Abstract: Results of experimental investigation of the effect of the flow constraint and flow regime în the boundary layer of the cylnder, placed în the upstream, on the local characteristics of the flow and heat transfer to the second cylnder are presented. It is found that there is a critical value of the flow constraint at which the hydrodynamic characteristics change by a jump. A classification of flow regimes about a tandem of cylinders is given.
