Discussion on boundary conditions for simplified numerical simulation of swirl velocity in a cylinder of engine; Engine nai swirl no kan`i suchi simulation ni okeru kyokai joken no kento

Abstract

A simplified and quantitative simulation to calculate a swirl velocity in a cylinder with short time and low cost was offered by one of the authors. But the discussion on boundary conditions for the simulation was not enough. In this paper, measurements of diminution of the swirl velocity in a vessel packed with a fluid and simulations corresponding to the measurements were carried out varying aspect ratio of the vessel. From the measurement and calculating results, boundary conditions were obtained. The validity of the obtained boundary conditions was discussed and the adequate boundary conditions were determined. 4 refs., 6 figs., 2 tabs.
