A two bladed dual direction impeller includes blades that each has an inner blade portion (20) that forces material in a first direction and a second blade portion (24) that forces material in a second direction opposite to the first direction. The first and second blade portions are radially...
ahowever her parents always kept her inside the house。the pretty parrot was ignorant。whenever someboby calls out for her,she would play out withthe visitor。she used to forget her mother‘s advice to stay away from the strangers 然而她的父母总保留了她在房子里面。俏丽的鹦鹉是无知的。每当so...
The global displacement vector q contains two translational (in the x and y directions) and two rotational (about x and y axes) degrees of freedom for each node of the FE model. Assuming there is no damping (C = 0) and no rotation (Ω = 0), the relevant eigenvalue problem is ...
A Multi-rotor System (MRS) is defined as a HAWT where two or more rotors are placed on a single turbine. From: Renewable and Sustainable Energy Reviews, 2022 About this pageAdd to MendeleySet alert Also in subject area: Materials ScienceDiscover other topics On this page Definition Chapters ...
All digits of the value stamp, date stamp and other stamps are adjusted automatically by means of alternate rotation in the two rotating directions (a, b). The motor receives its commands, via sliding contacts, from a control unit arranged outside the rotor cylinder. 展开 ...
The system state trajectory, Poincaré maps, power spectra, and bifurcation diagrams are used to analyze the dynamic behavior of the rotor and journal centers in the horizontal and vertical directions under different operating conditions. The analysis reveals a complex dynamic behavior comprising periodic...
Two rotors inside the casing without touching each other but dividing the cavity into several parts gives space for the fluid to fill in. As rotor moves in counter-clockwise directions, it carries the fluid from inlet to discharge port while generating pr...

Fig. 15.4 shows the rose plots of a less circular structure for the pile fabrics that were made from ring spun pile yarn, the surface exhibits the different FD in all the directions indicating anisotropy of surface texture or the presence of a dominant pattern in a certain direction. Fig. ...
The pneumatic rotor pump adopts two synchronously rotating rotors. The rotors are driven by a pair of synchronous gears in the box. The rotors are driven by the main and auxiliary shafts to rotate synchronously in opposite directions to change the volume of the pump, thus forming a high The ...
