RISFourier-Bessel Series Solutions for Radial Response of Anchorage Performance of FRP Tendon
Publisher: American Society of Civil Engineers
Abstract: According to the characteristic of periodic intended surface along longitudinal direction of Fiber Reinforced Polymer/Plastics (FRP) tendon, a reliable analytical method was developed for radial response of bond-type ...
A Comparison of Static and Rotordynamic Characteristics for Two Types of Liquid Annular Seals With Parallelly Grooved Stator/Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Liquid annular seals with parallelly grooved stator or rotor are used as replacements for smooth plain seals in centrifugal pumps to reduce leakage and break up contaminants within the working fluid. Parallelly grooved ...
Influence of Annular/Pocket Groove on the Static and Rotordynamic Characteristics of Hole-Pattern Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Annular damper seals, such as hole-pattern seals, are widely used to control leakage and enhance rotordynamic stability in turbomachinery, especially, for the balance-piston seal in the straight-through multistage centrifugal ...
Numerical Investigation on the Leakage and Rotordynamic Characteristics for a Hole-Pattern Seal in Wet-Gas Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: For turbomachinery working in wet-gas conditions, liquid-phase fluid may worsen the rotordynamic characteristic of an annular seal, which induces a subsynchronous vibration problem and destabilizes the rotor-bearing system. ...
Experimental Study on Behaviour of Concrete Box Girder Prestressed with External CFRP Tendons
Publisher: American Society of Civil Engineers
Abstract: A concrete thin-walled box girder prestressed with external CFRP tendons has been made, and tested in the course of CFRP tendons tensing until concrete cracking. Prestressing loss and some behaviors under uniform load such ...
Numerical Investigation on the Leakage and Rotordynamic Characteristics for Three Types of Annular Gas Seals in Wet Gas Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The modern compressor operation is challenged by the liquid presence in wet gas operating conditions. The liquid phase may affect the compressor stability by partially flooding the internal annular gas seals and inducing ...
Static and Rotordynamic Characteristics for Two Types of Novel Mixed Liquid Damper Seals With Hole-Pattern/Pocket-Textured Stator and Helically Grooved Rotor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Noncontacting liquid annular seals, such as helical groove seals, are widely used at the impeller interstage and shaft end in the liquid turbomachinery to reduce the fluid leakage and stabilize the rotor-bearing system. ...
Rotordynamic Characteristics of a Novel Labyrinth Seal With Swirl Brakes at Seal Entrance and Cavity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Annular gas seals used in turbomachinery are key elements to ensure a high machine efficiency, due to their effect on the leakage flow. As the most common type of annular gas seals, labyrinth seal is widely used as end and ...
