investigated. Liquid drainage from foam flow influenced on the distribution of the foam's local void fraction across and along the experimental channel therefore heat transfer intensity of the different tubes was unequal. Experimental investigation showed that heat transfer of the frontal tubes to vertical foam flow is higher than that of the further tubes. Experimental results of tu!
be bundle's heat transfer to vertical laminar foam flow were summarized by criterion equation, which can be used for calculation of heat transfer rate from the in–line tube bundle to foam flow.
