(31) "The key to mitigation is to establish a vortex wake consisting of two or more vortical pairs that are unstable and susceptible to rapid breakup, " he explains.

(32) With vortex model and circulation for free vortex of entrance flow solved, potential equation and stream function equation were derived.

(33) Combining momentum theory and vortex theory, rotor circulation equation was deduced. The rotor down-wash flow field was calculated using generalized down-wash flow model.

(34) The behaviors of vortex motion have been obtained with varying vortex density, varying pinning strength, and external Lorentz force.

(35) This technique is known as the vortex generator jet method of separation or stall control because it controls separation in the same general way as the well-known method using solid vortex generators.

(36) The essence is to realize the secondary purification by adopting the vortex chamber.

(37) Third, the MCV, the low tropospheric trough (vortex), and the hot towers conduct together the vertical uniformization between the lower and middle tropospheric systems through their interaction.

(38) The intelligence vortex flowmeter system is consisted of vortex sensor, temperature sensor, pressure sensor, LCD module and master controller, etc.

(39) The axisymmetric jet flow field is divided into jet flow area, unconcentrated flow, vortex flow area and impact area.

(40) The reverse flow and vortex can be detected at the downstream areas which cause the negative frequency components.

(41) In this article, the method of machining Blade profile of vortex - compressors on NC machine with linear - circular interpolation function is mentioned.

(42) The frequency of vortex increases with the augment of the casting speed, and decreases with the augment of the immersion depth and nozzle angle.

(43) According to the mechanism of pressure drop, vortex theory and the bed equivalent flow model were brought in.

(44) The adjustable eccentric weight can drive to the central line of main shaft through motor. Under the unstable state, it produces centrifugal force that makes raw material form vortex in the sieve.

(45) In this paper, the 3 D velocity fields in the furnaces' arch area for a conventional stock boiler and the model with dipole vortex device were measured by the hot wire aerometer.

(46) The obtained velocity vector distribution in the measured plane coincided with the flow visualization results under the same test condition. In addition these vortex flow field was analysed.

(47) Taking the advantage of numerical simulation that can simulate the different types of boundary conditions, the vertical vortex induced by the asymmetric initial flow is simulated too.

(47) Sentencedict.com is a online sentence dictionary, on which you can find nice sentences for a large number of words.

(48) The flow fields are different for the three phase motion patterns and there are two types of leading-edge vortex motion at an earlier stage of upstroke or downstroke.

(49) Its effect of dewater has bettered much than the traditional fixed vortex sieve.

(50) The vortex theory is adopted to study the side shrinkage angle and optimum step of the bulkhead gate to improve the overflowing condition.

(51) Inner vortex speeding cyclone dust collector can increase the dust collecting rate, decrease system resistance and prevent dust from adhering on the wall.

(52) The vortex pair induced by the separation is developing downstream into the wake of the after-body.

(53) The hydraulic characteristics of transverse axis vortex behind the sill of the dissipater are studied with the hydraulic test.

(54) The solitary wave theory of the weakly nonlinear, non-axisymmetric disturbances is used to model the spiral vortex breakdown.

(55) The notch filter is used first to remove the fixed strong disturbance, and then the spectrum analysis is employed to estimate the frequency of vortex signal.

(56) The valve structure is optimized to meet the need, which makes it have such advantages: Smaller vortex area and faintish vortex intensity, so the vibration of vortex is controlled efectively.

(57) The nonuniform induced velocity distribution on the rotor disk is derived from the fixed vortex theory.
