The topic of this article is a review of the approach to extract pressure fields from flow
velocity field data, typically obtained with particle image velocimetry (PIV), by combining the …

Obtaining real flow information is important in various fields, but is a difficult issue because
measurement data are usually limited in time and space, and computational results usually …

This paper explores the challenges associated with the determination of in-field pressure
from DPIV (digital particle image velocimetry)-measured planar velocity fields for time …

Efficient and well adapted algorithms are necessary to analyse the large number of vector
fields generated when observing time dependent flow fields. This paper discusses several …

We present an approach to particle image velocimetry based on optical flow estimation
subject to physical constraints. Admissible flow fields are restricted to vector fields satifying …

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 …

We present in this paper a novel combined scheme dedicated to the measurement of
velocity in fluid experimental flows through image sequences. The proposed technique …

The post-processing of the measured velocity in particle image velocimetry (PIV) is a critical
step in reducing error and predicting missing information of the flow field. In this work, time …

A numerical implementation of the advection equation is proposed to increase the temporal
resolution of PIV time series. The method is based on the principle that velocity fluctuations …

The analysis of complex fluid mechanical phenomena is based on experimental and
numerical analysis. Both approaches provide suitable data, but no complete and exactly …
