Abstract:

The experimental investigation of the thermal stratification of a single buoyancy source in the natural displacement ventilated room was reported.The bubble plume model was adopted to simulate the thermal stratification in this project.The varied relationships between the effective ventilated area and the height of the thermal stratification have been discussed.The testing data obtained from the analysis of the INSIGHT 3G software were compared with the calculated results of the mathematical model and it was found that the non-dimensional height of the thermal stratification increased with increasing non-dimensional effective ventilated area within the natural displacement ventilated room driven by a single point heat source.The height of the thermal stratification of the single point heat source is the function of the non-dimensional effective ventilated area.

摘要：

通过气泡羽流模型，对具有单一浮力源的室内自然置换通风热力分层高度进行了模拟实验研究，讨论了有效通风面积与热力分层高度之间的变化关系。将通过INSIGHT 3G软件获得的实验数据与数学模型进行了对比分析，发现自然置换通风室内单一点源热力分层的量纲1高度随着量纲1有效通风面积的增加而增高，室内自然置换通风单一浮力源的热力分层高度仅是其量纲1有效通风面积的函数。
