- Abstract
The present study deals with the numerical analysis of the coiled tube heat exchanger used in the Joule-Thomson (J-T) refrigerator. The performance of J-T refrigerator is analyzed with three different nitrogen-hydrocarbon mixtures. First, an attempt has been made to numerically examine the heat exchanger's performance. Temperature profiles are estimated and validated with existing test data. Low temperatures were noticed for the three mixtures when a wire fin coiled tube heat exchanger was used in J-T refrigerator. For the same amount of heat transfer, the lengths of heat exchangers are reduced by 33%, 28% and 30% for refrigerant mixture 1, mixture 2 and mixture 3, respectively. Further, the pressure drop on the shell and tube sides is estimated.
