Sentence examples for fluid superficial from inspiring English sources

In this context, the transient behaviour of the two systems considered in response to changes of fluid superficial velocity is analysed, allowing to validate the capability of the numerical model to capture the propagation of voidage shocks along bed height.

Capabilities of the proposed synthesis and its effectiveness are supported by numerical studies made for three coupled systems with distinct diffusivity parameters and for underactuated linearized dimensionless temperature-concentration dynamics of a tubular chemical reactor, controlled through a boundary at low fluid superficial velocities when convection terms become negligible.

Replicated series of experimental runs were performed to study the effects of residence time on hydrogen evolution rate and to characterize the critical conditions for the wash out, as a function of the inlet glucose concentration and of the fluid superficial velocity.

Treatment involves injection of up to 100 ml fluid, superficial to the pectoral muscle and deep to the glandular breast disc, and is semipermanent, usually only lasting up to 1 year before a top-up injection is required.

The Brinkman equation is as follows [ 16]: (1) μ ∇ 2 u s − μ k u s = ∇ p,     ∇ u s = 0, where k the permeability of the porous medium, u s denotes the fluid superficial velocity vector, p the fluid pressure, and μ is the effective viscosity in the porous medium.

With the exception of rotational Reynolds numbers (Reθ) close to the critical value, downstream displacement of vortices was slower than the fluid's superficial velocity.

The effect of mixture flow velocity and fluid phase superficial velocity on the droplet dynamics in vertical and horizontal pipes is investigated numerically.

This work presents a lumped-parameter model of this system that uses empirical values of the vortex drift velocity, Vd (the ratio between the speed of the vortex core and the fluid's superficial velocity).

Development of a direct methanol fuel cell (DMFC) mass flux model, using conventional transport theory, is presented and used to predict the fluid phase superficial velocity, methanol and water molar fluxes, and the chemical species (methanol and water) dimensionless concentration profiles in the polymer electrolyte membrane, Nafion® 117, of a DMFC.

ICs have been located in the synovial fluid, the superficial layers of the cartilage and circulating in the periphery [ 1- 3].

Magnesium phases are excluded intentionally, since dilution of geothermal fluids with superficial, Mg-rich waters will significantly bias reservoir temperature estimations, by overestimating equilibration temperatures for magnesium minerals.
