thermal stratification

基本解释

In thermal natural ventilation, buoyancy plumes derived from heating source make the thermal stratification indoors.
热压自然通风中，热源产生的浮力羽流使得室内存在热分层现象。
Obtains two kinds of quantity group based on the similitude principle i. e. the dimensionless similarity criterion and the dimensional thermal stratification height.
根据相似原理综合各因素得到了两种形式的综合量：无量纲的相似准则和热分层高度等量纲不为一的综合量。
According to the working principle of displacement ventilation system and domestic research, this paper studies the thermal stratification height of displacement ventilation system.
本文根据置换通风系统的工作原理，结合国内外置换通风发展的实际情况，详细研究了置换通风系统的热力分层高度及其影响因素。

热分层
Those two models are considered separately. Supply air velocity, heat power, the location of inlet vent and heat source; temperature efficiency and thermal stratification height are investigation to predict the ventilation effectiveness.
在这里，对两种模型分别考虑；首先从理论上分析得出影响房间气流流型、温度分布的重要影响因素：送风速度、热源强度、送风口位置、热源位置等；并把温度效率和热分层高度作为评价增益或抑制的重要指标。
