Two-Phase Flow-Induced Vibration: An Overview (Survey Paper)
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase flow exists in many industrial components. To avoid costly vibration problems, sound technology in the area of two-phase flow-induced vibration is required. This paper is an overview ...
Dynamics of Flexible Cylinders in Axisymmetrically Confined Axial Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes experiments in which flexible cylinders placed centrally within a narrow cylindrical flow channel were subjected to axial flow. The dynamical behavior of such cylinders, ...
Effect of Flow Regime and Void Fraction on Tube Bundle Vibration
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase cross flow occurs in industrial heat exchangers such as condensers, boilers, and steam generators. Under certain flow regimes and fluid velocities, the fluid forces result in tube ...
Vibration of a Normal Triangular Tube Bundle Subjected to Two-Phase Freon Cross Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the results of a test series to study the vibration behavior of a normal triangular tube bundle subjected to two-phase Freon cross flow. A normal triangular tube bundle ...
Random Excitation Forces in Heat Exchanger Tube Bundles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Random excitation forces can cause low-amplitude tube motion that will result in long-term fretting-wear or fatigue. To prevent these tube failures in heat exchangers, designers and troubleshooters ...
Vibration Excitation Forces Due to Two-Phase Flow in Piping Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Severe vibrations were observed in a small piping system comprising two elbows and straight sections configured in the form of a U and subjected to air-water internal two-phase flow. An ...
Fluidelastic Instability of Heat Exchanger Tube Bundles: Review and Design Recommendations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fluidelastic instability is the most important vibration excitation mechanism for heat exchanger tube bundles subjected to cross-flow. Most of the available data on this topic have been reviewed ...
Damping of Heat Exchanger Tubes in Two-Phase Flow: Review and Design Guidelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase flow exists in many shell-and-tube heat exchangers such as condensers, evaporators, and nuclear steam generators. Some knowledge on tube damping mechanisms is required to avoid flow-induced ...
Vibration of Tube Bundles Subjected to Two-Phase Cross-Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase cross-flow exists in many shell-and-tube heat exchangers such as condensers, reboilers and nuclear steam generators. Thus we are conducting a comprehensive program to study tube bundle ...
Fluidelastic Instability of an Array of Tubes Preferentially Flexible in the Flow Direction Subjected to Two-Phase Cross Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Almost all the available data about fluidelastic instability of heat exchanger tube bundles concerns tubes that are axisymmetrically flexible. In those cases, the instability is found to be ...
