Freezing of a Water Flowing Down the Pipe with Very Low Flow Rate
Komatsu Yoshimi
The Proceedings of the Thermal Engineering Conference ( The Japan Society of Mechanical Engineers ) 2019 ( 0 ) 0092 2019
<p>This paper is concerned with temperature drop and freezing for water with very small flow rate on an inclined V-shaped open channel in a low-temperature room. The relation between water surface velocity and flow rate is linear. The onset position of freezing and water flow rate show almost linear relationship. Additionally, the heat transfer coefficient decreases with increasing flow rate, however decreases more significantly when the flow rate is small.</p>

Development of Drainpipe to Prevent Pipe Blockage Caused by Freezing
Komatsu Yoshimi, Goto Yuta
The Proceedings of the Thermal Engineering Conference ( The Japan Society of Mechanical Engineers ) 2018 ( 0 ) 0118 2018
<p>This paper is concerned with a pipe blockage caused by freezing of drain water. In cold districts, snow on the roof melts because of the building's heat and flows down through a drainpipe. However, when the outside temperature is sufficiently low, the water inside the drainpipe freezes, possibly blocking the drainpipe with icicles. We developed a drainpipe that can prevent pipe blockage without heat sources, just by improving shape of the drainpipe inner wall. In addition, we confirmed that the anti-freezing effect could be improved with changing outlet shape of the drainpipe.</p>
