冷却对浮力射流动力学特性的影响
Influence of cooling on dynamics of buoyant jet
摘要：
本文在具有水平非均匀密度和牛顿冷却的非静力学模型范围内，研究了引起向上窄射流产生的Rayleigh-Taylor不稳定性。分析表明，在这个模型中的不稳定性的总层次包括三个区域-崩溃，代数不稳定性，和惯性运动。这些阶段的实现、相互过渡和干涉取决于两个特征时间尺度--塌缩时间和冷却时间--之间的比率。
英文摘要：
The Rayleigh--Taylor instability which is responsible for the occurrence of narrow upward jets are studied in the scope of the nonhydrostatic model with horizontally--nonuniform density and the Newtonian cooling. As analysis shows, the total hierarchy of instabilities in this model consists of three regimes -- collapse, algebraic instability, and inertial motion. Realization of these stages, mutual transitions and interference depend on a ratio between two characteristic time scales -- collapse time and cooling time.
