Ratios of forces and forces moments as dynamic similarity criteria of various phenomena occurring in wind engineering, snow engineering and fluid dynamics

Abstract

The work concerns dynamic similarity criteria of various phenomena occurring in wind engineering, snow engineering and fl uid dynamics derived from ratios of forces and forces moments affecting these phenomena. Derived and analyzed in part I dynamic similarity criteria, mainly concern the following steady problems: 1. Fluid fl ows and fl ows past objects ; 2. Fluid-solid contact problems; 3. Problems of a solid fl oating on a fl uid with and without of the surface waves.
