摘要: Abstract : The objective of this research is to experimentally investigate the transient operating characteristics a titanium-water loop heat pipe subjected combined steady-state evaporator input rate and steady-periodic acceleration field. For experimental investigation, field, in form sine wave, was generated using centrifuge table. Radial peak-to-peak values frequency wave were defined prior conducting each run ranged from 0.5g less than or equal ar 10g, 0.01Hz f 0.1Hz respectively. Evaporator condenser cold plate coolant temperature varied 300W Qin 600W 30 deg C Tcp 56 In some cases driven forces complimented thermodynamic improving LHP dynamical performance. However, converse also true that appeared counter excite natural frequencies LHP. This resulted immediate total failure operate, delayed failure, cases, operated stable manner but degraded condition.
