Optical flow estimation in experimental fluid mechanics

چکیده
We present in this paper a novel approach dedicated to the measurement of velocity in fluid experimental flows. Such information, which is fundamental for specialists, is usually computed by correlation methods on a special kind of images (named PIV). We present here a motion estimation technique which is based on an optical-flow extension. Results are presented on an experimental flow and are compared to those computed with standard methods of the fluid mechanics community.

Fluid experimental flow estimation based on an optical-flow scheme
We present in this paper a novel approach dedicated to themeasurementof velocity influid experimental flows through image sequences. Unlike most of the methods based on particle image velocimetry (PIV) approachesused in that context, theproposed technique is an extension of ‘‘optical-flow’’ schemes used in the computer vision community, which includes a specific enhancement for fluid mechanics ...
متن کامل9th International Symposium on Flow Visualisation, 2000 Adaptation of Standard Optic Flow Methods to Fluid Motion
In this paper, we address the problem of fluid motion estimation in image sequences. For such motions, standard dense motion estimation methods, based on intensity conservation and spatial coherence of motion field, are not suitable. This is due to the highly deformable nature of fluid medium. For all applications where fluid motions are to be recovered from images, it is then important to have...

متن کاملVariational Estimation of Experimental Fluid Flows with Physics-Based Spatio-Temporal Regularization
We present a variational approach to motion estimation of instationary experimental fluid flows from image sequences. Our approach extends prior work along two directions: (i) The full incompressible Navier-Stokes equation is employed in order to obtain a physically consistent regularization which does not suppress turbulent variations of flow estimates. (ii) Regularization along the time-axis ...
متن کاملMultivariate Jeffrey Fluid Flow past a Vertical Plate through Porous Medium
An analysis is suggested to study the impact of Hall currents in Jeffrey fluid which is chemically reactive through a porous medium limited by a semi-infinite vertical permeable plate within the existence of heat generation. An evenly distributed magnetic field turns vertically on the porous surface which absorbs the Jeffrey fluid with a changed suction velocity with time. The analytical expres...
