Abstract:Simple approximate design formulas (+-5%) for calculating the elongation of the idealized viscous flow channel of rare gas at Knudsen numbers Kn < 100 due to the open end effects. Rectangular channels with a large aspect ratio and circular channels are discussed. The elongation model is applied to a squeezed-film damper problem and a simple design formula is presented that approximates the end effects in the damper.
