Study on condensation characteristics of vapor with non-condensable gas in corrugated tubes
This paper presents a numerical investigation on the condensation characteristics of vapor with non-condensable gas in corrugated tubes. Several 2D examples with different corrugated structures
air contents and Reynolds numbers are studied and compared. Results show that along with the increase of air content
the wall average heat transfer coefficient decreases in the corrugated tube. The oscillation of fluid flow and heat transfer is generated due to the corrugated structure. With the increasing of wave height
the skin friction coefficient increased
and the wall average heat transfer coefficient first increased
and then decreased
the maximum of wall average heat transfer coefficient in this paper is in 0.032 m. The influence of wave height on the flow and heat transfer characteristics is more obvious than the width of the wave node and the space between two waves. The effect of inlet fluid flow-rate on the skin friction coefficient is also evaluated and discussed to provide some guidelines for future engineering applications.
