Influence of various conditions of solar radiation on neutral temperature reduction

Abstract

Influence of changes in the solar radiation condition caused by the shade of a building such as the occurrence of cloudy weather during a certain interval and the track direction on the rail neutral temperature is investigated. For this purpose, numerical simulation is carried out. Through numerical experiments, it is found that the weather change does not result in the reduction in the neutral temperature, while the track direction may rise the rail axial load.
