| 摘 要： | 利用超声波在空气中的传播速度会随着空气温度的变化而变化这一特点,可测得空气中不同温度下的平均速度场,进而重建空气中的温度场。提出了一种非对称布置超声波传感器重建二维温度场的方法,在被测温度场周围布置8个收发一体的超声波传感器,并将被测温度场划分为24个小区间,以得到超声波通过每个小区间的平均温度值,以该温度值作为小区间中心点的温度并进行插值,从而重建整个被测区域的温度场。

| Abstract: | A temperature field related to ultrasonic wave propagation in the air according to the different velocities can be reconstructed.A method of two-dimensional temperature field reconstruction has been proposed in this paper.The temperature of the total temperature field has been calculated applying the method of two-dimensional interpolation according to the temperature values measured by 8 ultrasonic sensors which are both the transmitters and receivers distributed around the measured field with given positions in the experiment. |
