半横向通风 meaning in Chinese
semi-transverse ventilation
Examples
- According to the ventilation theory of highway tunnel , the paper deduces the calculating equations of longitudinal ventilation , semi - transverse ventilation and transverse ventilation
本文首先依据公路隧道通风理论，系统地推导了纵向通风、半横向通风和全横向通风三种通风方式的计算公式。 - The work here has a lot of application and stringency . for the first time , the various ventilating methods and effects to control the smoke in a fire emergency of the erlang mountain tunnel semi - transient ventilation road tunnel are presented . with the hypothesis of one - dimensional steady ideal fluid , the experimental and numerical studies are presented
本文首次研究了半横向通风方式的隧道在发生火灾时，通过通风系统的风机、横通道及平行导洞内的阀门的不同动作方式在着火点产生大于临界风速的强制气流，对隧道内烟气走向进行控制的各种方法和效果。 - Computational fluid dynamics ( cfd ) techniques are used to study and understand fluid behavior in tunnels . by simulating complex specific operational cases , we can educe velocity or flux distribution in tunnel under different ventilation and resistance situation and determine the favorable operational procedures of the erlang mountain tunnel ventilation in a fire case . comparison has been made between a simulation and experiment for some cases in order to prove the cfd model is powerful , so that enables the study of cases for which experimental data is not available
采用本文将隧道内的气流看成是理想流体的一维恒定流动，通过对二郎山特长公路隧道半横向通风系统建立隧道内的空气动力学模型，利用计算机进行数值分析与计算，得出发生火灾时，不同通风阻力条件下隧道中的风速分布及流量分布，并通过实验室隧道模型实验进行验证与修正，依据研究结果给出了二郎山半横向通风隧道的火灾控制方案，从而解决了二郎山公路隧道通风对火灾的控制问题，同时为半横向通风公路隧道的火灾通风提供科学的方法。
