Sentence examples for fluctuations field from inspiring English sources
The experimental set-up has been designed to reproduce a pressure fluctuations field beneath a turbulent boundary layer as close as possible to those in flight.
Turbulence generation methods allow the initialization and up-keeping of the velocity fluctuations field to promote the observed/needed turbulence in the flow.
In order to synthetically produce the unsteady inlet condition, a divergence-free and spatially correlated fluctuations field is generated by means of the Modified Discretizing and Synthesizing Random Flow Generator technique.
This model has three main components: (1) prediction of mean flow quantities by solving the 3D Navier Stokes equations using the standard k ε model with Kato and Launder modifications; (2) generating a synthetic turbulent velocity field using a stochastic model and finally (3) solving the Poisson equation that governs the pressure fluctuations field.
It is assumed that a given molecule changes orientation of its nearest neighbours through the fluctuation field.
