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，从而为加热法测湿探针的设计及其在工程中的运用提供依据
A mathematical model of the flow field in the vicinity of the inlet of the humidity probe was set up by the heating method and the numerical simulation was conducted to analyze the measurement error caused by the non-equivalent kinetic energy sampling and the deviation of the flow direction from the axis, Needle design and its application in engineering provide the basis
