A Hybrid PIV/Optical Flow Method for Incompressible Turbulent Flows

Autor: Luís P. N. Mendes, Ana M. C. Ricardo, Alexandre J. M. Bernardino, Rui M. L. Ferreira

Publikováno v: Water, Vol 16, Iss 7, p 1021 (2024)

We present novel velocimetry algorithms based on the hybridization of correlation-based Particle Image Velocimetry (PIV) and a combination of Lucas–Kanade and Liu–Shen optical flow (OpF) methods. An efficient Aparapi/OpenCL implementation of thos

A Web GIS Platform to Modeling, Simulate and Analyze Flood Events: The RiverCure Portal

Autor: Alberto Rodrigues da Silva, Jacinto Estima, Jorge Marques, Ivo Gamito, Alexandre Serra, Leonardo Moura, Ana Margarida Ricardo, Luís Mendes, Rui M. L. Ferreira

Publikováno v: ISPRS International Journal of Geo-Information, Vol 12, Iss 7, p 268 (2023)

Flood events are becoming more severe, causing significant problems to human communities, including physical, psychological, and material damage. For both flood forecasting in emergency response situations and flood mapping, georeferencing and data c

Drag on a Square-Cylinder Array Placed in the Mixing Layer of a Compound Channel

Autor: Rui M. L. Ferreira, Miltiadis Gymnopoulos, Panayotis Prinos, Elsa Alves, Ana M. Ricardo

Publikováno v: Water, Vol 13, Iss 22, p 3225 (2021)

There are no studies specifically aimed at characterizing and quantifying drag forces on finite cylinder arrays in the mixing layer of compound channel flows. Addressing this research gap, the current study is aimed at characterizing experimentally d

Experimental Investigation of the Flow Field in the Vicinity of an Oscillating Wave Surge Converter

Autor: Moisés Brito, Rui M. L. Ferreira, Luis Teixeira, Maria G. Neves, Luís Gil

Publikováno v: Journal of Marine Science and Engineering, Vol 8, Iss 12, p 976 (2020)

The main objective of this paper is to characterize the flow field on the front face of an oscillating wave surge converter (OWSC) under a regular wave. For this purpose, the longitudinal and vertical velocity components were measured using an Ultras

The Logarithmic Law of the Wall in Flows over Mobile Lattice-Arranged Granular Beds

Autor: Federica Antico, Ana M. Ricardo, Rui M. L. Ferreira

Publikováno v: Water, Vol 11, Iss 6, p 1166 (2019)

The purpose of the present paper is to provide further insights on the definition of the parameters of the log-law in open-channel flows with rough mobile granular beds. Emphasis is placed in the study of flows over cohesionless granular beds compose
