SIMULATION OF DRIFTING SNOW

SCALE FACTORS BASED ON GEOMETRIC, KINEMATIC AND DYNAMIC SIMILARITY REQUIREMENTS ARE DERIVED TO SIMULATE DRIFTING SNOW IN A WIND TUNNEL. THE SCALE FACTORS RELATED TO THRESHOLD CHARACTERISTICS INVOLVE UNKNOWN FUNCTIONS THAT SHOULD BE DETERMINED IF A PROPER SIMULATION OF DRIFTING SNOW IS DESIRED. THE SCALE FACTORS DERIVED FROM THE EQUATION OF MOTION OF THE PARTICLES APPLY TO THE CONDITIONS WHERE LOW FREQUENCY TURBULENCE WITH LARGE EDDIES OCCURS. FURTHER RESEARCH IS NECESSARY TO EXTEND KNOWLEDGE OF THE MOTION OF PARTICLES IN A MEDIUM WHERE HIGH FREQUENCY TURBULENCE WITH SMALL EDDIES EXISTS.
