密度锁界面下方稳态温度场的实验研究及分析

Experimental research and theoretical analysis on the temperature distribution under the interface in density lock on steady state

本文通过实验模拟了密度锁内分层界面下方流体稳态温度场分布，发现这部分流体的稳态温度分布曲线存在一个升温结束点，它是导热层与恒温层的分界，只有将升温结束点控制在密度锁内才能有效地抑制传热。本文建立了一个能够描述该部分流体稳态温度分布的数学模型，通过该模型可以给出升温结束点的位置，它为优化密度锁高度提供了理论依据。

Temperature distribution on steady state in density lock is simulated experimentally in this paper, temperature rising end point is discovered on the temperature curve on steady state. It separated conduction district and homoeothermie district. Only when temperature rising end point is in density lock, heat conduction can be restrained effectually. A mathematical model simulating temperature distribution is founded; Using the model location of temperature rising end point can be calculated. Theoretic evidence is provided for optimizing the height of density lock.
