风流经过风桥时连续转弯,能造成较大的局部阻力。研究合理的风桥结构型式,降低风桥阻力,对改善通风状况和节约能源很有现实意义。 1981年,东北工学院通风研究室对几种不同结构型式风桥的阻力进行了对比实验。现将初步结果简介如下。实验是在薄铁板制成的正方形模型巷道
Wind flow through the wind bridge continuous turn, can cause greater local resistance. To study reasonable wind bridge structure type and reduce wind bridge resistance has great practical significance for improving ventilation and saving energy. In 1981, Northeastern Institute of Technology Ventilation Laboratory of several different types of structural resistance of wind bridges were compared experiment. Now the preliminary results are as follows. The experiment is a square model roadway made of thin iron plate
