采用表面中心位置装有铜探头的平板,对射入大气环境的层流纯氩高温部分电离气体射流冲击平板的热流密度进行了动态测量,分析了测量条件对热流密度及其分布特性测量结果的影响.同时,研制了嵌有铜探头的小尺寸杆状热流探针,在小扰动条件下测量了射流的热流密度分布.结果显示层流等离子体射流具有稳定的能流密度,探针的移动速度对射流中心区域的热流密度测量结果影响很大. |

By using transient method, the heat flux distributions were measured for a partially-ionized high-temperature argon laminar-flow jet impinging normally on a flat plate, where a copper slug was embedded in the center of the plate as heat flux probe. The effects of measuring factors on the results were analyzed. A stick-shaped heat flux probe of lmm outer diameter was also designed to measure the heat flux distributions of the jet flow with small disturbance. Results show that the heat flux of laminar flow jet was stable, and sweeping velocity of the probe across the jet flow can affect the measuring result appreciably. |
