温度相关法测量柴油机排气流量

Temperature Correlation Measurement in Diesel Gas Flow

对管内流体流量的温度相关测量法进行了理论分析,并对柴油机排气温度脉动信号进行相关处理,得出相关流量。与毕托管测得流量相比较,表明该方法具有较高测量精度,实时性强,简单可靠。

The theoretical analysis is performed for in tube flow measurement by correlation methods, and the correlation flow is obtained from analyzing stochastic temperature signals of diesel gas. Compared to dynamic tube, it is show that this method offers high accuracy with wide measuring ranges. The measurement system can be realized easily on computer and microprocessor.
