THEORETICAL SCALING LAWS FOR SUBWAY MODELING

The report, prepared under the Institute for Rapid Transit (IRT) project, is one of many such reports leading to a final product--a subway environmental design handbook. A study is presented of the laws which scale the aerodynamic and heat transfer effects for vehicles in tubes. Aerodynamic scaling laws are found, under which the scaling laws for heat transfer by forced convection, free convection, and thermal radiation are derived. A discussion about the possibilities of applying these laws for small scale models is given, along with a summary of scaling laws.
