RISInvestigation on Effect of Surface Roughness Pattern to Drag Force Reduction Using Rotary Rheometer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A drag force reduction experiment is performed on polyoxyethylene (PEO) water solution using a rotary rheometer. Longitudinal, transverse, and isotropic grooves are notched on the rotor’s surface ...
Experimental Investigation on Fiber Thermocouples Used in Brush Seals for Temperature Measurements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A type of fiber thermocouple is applied to a brush seal in order to obtain the temperature of the bristlerotor friction zone. Using a brush seal test rig, the temperature measurements utilizing a fiber thermocouple, infrared ...
Theoretical and Experimental Investigation on Tip Forces and Temperature Distributions of the Brush Seal Coupled Aerodynamic Force
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on a type of threedimensional slice model of a brush seal combined with the commercial CFD software FLUENT, the study calculated the leakage flow of the brush seal. The aerodynamic forces applied on upstream and ...
Dynamic Leakage Analysis of Noncontacting Finger Seals Based on Dynamic Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Noncontacting finger seals are new compliant seal in gas turbine engine sealing technology. Their potential hydrodynamic and hydrostatic lifting capabilities make them preferable to brush seals and contacting finger seals. ...
