A three-segment electrodiffusion probe in axisymmetric flow with stagnation and separation
- 24 Downloads
Calculation is presented of the influence of the normal velocity component on the directional characteristics of a three-segment electrochemical probe in the vicinity of a stagnation or a separation point. The results obtained here for a 2D flow corresponding to an axisymmetric flow having a stagnation point show quantitative differences, especially in the stagnation region, with respect to an earlier calculation performed on a 2D flow corresponding to a planar flow having a stagnation line. An experimental study with such a probe is then reported which demonstrates the possibility of this arrangement in the stagnation region of an immersed jet.
