Theoretical Analysis on the Thermal Characteristics of Oscillating Heat Pipe

Theoretical analysis on the thermal characteristics of the looped oscillating heat pipe was given to predict oscillation characteristics affected by filling ratio, inclination angle and heating power. The numerical results show that the alternative expansion and compression of vapors make the working fluid keep an oscillating flow in the heat pipe. This oscillating flow is affected by the inclination angle, filling ratio and heating power.Copyright © 2010 by ASME
