SUMMARY:Development of Numerical Coupled Analysis Method by Air Flow Analy
 sis and Snow Accretion Analysis
DESCRIPTION:Kohei Murotani, Koji Nakade, Yasushi Kamata, and Daisuke Takah
 ashi (Railway Technical Research Institute, Japan)\n\nIn this research, to
  take countermeasures for the snow accretion damage, we developed a simula
 tor of realizing the snow accretion process in the following steps. Firstl
 y, air flow analysis is performed by “Airflow simulator” developed by RTRI
  (Railway Technical Research Institute). Secondly, trajectory of flying sn
 ow is calculated by the equation of motion for gravity and drag using dist
 ribution of velocity of air flow. Thirdly, snow accretion analysis is perf
 ormed by “Particle simulator” developed by RTRI. The shape modified by sno
 w accretion is reflected onto the boundary conditions of the air flow anal
 ysis. In this year, we show the results of the snow accretion analysis for
  simple cubic shapes in order to aim at system development and validation 
 and discuss the result of the snow accretion analysis for a train bogie mo
 del.\n\nRegistration Category: Tech Program Reg Pass, Exhibits Reg Pass\n\
