Abstract

<p>In this paper, the computational fluid dynamics analyzes behavior of temperature and humidity inside of the cable covered with polyethylene. First, the computational fluid dynamics analyzes temperature and humidity in the cross-sectional direction in the cable for which the temperature and humidity were measured. Next, the computational fluid dynamics analyzes temperature and humidity in the extension direction assuming installation of the cable in the actual bridge. As a result, it was found that the unique behavior of temperature and humidity inside of the cable can be reproduced by considering the delay of phase change due to the complicated cross-sectional configuration inside the cable as a coefficient.</p>
