本研究是在开展模拟涂层裂纹或未裂纹时的MHD压降实验研究时同时测量的裂纹电极间的MHD电位变化情况。实验段见文献[1]中的图1所示结构。用△V_(14)、△V_(24)分别表示余裂纹电极D1和D2与参考电极D4间实验测得的电位差,此处只选出具有一定代表性的电极间的电位差随雷诺数Re的关系曲线,即Re—△V_(14)和Re—△V_(24)的实验曲线,其结果见图1～3所示。
The present study is a simultaneous measurement of the MHD potential changes between cracked electrodes at the same time of MHD pressure drop experiment to simulate coating crack or crack. Experimental paragraph see [1] in the structure shown in Figure 1. △ V_ (14) and △ V_ (24) are respectively the experimentally measured potential differences between the residual crack electrodes D1 and D2 and the reference electrode D4, where only the representative potential difference between the electrodes is selected as the Reynolds number Re relationship curves, that is, Re- △ V_ (14) and Re- △ V_ (24) experimental curve, the results shown in Figure 1 ~ 3.
