Experimental studies on cu-ss diffusion bonded Perforated plate heat exchangers

In this paper experimental studies on Cu-SS diffusion bonded perforated plate heat exchangers (PPHEs) are reported. A test set up has been developed for testing the heat exchangers at cryogenic temperatures. The paper presents the details of the test setup, instrumentation and the test results. Due attention is given to the accuracy of the experiment. Data on frictional pressure drop have been obtained under isothermal conditions. These data are useful for observing the behavior of the heat exchangers. Besides, these will also be useful for validation of numerical models of PPHEs.
