结果表明，螺旋折流板换热器管间流体斜向冲刷管束。
The experimental results show that the fluid flow in tube bundles is angled to the tubes.
而平台区由于设计管径仅为潮汐通道区的三分之一，其极限冲刷长度远小于潮汐通道区。
Because the pipeline diameter in platform is one third of that in tidal channel, so the limit scour length is less.
本文还通过计算机计算，得知流体对弯管两侧的冲刷力也是振荡的。
By using computer to calculate, we find the fluid flush on the curved pipe wall is also oscillatory.
认为炉内火焰冲刷水冷壁及对流过热器烟温分布不均是造成爆管的主要原因。
It is found that the main cause of tubes bursting is the flame in the burner washing down watercooled wall and the uneven distributed flue-temperature over the convection superheater.
前言：河流穿越管道冲管段主要是在管道露出河床的基础上，由于冲刷现象使管底“淘空”而形成。
Because the pipeline fundus is "hollowed out" by the scouring phenomena, the scoured pipeline is formed.
本发明涉及连续铸钢用保护管，它以一般连铸用耐火材料基础复合陶瓷材料经过混料、成型、热处理等工序制作，所得产品具有耐冲刷、抗腐蚀及较好的热稳定性等特点。
The protecting pipe for continuously-casting steel is made up by using general refractory material as basis and adding ceramic material through the processes of mixing, forming and heat treatment.
