Effect of Internal Flow Patterns on Heat transfer Performance of a Closed-end Oscillating Heat Pipe at Vertical Position | Science Publications

摘要

> This article describes the effects of varying bond numbers (Bo) and aspect ratios (Le/d) on flow pattern of a close-end oscillating heat-pipe (CEOHP). The CEOHPs used employed a glass tube with inside diameter of 3 mm. The length of evaporator of 100 and 150 mm (the lengths of evaporator adiabatic and condenser section were equal) were employed with 10 turns. Observation of the flow pattern was conducted at 90
