DescriptionIn this research, to take countermeasures for the snow accretion damage, we developed a simulator of realizing the snow accretion process in the following steps. Firstly, air flow analysis is performed by “Airflow simulator” developed by RTRI (Railway Technical Research Institute). Secondly, trajectory of flying snow is calculated by Basset-Boussinesq-Oseen equation using distributed of velocity of air flow. Thirdly, snow accretion analysis is performed by “Particle simulator” developed by RTRI. The shape modified by snow accretion is reflected onto the boundary conditions of the air flow analysis. In this year, snow accretion analysis for simple cubic shapes is performed in order to aim at system development and validation.
