Experimental and numerical study of nonlinear dynamic behaviour of an aerofoil [PDF]

open access: yes, 2014
The paper describes the experimental and numerical investigations on a plunge-pitch aeroelastic system with a hardening nonlinearity. The goals of this work are to achieve a better understanding of the behaviour of the model while it undergoes Limit ...

Vorticity moments in four numerical simulations of the 3D Navier–Stokes equations [PDF]

open access: yes, 2013
The issue of intermittency in numerical solutions of the 3D Navier–Stokes equations on a periodic box [0,L]3 is addressed through four sets of numerical simulations that calculate a new set of variables defined by Dm(t)=(ϖ−10Ωm)αm for 1≤m≤∞ where αm=2m ...

The Module Gradient Descent Algorithm via L2 Regularization for Wavelet Neural Networks

open access: yesAxioms
Although wavelet neural networks (WNNs) combine the expressive capability of neural models with multiscale localization, there are currently few theoretical guarantees for their training.

Vibrations of the three-layer shell with damping

open access: yesEngineering Transactions, 2006
In this paper the analytical method [17–18] has been used for solving the problem of vibrations of the three-layer shell with damping. External layers are modelled as the MINDLIN shells and the internal layer possesses the characteristics of a ...

Numerical simulation of rivulet evolution on a circular cylinder in an airflow

open access: yes, 2008
On wet and windy days, the inclined cables of cable-stayed bridges may experience a large amplitude oscillation known as Rain-Wind-Induced Vibration (RWIV).

Two-dimensional numerical experiments of convection.

open access: yes, 1996
PhDI report the results of numerical studies of 2-dimensional fully compressible convection of a fluid in which the dependence of the radiative conductivity on temperature T is taken as K, (V + aT -5)1 so that central regions of the layer are unstable ...

Numerical investigation of boiling [PDF]

open access: yes, 2012
In this work, we study different phenomena that occur during nucleate boiling. We numerically investigate boiling using two phase flow direct numerical simulation based on a level set / Ghost Fluid method.
