Results indicate that the characteristics of cavity flowfield were altered similarly by gas and liquid injection. The local boundary layer or shear layer are modified by injection on upstream/bottom wall of cavity, and the cavity shear layer immediately becomes angled with respect to the main flow direction.
The results obtained show that the flow and heat transfer performance changes significantly in the entry region and this change disappears basically after the fourth cell number along the main flow direction.
The main orientation of theoretic research should be on the analysis of influential relationship between disaster and each factor based on field flow method, and the emphases is on the general law such as disaster mechanism and coupling among multiple disasters.
So the concept of the EPM(Enterprise Project Management) become the mainstream direction and management technology of the development and management for this kind of company.
Cluster technology has become the mainstream direction for high performance calculation, and the quality of cluster resource management system directly affects the performance of cluster system.
At present,our country corporate management reform development mainstream direction still is becoming an information based society,less levels of management,automation,systematization,internationalization and so on,the very few enterprises will manage 'the green' direction to bring into line with the strategy which the enterprise will develop to come up highly truly.
Develops the highway information visual system using the WebGIS technology can enhance the system the operating efficiency,strengthen the massive spatial data and attribute data handling ability. Simultaneously it overcame the malpractice of developing this system based on the traditional pattern. and it will certainly become the mainstream direction of GIS development in future.
In the mainstream direction of Marxist humanity molding, main contents of humanity molding are grasped and in time human spirits will be enriched and fulfilled, human relationship more harmonious and society more peaceful, stable and beautiful.
PVC resin with high bulk density is the main direction for producing the special PVC for pipe with great diameter, spherical PVC hasn't ever been produced wholesale.
Results are presented on film cooling by homogeneous injection into a turbulent boundary layer through porous inserts of various lengths along the main flow direction.
The winglet area was small compared to the fin area, it formed an angle with the main flow direction, so that the leading edges generated strong longitudinal vortices.
For a given geometry of the corrugated plates the geometrical characteristics of the undulated plates, the angle formed by the latter with the main flow direction, and the Reynolds number were made to vary.
Heat transfer distributions are presented for a rectangular duct with two opposite wide walls arranged with V-shaped ribs pointing upstream or downstream relative to the main flow direction.
The periodicity of the columnar patterns was assessed along trajectories perpendicular to the main orientation of the bands and differed in the two columnar systems.
The main orientation of the bands in both columnar systems is related to a) the representation of the vertical meridian, b) the anisotropy of the cortical magnification factor, and c) the tangential spread of intracortical connections.
Below transition: The main orientation of the polymer matrix is parallel to the normal of the cuticle and the main orientation of the layer with soluble lipids is perpendicular to the normal.
Synthesis of compounds containing a fragment similar to the guanidine group of L-arginine, which is a substrate of nitric oxide synthase (NOS), is the main direction in creating NOS inhibitors.
Synthesis of compounds containing a fragment similar to the guanidine group of L-arginine, which is a substrate of nitric oxide synthase (NOS), is the main direction in creating NOS inhibitors.
The main direction of transformation of acyclic alcohols is formation of complexes with no alkyl substituents at the central carbon atom of the allyl ligand; with cyclic alcohols, exocyclic complexes are formed.
In dealing with the problem of sand particles moving relative to the surrounding water, Stokes' formula of resistance has usually been used to render the velocity of sedimentation of the particles. But such an approach has not been proved rigorously, and its accuracy must be carefully examined. In the previous paper, we gave the resistance acting on a sphere moving in a non-uniform flow field. In this paper, we assume the concentration of sand particles to be very small, and using the previously obtained fo...
In this paper the three-dimensional equations for calculating incompressibleviscous flow in a straight compressor cascade with circular arc blades are presented.The calculation which is carried out using these equations requires a coordinatesystem as input to define primary and secondary flow directions.In connectionwith this cescade an orthogonal curvilinear system has been given out.The laminarincompressible viscous flow in a compressor cascade can be predicted by the use ofthese equations parabolized in ...
In the inflorescence of Festucoideae, there are series composing ofthree typical forms (Panicle-raceme-spike) and their intermediate. Theyhint some evolutionary lines. The ecological changes arising in specieswith panical inflorescence and the atavism happening in specis withspike show that reduction may be the main tendency of the inflorescen-ce' evlution in this subfamily. The spike of Triticeae may be derived fromradiate panicle and racemose inflorescence of Bromeae. They have the dire-ction of spikelet ...
