The design of the coaxial mixers depends on many interrelated parameters including the geometry and dimensions of the mixing vessel, the location and type of the impellers, speed ratio, impeller diameter, rotation mode, and fluid rheology.
The present study employs the tool of computational fluid dynamics to simulate a two-phase solid liquid flow in an annulus based on the analysis of cuttings concentration, pressure drop profiles, axial fluid, and solid velocities as a function of several drilling parameters: drill pipe eccentricity, inclination, drill pipe rotation, ROP and fluid rheology.
The dynamic type of compressor may be subdivided into the centrifugal type (with flow through a rotating runner or rotor primarily in a radial direction), the axial-flow type (with flow through a runner primarily in a direction parallel to the axis of rotation), and the fluid-jet type.
An important limitation of the DEM CFD code is that fluid shear stress does not affect particle rotation, and non-Newtonian fluids cannot as yet be modeled.
Based on this rule, a fundamental concept is presented for designing split-and-recombine mixers that performs 180° rotation of fluid interface, and possible channel configurations composed of 3D bent channels are proposed.
Hardebeck (2012) observed that M ≥ 8 subduction zone earthquakes in zone B generally exhibit stress rotations, while those in zone C generally did not, potentially linking stress rotations to both radiated energy and fluid pressure.
Thus, the objective of this study is to discuss the effect of rotation on fluid flow and heat transfer performance of turbine blade similar U-shaped channel with the combination structure of ribs, dimples or protrusions.
Dilation associated with thermal expansion and fluid production leads to rotation of the principal stresses around fluid source regions.
We assumed that the detached area and the opening angle are influenced by the degree of humeral rotation and the amount of intraarticular fluid.
The first one is through introducing secondary flows in the vicinity of the conducting surface using metal foam guiding vanes, which are fixed obliquely and rotating coaxially to trap fluid particles while rotation and then force them to flow over the conducting surface.
