加热法测量湿度探针取样过程的数值模拟与分析

Numerical Simulation and Analysis of the Sampling Process of Wetness Measurement Probe through the Use of a Heating Method

建立了加热法测量湿度探针进口附近区域流场的数学模型，并通过对其进行数值模拟来分析由于非等动能取样及汽流方向偏离轴线所造成的测量误差。

A mathematical model has been set up for a region near the inlet of a heating method based wetness measurement probe. By way of a numerical simulation an analysis was conducted of the measurement error due to a non isokinetic sampling and an axial deviation in the steam flow direction. The results of such an analysis provide useful data for the design and engineering application of the heating method based wetness measurement probes.
