- Abstract:
-
ANSYS Workbeneh is applied to the oplimization study on phase-change heat transler of plate heatexchanger with dimples. And the influenee of p, R, H,and P on thermal-hydraulic performanee is exploredwith Nu and fserving as the objective funetion. Results show that the volume fraetion of water vapor in thedimples is signifieantly higher than that on the plate near the dimples, which proves that the plate with dimpleshas the very good strengthening effeet on phase-change heat transfer; and, within the seope of the study ,thesensitivity of Nu and fon input parameters is basically the same , with a rank of o > R>H, >P, and the opli-mal struclure parameters is 7 mm
