Numerical investigation on fin configuration improvement of 2 K sub-atmospheric plate-fin heat exchangers for the superfluid helium cryogenic systems

Rating and performance of plate fin heat exchanger used for cryogenic separation of CO 2

“…Thus, "h" increases with the increase in the temperature at a low concentration of CO 2 (10%). The empirical relation for calculating "h" is given by the Equation (30). 63 In other words, the value of "h" increases with the increase in the feed temperature.…”

“…Wen et al 30 proposed a PFHE that was made up of a new corrugated‐serrate fin for low‐temperature applications up to 2 K. The research focused on improving PFHE's flow characteristics and heat transfer performance. According to the findings of the study, the “ j ” of the new fin was increased in the range of 25% to 33.8% when compared to the serrated fin and in the range of 20% to 38.2% when compared to the corrugated fin 30 . Xu et al 31 proposed a mathematical model of a PFHE for helium at sub‐ambient temperatures.…”

“…The results indicated that the error between the experimental and predicted values of the “ j ” and “ f ” factors was found to be 11.3% and 22.5%, respectively 29 .

The overall performance of PFHE improved by increasing the fin spacing and decreasing the fin thickness.…”

Design Optimization of Plate-Fin Heat Exchanger in a Gas Turbine and Supercritical Carbon Dioxide Combined Cycle with Thermal Oil Loop

“…Haider et al [15] focused on the inlet configuration design to enhance the thermodynamic performance of plate-fin heat exchangers. Wen et al [16] carried out a numerical investigation on fin configurations of plate-fin heat exchangers. Moreover, researchers begin to employ artificial intelligence approaches to optimize the design parameters of plate-fin heat exchangers, such as neural networks [17].…”
