| 摘 要： | 针对汽轮机低压汽缸排汽处于湿蒸汽状态下,等温线和等压线重合而无法测量确定焓值的情况,利用M ie电磁波散射理论计算出了激光散射的相函数。同时,计算了复折射率虚实部以及偏差对相函数的影响。通过光电探测技术和相函数的反演拟合,可确定出凝结水粒子分布函数和最可几半径、平均半径以及最大半径,积分后可以计算出液态水的含量。气相部分通过压力和温度的测量和理想气体状态方程计算出干蒸汽密度,从而计算出湿蒸汽的干度。

| Abstract: | A phase function of laser light scattering has been calculated based on Mie electromagnetic wave scatter theories aiming at case of undetermined enthalpy because of superposition between isotherm and isobar when low-pressure cylinder of turbine works in wetness vapor.An influence of real and imaginary warp of complex refractive index on phase function has been considered.The most probability radius,average radius and the large radius can be calculated by photo-electric technology and the method of reverse simulation,and content of liquid water can be obtained by integral calculation.The vapor density can be calculated by measuring pressure and temperature combining with ideal gas state equation.And the steam wetness can be accounted. |
