Joule–Thomson effect investigations on a cryogenic three‐fluid–three thermal communication heat exchanger
The present study investigates the Joule–Thomson (JT) effect due to pressure drop on three‐fluid heat exchangers (HXs) with three thermal communications. The increased miniaturization of cryogenic HXs has led to the introduction of the JT effect. The present study investigates JT effects on a three‐fluid HX with three communications presenting different JT effects, which leads to a rise or drop in effectiveness values. The study is carried out using finite element analysis and MATLAB, considering seven nondimensional parameters of which one is JT pressure drop. The highest effectiveness is achieved for the positive JT effect at the hot stream. This improved effectiveness at hot fluid is achieved by maintaining the size (number of transfer units) of the HX more than 3.1, along with the ratio of the cold fluid heat capacity to the hot fluid heat capacity above 0.8 and the intermediate fluid temperature above 0.7.
This study focuses on the thermal aspect of the pressure drop, considering Joule‐Thomson pressure loss for the three‐fluid heat exchangers with three thermal contacts.
This study is conducted using finite element analysis, considering seven dimensionless parameters.
The investigation displays that the positive Joule‐Thomson effect at hot and intermediate streams leads to increased effectiveness and displays a reverse trend for the negative Joule‐Thomson effect at hot and intermediate fluid.
