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.
