An experimental and numerical investigation of capillary limit in an arterial heat pipe

“…Very little performance data is available in the open literature about the arterial heat pipe we tested. Existing work that is directly related to our research is limited to [17] , [19] and [21]. In all three plots it is clear that dry-out occurs once power is increased to 350 W.…”

“…This work presented experimental test results for the same test article as used in this thesis and a numerical model based on the work in the standard text on heat pipes by Chi [20]. Michel Garcia's thesis provides further details on the experimental work performed, including detailed information about the test apparatus [21].…”

“…A similar test apparatus was used in [19] and [21] [22]. Wakefield Engineering 120 series silicone oilw based thermal joint compound with a thermal conductivity of 0.735 -was used to minimize the thermal contact resistance between the mating surfaces.…”

“…A Lytron recirculation chiller, part number RCOl 1, filled with a 70% ethylene glycol to 30% water mixture supplied chilled fluid to the heat exchanger. Much of the testing was at 5°C and this value was chosen to avoid formation of ice crystals as noted in [21]. The cooling capacity of this chiller is rated at 500 W and it used R-134a refrigerant.…”
