Numerical investigation on the Thermal-hydraulic performance of the modified channel supercritical CO₂ printed circuit heat exchanger

Printed circuit heat exchangers (PCHE) are designed to improve heat recovery and energy saving in supercritical CO₂ (S-CO₂) power cycles. In the current study, a modified channel PCHE is proposed based on the regular straight channel and a zigzag channel. The thermal–hydraulic performance of four different types of PCHE...
