Water Surface Velocity Measurement Using Pattern Matching Technique
نویسندگان
چکیده
In many cases it is necessary to measure the velocity of water flow whether it is during some installation of scientific research or some natural calamities. But, In surface water studies, it is difficult to measure the velocity of water. Contact Sensors have been used in various examination but they did not execute accurate result. In this paper non-contact velocity measurement technique based on Particle Image Velocimetry (PIV) is implied. For this purpose the video of water surface is taken by a fixed digital camera. The undistorted appearances are collected. Spatial cross correlation method is applied as the pattern matching technique to calculate the displacement. The measurement is done on the hydraulic model of CWPRS and the results are shown.

Numerical Simulation of Flow Pattern around the Bridge Pier with Submerged Vanes
Bridges are very important for establishing communication paths. For this reason, it is important to control scour around bridge piers. Several methods have been proposed for scour control. One of the most useful methods is the use of submerged vanes. In the other hand, laboratory circumstances force many considered effective factors to be skipped in the scour phenomenon. In this situation, the...
متن کاملSimultaneous measurement of water flow velocity with fluorescent and speckle imaging technique
The average velocity of water flow has been simultaneously measured with fluorescent and speckle imaging methods. The measured velocities with two methods are in good agreement with each other and it confirms that the speckle imaging method can be used as a confident method to measure the velocity of water flow in a dry leaf. Also the velocity of water flow through thick and thin xylems of a le...
متن کاملEffect of Crest Roughness on Flow Characteristics over Circular Weirs
Different construction materials with different roughness used to make circular weirs highly affect surface roughness and, in turn, flow hydraulics passing over these structures. In the present research, numerous experiments under different hydraulic conditions were performed on a physical model to study the effects of roughness on flow hydraulics over a circular weir. The flow hydraulics incl...
متن کاملAltitude measurement using laser beam reflected from water surface
In this paper altitude measurement from water surface using laser beam is presented. Research data indicate that the reflection of infrared waves from water surface is about zero and it is less than 2% for visible radiations. Phase-shift and heterodyne technique was used for the measurement, and the laser beam ( mW p nm 10 , 700 = = l ) was modulated by a sine wave having a fixed frequency....
متن کاملFlow Variables Prediction Using Experimental, Computational Fluid Dynamic and Artificial Neural Network Models in a Sharp Bend
Bend existence induces changes in the flow pattern, velocity profiles and water surface. In the present study, based on experimental data, first three-dimensional computational fluid dynamic (CFD) model is simulated by using Fluent two-phase (water + air) as the free surface and the volume of fluid method, to predict the two significant variables (velocity and channel bed pressure) in 90º sharp...
