On the Lubrication and Stability Behaviors of a Conical Hybrid Floating Ring Bearing With Thermal Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The conical bearing can withstand both journal and axial load because of the conical-shape fluid film, and an investigation concerning the thermodynamic lubrication and stability properties is proposed for a conical ...
Effect of Trailing Edge Modification of a Mixed Flow Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern pumps are designed to guarantee a sufficiently large operating range or to satisfy the performance requirements relative to more than one operating point. This study applies trailingedge (TE) modification method ...
Three Dimensional Coupling Analysis of Flow and Thermal Performance of a Mechanical Seal
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To accurately obtain the flow and temperature field in mechanical seals and investigate the key influencing factors, a numerical analysis of flow and heat transfer in a contact mechanical seal with highsealing pressure, ...
Transient Characteristics of a Closed Loop Pipe System During Pump Stopping Periods
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to study the transient characteristics of a closedloop pipe system with room temperature water, experiments were carried out based on different pump stopping periods from rate rotational speed to zero. Various ...
Design, Modeling and Testing of a Two Terminal Mass Device With a Variable Inertia Flywheel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we present a flywheel that can adaptively generate variable equivalent mass in response to application requirements. The motivation for the design comes from the need to achieve passive inertial mass, which ...
A Novel Evaluation Index and Optimization Method for Ankle Rehabilitation Robots Based on Ankle-Foot Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The ability of ankle rehabilitation robots to accurately mimicking the actual human ankle motion is an important judgment basis for robot-assisted rehabilitation training. This paper proposes an evaluation index and mechanism ...
Improve of Unsteady Pressure Pulsation Based on Jet–Wake Suppression for a Low Specific Centrifugal Pump
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, three impellers with different blade pressure side (PS) profiles are designed and the influence on the hydraulic and dynamic performance of a low specific speed centrifugal pump is investigated by numerical ...
Computational Fluid Dynamics-Based Pump Redesign to Improve Efficiency and Decrease Unsteady Radial Forces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study, a double volute centrifugal pump with relative low efficiency and high vibration is redesigned to improve the efficiency and reduce the unsteady radial forces with the aid of unsteady computational fluid ...
Numerical Simulation of a Check Valve Closure Induced by Pump Shutdown
Publisher: American Society of Civil Engineers
Abstract: High pressure surges induced by the sudden closure of check valves can cause severe damage to mechanical and hydraulic facilities. A three-dimensional unsteady numerical simulation of a dual disc check valve closure induced ...
Numerical Analysis of Temperature Fields and Thermal Stress Fields in Heating Process of Large-Diameter Seamless Steel Pipe Blanks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the piercing process of large-diameter seamless steel pipe blanks after heating, severe lateral cracks easily occur on the surface of pierced pipe blanks owing to the effects of the large temperature difference and ...
