Investigation of heat exchange conditions in long-length flat channels in laminar flow regime

Results of the investigations of heat transfer in large extent flat channels with laminar mode of liquid flow and boundary conditions maximally approximating the operational conditions of real straight-flow chillers of new milk are considered. The scheme of the experimental installation, design of the models being investigated and the technique of mathematical treatment of the experimental results are described. During generalization of the experimental data a criterion correlation for the calculation and optimization of operational conditions of such devices is obtained. As the experience of designing of the normal series of straight-flow chillers shows, the obtained correlation has a good agreement with test results.
