  • Fluid analysis method and fluid analysis system
    Patent number: 9140641
    Abstract: A fluid analysis method is provided. A gradient distribution of a first scalar property of a calibration fluid in a space is obtained. A calibration schlieren image of the calibration fluid is acquired and processed to obtain an intensity distribution of the calibration schlieren image. The gradient distribution of the first scalar property of the calibration fluid in the space is mapped to the intensity distribution of the calibration schlieren image, so as to obtain a corresponding relation between the gradients of the first scalar property and the intensities. A test schlieren image of a test fluid is acquired and processed to obtain intensity distribution of the test schlieren image. The intensity distribution of the test schlieren image is converted to the gradient distribution of the first scalar property of the test fluid according to the corresponding relation. Moreover, a fluid analysis system is also provided.
