Research on two-phase flow instability in parallel inclined hollow conductors in the evaporative inner cooling power generator

With the rapid development of wind power, the application of evaporative cooling technology to wind power generators become a new research and application direction. In this paper, the instability in the inclined rectangular hollow conductors were studied through experiments and theoretical analysis, according to the design parameters of 2MW evaporative inner cooling wind power generator. Based on the equations of inclined parallel hollow conductors, analyze the dynamic instability. Taking the density wave instability in system with parallel conductors as an example got the occurrence condition. This provides a theoretical basis for system design.
