A method based on the mixed potential theory is put forward to determine the polarization state of the metal with the middle potential in tri‐metals galvanic couple. The potential distribution and current density distribution of the complicated galvanic couple composed of AA5083, 20# steel, and H62 copper alloy were simulated by finite element method, and the effect of configuration position on the...
It is well known that increasing the rotational velocity is an effective way to increase the total pressure ratio. With increasing flow velocity especially under the condition of transonic flow in the supersonic region, where exist strong shock waves, the shock wave loss becomes main and important. Simultaneously, there occurs boundary layer separation due to the shock wave / boundary layer interaction...
