Hydraulic performance of a microchannel PCHE

Thermal-hydraulic characteristics and performance of 3D wavy channel based printed circuit heat exchanger

“…used in most of the previous work [6][7][8][9][10] on PCHE. Gauss-Seidel with an algebraic multigrid method is used in the flow solver.…”

“…The previous study on wavy channel based PCHE is reported for CO 2 [4,5] and Helium [6][7][8] as working fluid. The studies with helium is done at Re < 150 [6], 300 < Re < 800 [7] and 200 < Re < 2500 [8]; and is proposed here at 350 ≤ Re ≤ 2100.…”

“…For zigzag wavy channel based PCHE model, Ishizuka et al[4] and Nikitin et al[5] studied − experimentally as well as numerically − for mass flow rate varying from 40 − 80kg/h; and Kim et al[6] …”

Experimental and numerical study on thermal‐hydraulic performance of printed circuit heat exchanger for liquefied gas vaporization

“…Kim et al compared the thermal‐hydraulic performance of conventional zigzag channel PCHE and new PCHE with airfoil shape fins by numerical analysis; the results indicate that new PCHE has lower pressure loss being the heat transfer performance the same. Kim et al carried out a hydraulic performance test of a newly developed PCHE with a longitudinal corrugated flow path using helium. Based on the experiment, numerical models of different hydraulic diameters and dip angles are established, and the correlation of friction coefficient of PCHE is given by numerical simulation results.…”
