Compression zone effect in batch sedimentation

AIChE Journal, 1988
AbstractTheories of batch sedimentation, taking into account the compression zone effect, are reinterpreted and modified. According to the discussion presented and the experimental results shown, characteristics—which are the loci of points representative of layers with the same settling rate and the same solids concentration in the settling zone—rise ...

The development of compression damage zones in fibrous composites

Composites Science and Technology, 2001
Recent experimental work (Narayanan S, Schadler LS. Mechanisms of kink band formation in graphite/epoxy compsites: a micromechanical experimental study. Comp Sci Technol 1999; 59:2201-13) suggests that kink bands in unidirectional continuous carbon fiber reinforced polymer composites initiate from damage zones formed under axial compressive loads.

Zone Settling and Compression

2017
Sludge settling characteristics are discussed. Theories of zone settling and compression are presented. The theory is applied to the design of thickener in continuous operation. Design problem is solved in the way of illustration.

Zones of influence in the compressible shear layer

Fluid Dynamics Research, 1993
The effect of Mach number on communication between regions of a shear layer is analyzed in the limit of geometric acoustics. Communication is quantified in terms of the acoustic intensity emitted by a point source and received by an observer moving with the flow.

Compression Storage of Images With an Effective Annular Zone

2009 Third International Symposium on Intelligent Information Technology Application, 2009
In 3D measurement of complex deep-hole inner profile with ring-structured-light, the effective area of the original images is an annular zone, only a small portion of the whole. A new image compression storage method has been proposed, where only the image information of the effective annular zone, denoted by T, is stored.

Diffusion across a laminar compressible mixing zone

International Journal of Heat and Mass Transfer, 1967
Abstract The problem considered in this paper is the laminar mixing of two parallel streams of compressible fluid mixtures. The streams are two component compressible fluids, e.g. air and some contaminant. The primary interest is to describe the mixing process and its effect on the concentration of each species composing the fluid.

Rectangular Stress Block for Nonrectangular Compression Zone

ACI Structural Journal, 1995
Tests of 19 beams made with high-strength concrete showed that use of the current ACl rectangular stress block was conservative for semicircular compression zones, but slightly unconservative for triangular compression zones. Concrete strengths f c ' were 9630, 12,800, and 14,830 psi (66.4, 88.2, and 102.2 MPa).

Calculation of the compression zone height in continuous thickeners

AIChE Journal, 1990
Abstract A method to calculate the compression zone height in continuous thickeners is presented. With this method, it is necessary to know the variations of the pulp‐supernatant interface and the sediment height vs. time in a batch test.

Phenomenon of crack arrest in a plate with transverse compression zones

Strength of Materials, 1978
This paper describes the results of an experimental investigation of crack retardation and arrest in a zone with compression stress applied to the plate in a direction normal to its plane. Within the applicability of linear elastic fracture mechanics, this phenomenon can be associated with changes in the stress intensity factor KI at the crack tip of a
