The Lévy fractional Brownian motion family as a new paradigm in the modeling of turbulent wave-front phase
(Society of Photo-Optical Instrumentation Engineers, 2007-09-25)
In Perez et al. [J. Opt. Soc. Am. A 21 (10), 2004] we have given a general formalism to model the turbulent wave-front phase by using fractional Brownian motion processes. Moreover, it extends classical results to non- ...
Influence of particle mass fraction over the turbulent behaviour of an incompressible particle-laden flow
(MDPI, 2021-10-21)
The presence of spherical solid particles immersed in an incompressible turbulent flow was
numerically investigated from the perspective of the particle mass fraction (PMF or φm), a measure
of the particle-to-fluid mass ...
Hydraulic characterization of turbulent flow drippersCaracterização hidráulica de gotejadores de fluxo turbulento
(2018-05-15)
In the evaluation of hydraulic performance of four models of not self-compensating drippers was used a bench of tests with capacity for 25 drippers of each model. Each model was subjected to different pressures (p), thus ...
Bayesian Estimation of Turbulent Motion
(IEEE Computer Society, 2013-04)
Based on physical laws describing the multiscale structure of turbulent flows, this paper proposes a regularizer for fluid motion estimation from an image sequence. Regularization is achieved by imposing some scale invariance ...

(Colombia, 2019-01-22)
Se realizó un análisis computacional, mediante la técnica del CFD, del perfil NACA 2415, con los modelos de turbulencia Realizable K-ε y el modelo de turbulencia K-ω SST para obtener sus curvas aerodinámicas. El software ...
Physical–numerical parameters in turbulent simulations of natural convection on three-dimensional square plates
(2022-01-05)
Purpose: This paper aims to study, experimentally validate and select the main physical and numerical parameters of influence in computational numerical simulations to evaluate mean heat flux by natural convection on square ...
Financial modelling in turbulent scenarios: A didactic for the financial valuation of companies and projects
(Cartagena de Indias, 2022)
The actual professional needs to process large volumes of real information from companies and projects, to test and to validate various solution scenarios for the most successful decision making in difficult situations. ...
