The Dynamics of a Drop of a Condensate in the Axial Gap of a Turbine Stage (O Dinamike Kapli Kondensata v Osevom Zazore Turbinnoi Stupeni),
Abstract
The stripping of a liquid film from the trailing edge of a turbine blade is accompanied by a wave motion. This causes the resulting droplets to oscillate periodically while being accelerated by the gas flow, their shapes being that of flattened spheroids. Effective radius changes of up to 25% have been measured from filmed sequences. As flattening results in higher impact forces, this parameter must be considered when estimating the maximum impulse during the collision of a drop with a turbine blade. (Author)
