Sentence examples for stationary bed from inspiring English sources

Special emphasis was put on the range of low mixture flow rates, where a stationary bed is expected.

When drilling long horizontal wells, drilled solids tend to settle down on the low side of the wellbore and form a stationary bed.

The critical sand deposition velocity is defined as the minimum velocity that keeps all particles moving at all time, above which there is no stationary bed at all.

The model is developed by considering fluid flow over a stationary bed of solid particles of uniform thickness, which is resting on an inclined pipe wall.

The formulations adopted yield realistic instantaneous vertical profiles of velocity and sediment concentration from the stationary bed, through the high-concentration sheet-flow layer up into the outer suspension layer.

This paper presents a theoretical analysis of the problem of cuttings transport for a two-region system composed of a fluid bed (ω-region) and a stationary bed of drill cuttings, which is considered as a porous medium (η-region) in the two-phase system.

Deposition velocity is the velocity below which particles begin to deposit forming moving or stationary beds at the bottom of the pipe (Poloski et al. 2009a, b; Yokuda et al. 2009; Turian et al. 1987; Peysson 2004; Doron and Barnea 1996; Ibarra et al. 2014).

The main transport mechanisms of proppant particles are settlement and fluidization, which cause a three-layer flow pattern (stationary proppant bed, fluidization layer and clean fluid layer) to form.

Pure drilling fluid region, dispersed layer, and stationary cuttings bed are emerged in low rotary speed or flow rate.

The first approach assumes that the gasification occurs on a stationary coal bed and that the coal seam as a highly permeable porous medium, in which bed properties change with reactions (Magnani and Farouq 1975; Thorsness and Kang 1985; Biezen and Bruining 1995).

The nuclei were produced by dropping the binder solution onto a stationary powder bed.
