TY - Generic T1 - Development of small-scale snowdrift simulation T2 - 50th Annual Western Snow Conference Y1 - 1982 A1 - Iversen, J.D. KW - Deposition rate, Drift geometry, Modeling, Wind tunnel AB - This history and development of snowdrift simulation is outlined, starting with work done by A. E. Finney nearly 50 years ago. Few attempts at small-scale simulation have been made through the years because of the difficulty of satisfying similitude requirements for two-phase flow. The modeling experiments that have been done are about equally divided between air and water as the modeling fluid. For this reason, and because of the problem complexity, controversies exist concerning the appropriate modeling parameters which must be satisfied. Also, because of the complexity of the similitude problem, many simulation attempts have been primarily qualitative. Since all important parameters cannot be satisfied, the appropriate parameters to be modeled depend on whether visibility, gross drift features, or other features of the depositional-erosional patterns are to be modeled. These similude requirements are discussed, and the efforts of the various investigators are compared and summarized.
