水平送风式和垂直送风式热风幕的计算,当前主要是根据设计经验,而没有考虑气流的不等温性对于气流速度变化的影响,若对于水平送风式空气幕其引力的作用能像某些文章指出的可以忽略的话,那么对于垂直送风式空气幕就可能导致较大的偏差。因此需要对气流的不等温性对于空气幕工作效能的影响程度和在通常垂直送风空气幕的计算中合理地考虑不等温性等问题进行探讨。
The calculation of horizontal air supply and vertical air supply hot air curtain is mainly based on design experience and does not consider the influence of airflow’s non-isothermality on the change of airflow speed. If the effect of gravity on horizontal air supply air curtain is Some articles point out to be negligible, then the vertical air curtain may cause large deviations. Therefore, it is necessary to discuss the influence of the non-isothermality of the airflow on the work efficiency of the air curtain and the reasonable consideration of the non-isothermality in the calculation of the normal vertical supply air curtain.
