Research methods in the study of heat transfer coefficient during flow in minichannels

The paper presents the specification of research methods commonly encountered in studies heat transfer processes minichannels. In particular following have been emphasized: electrochemical limiting current method as well thermal balance method. mean coefficient is determined by set experimental measurements investigated exchanger. turn, based on and mass analogy. discussed implemented two specially designed constructed test facilities with compact minichannel exchangers, which presented described details. order to validate setup, preliminary exchangers hydraulic diameter 2 mm rectangular cross sections during single-phase liquid flows carried out. further perspective it planned extend compare results obtained both described.
