摘要

PPROBLEM TO BE SOLVED: To provide an analysis method of a bubble flow capable of accurately analyzing the behavior of the bubble flow where a gas and a liquid are mixed; to provide a bubble flow simulation program, a storage medium with it stored, and a bubble flow simulation device. PSOLUTION: In this analysis method of a bubble flow, the bubble flow is discretized with a plurality of vortex elements 16 and 17 by focusing attention on a vorticity field of the bubble flow where bubbles G and a liquid L are mixed; a vorticity transportation equation is formulated from a momentum conservation relationship and a mass conservation relationship considering a gas-liquid volume ratio (a bubble volume fraction SBg/SB, a liquid volume fraction SBl/SB) between the bubbles G and the liquid L in the bubble flow; and the behavior of the discrete vortex element is obtained from Lagrange calculation of the vorticity transportation equation.

要解决的问题：提供一种气泡流动的分析方法，该方法能够准确地分析混合有气体和液体的气泡流动的行为;提供一种气泡流动模拟程序，其存储的存储介质以及气泡流动模拟装置。

解决方案：在这种气泡流动的分析方法中，通过将注意力集中在混合有气泡G和液体L的气泡流动的涡度场上，使气泡流动通过多个涡旋元件16和17离散化。根据动量守恒关系和质量守恒关系，考虑气液体积比（气泡体积分数 g ，液体体积分数 l ），建立了涡度输运方程。在气泡流动中的气泡G和液体L之间;从涡度输运方程的拉格朗日计算中可以得到离散涡旋单元的行为。
