Sentence examples for unsteady term from inspiring English sources

The theoretical model proposed allows the pressure variation to be split into two contributions, a quasi-steady term and an unsteady term with a simple physical meaning.

In this case, the unsteady term in the diffusion equation (Eq. (7)) can be neglected, because diffusion is fast enough to establish a steady-state concentration distribution of volatiles in the melt.

The former unsteady term could become comparable in magnitude to the latter steady term when the wall moves quick enough to produce a considerable wall motion-induced flow that is distinct from the steady flow determined by the static geometry of the channel.

A numerical scheme including pseudo-unsteady terms is developed to calculate the optimal solution in an ideal earth dam cross section to be designed utilizing two different types of soil material.

It is found that the unsteady curvature term dominates over the steady curvature term in flame stretch and that the flame propagation speed correlates well and decreases with flame stretch.

The proposed model considers the unsteady friction term and comprises the continuity and momentum conserve equations, which are solved by the method of characteristics.

The study also assesses the impact of a semi-implicit treatment of the unsteady source term associated with the discretization of the physical time-derivative of the governing equations on the numerical stability of the explicit multigrid integration.

A novel distribution scheme of the unsteady-fluctuation term, coupled with a new limiting procedure for hampering spurious extrema, are the key-ingredients of the remarkable accuracy of the new method, which is applied with success to both scalar advection problems and unsteady inviscid flows in two space dimensions.

The shell is modelled by Donnell's nonlinear shell theory, retaining in-plane inertia and geometric imperfections; the fluid is modelled as a potential flow with the addition of unsteady viscous terms obtained by using the time-averaged Navier Stokes equations.

This constraint on the time step allows the containment of the amplification of capillary waves along the interface and puts more emphasis on the terms linked with the density in the Navier Stokes equation (i.e. unsteady and inertia terms) rather than on the viscous terms.

Hancock experimental data was used for curve fitting the unsteady aerodynamic damping term as a function of frequency.
