WebThis paper presents new analytical solutions for the critical velocity for smoke control in tunnels and cross-passages. These analytical solutions for the critical velocity dispense with the need to solve for two coupled non-linear equations, and avoid the drawbacks associated with iterative approaches to solving for such equations. WebFinally, the Fourier Maximum Angle Analysis (FMAA) is used to filter out the noise further and obtain the clear orientations to achieve the measurement of velocity and discharge. The experimental results show that, compared with the widely used image velocimetry measurements, the accuracy of our method in the average velocity and flow discharge …
