Abstract
Heat transport characteristics of liquid column oscillated forcedly in a straight channel with square cross section have been investigated. The channel wall was cooled in the inlet and heated in the end. The channel was initially evacuated, and ethanol was charged to form a liquid column, which is called single component system. In addition, the ethanol was charged in the channel with air in the gas phase at atmospheric pressure, which is called two components system. The results in single component system were compared with those in two components system. The contributions of latent heat transport and sensible heat transport are reported.
