RISEffect of the Honeycomb Tip With Injection on the Aerodynamic Performance in a 1.5-Stage Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Three kinds of rotor tip configurations have been investigated numerically in the LISA 1.5-stage turbine, including the flat tip, the honeycomb tip, and the honeycomb tip with injection. The effect of the cavity depth and ...
Effect of Pressure-Equalizing Film on Hydrodynamic Characteristics and Trajectory Stability of an Underwater Vehicle With Injection Through One or Two Rows of Venting Holes
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure-equalizing film is a slice of air film generated through exhausting and attached to the vehicle's exterior with nearly uniform inner pressure. Similar to ventilated cavity in composition, but of interest, here is ...
Flow Mechanism and Characteristics of Pressure-Equalizing Film Along the Surface of a Moving Underwater Vehicle
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pressure-equalizing film is a slice of air layer attached to vehicle exterior with nearly uniform inside pressure, similar to ventilated cavity in composition; it is generated through exhaust process of the inside air ...
Large Eddy Simulation of the Elliptic Jets in Film Cooling Controlled by Dielectric Barrier Discharge Plasma Actuators With an Improved Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The dielectric barrier discharge (DBD) plasma actuator, in which electrodes are asymmetric arranged, has already demonstrated its ability in flow control. In the present work, the configuration of DBD plasma actuator defined ...
Effective Control of Composite Honeycomb Structures on the Tip Leakage Flow in Turbine Cascade
Publisher: American Society of Civil Engineers
Abstract: Two innovative composite tip structures that combine a honeycomb with a prismoid or spherical bottom have been proposed to actively control the tip leakage flow in a turbine cascade. The mechanisms of inhibiting leakage ...
Effects of Uncertainties in the Launch Parameters on the Pressure-Equalizing Air Film Around a Vertically Launched Underwater Vehicle
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Many uncertain factors in the water-emerging process of a vehicle influence the taking effect of the air film around its shoulder in the load reduction and attitude control. Assuming the launch parameters (launch depth, ...
