A diffuser for a gas turbine contains diffuser walls could possibly occur, which define the compressor outlet air diffuser ducts. The diffuser walls could possibly occur diverge in a direction of flow. A a flow control device is arranged in the diffuser ducts can and contains a plasma control,...
Additionally flow is vectored by the use of vanes, a basic passive type of flow control. An experimental investigation was performed to study the application of flow control on that of a HVAC diffuser using synthetic jets distributed evenly along the diffuser edge parallel to the flow field. ...
This experimental study investigates the control of flow in a short diffuser with a 2 × 45° divergence angle, using wall synthetic jets. Measurements are made by particle image velocimetry. Velocity profiles, velocity fields, and vorticity maps show that the flow, initially separated as a free...
Analysis of pressure losses in the diffuser of a control valve The pressure loss in the diffuser of a control valve is evaluated by using CFD computations. Pressure ratios and lifts of a cone for the recommended flow characteristics of an experimental turbine are considered. The pressure loss in...
A crossflow cooling tower, water flow control valve and diffuser which includes an open ended inner valve cylinder which moves from a closed to an open position by means of a screw mechanism and allows water to be evenly distributed over a 360 DEG range to all parts of a hot water basin ...
In an axial-flow compressor, the device for bleeding off secondary air, employing a revolving offtake slot which is designed, at least in part, as a diagonal diffuser, is characterised in that means are arranged, in or directly at the of... ...
Grooves have been proposed perpendicular to the flow direction in different planes along the aggressive diffuser. The simulated flow field was generated within a normal S-shaped diffuser with curvature of 45°/45°, and then simulated for aggressive diffuser with 30730° by reducing the total ...
Flow control using zero-net-mass-flow jets in a twodimensional model of an S-Shaped air intake diffuser was investigated. Experiments were conducted in a channel flow facility at a Reynolds number of Re = 8×104 with particular image velocimetry measurements in the symmetry plane of the duct....
The passive control was achieved by installing a porous wall around the throat and a cavity underneath so that the flow in the diffuser can circulate through the porous wall and the cavity. The result shows that the passive control reduced the root-mean-square intensities of the wall static ...
The subsonic separation zone generated by the shock train will affect the inlet flow field when the shock train is pushed out of the diffuser which results in inlet unstart and affects the operation of the engine. In order to take the advantages of shock train to reach a maximum pressure ...
