Visualization study on the condensation in a propylene loop heat pipe operating at condenser temperatures between 153 and 283 K

Visualization Study on Operating Performance of a Dual Compensation Chamber Loop Heat Pipe Under Acceleration Condition

“…The operating temperature under different heat loads and the two-phase flow patterns of the start-up phase and the steady-state phase were determined. For a propylene cryogenic LHP with a visual condenser, Yan et al [54,55] clearly observed two-phase flow patterns at the temperatures between 153 and 283 K, including stratified flow, slug flow, pseudo-slug flow and wavyannular flow.…”
