Experimental Study On The Behavior In The Heat Exchanger Of A Mixed Gas Joule-Thomson Cooler |
| |
| Abstract: | In this paper, an experiment set has been set up and the experimental results of the mixed gas Joule-Thomson (J-T) cooler and its heat exchanger are provided. These data show that the temperature distribution as well as the pressure distribution in the heat exchanger channels depends to a large degree on the pinch point locations in the process, which is strongly influenced by the mixture composition. Both the pinch part of heat exchanging location should be considered for the optimal design of the heat exchanger as well as for the choice of the mixture composition. |
