Instability Mechanisms and Stability Criteria of a Group of Circular Cylinders Subjected to Cross-Flow—Part 2: Numerical Results and Discussions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The fluid-force coefficients for a row of cylinders and a square array are determined from available experimental data and critical flow velocities are calculated as a function of system ...
Instability Mechanisms and Stability Criteria of a Group of Circular Cylinders Subjected to Cross-Flow. Part I: Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A mathematical model is presented for a group of circular cylinders subject to cross-flow. It is found that there are two basic dynamic instability mechanisms: instability controlled by fluid ...
Probabilistic Method to Compute the Optimal Slip Load for a Mistuned Bladed Disk Assembly With Friction Dampers
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, an analytical technique has been developed to compute the statistics of forced response of a mistuned bladed disk assembly with friction dampers (blade-to-blade or blade-to-ground). ...
A Review of Flow-Induced Vibration of Two Circular Cylinders in Crossflow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The flow field around a pair of rigid circular cylinders is very complex and has been studied extensively. When either one or both cylinders vibrate, the flow field becomes significantly more ...
Dynamics of Heat Exchanger Tube Banks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flow-induced vibration in heat exchanger tube banks is of great concern, particularly in high performance heat exchangers used in nuclear raactor systems. In this paper, the dynamic characteristics ...
Flow-Induced Vibrations in Two-Phase Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Two-phase flow exists in many shell-and-tube heat exchangers and power generation components. The flowing fluid is a source of energy that can induce small-amplitude subcritical oscillations and ...
Out-of-Plane Vibration and Stability of Curved Tubes Conveying Fluid
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A general theory is presented to account for the out-of-plane motion of uniformly curved tubes containing flowing fluid. The systems are grouped as conservative and nonconservative according to ...
Growth of the Boundary Layer on a Spherical Gas Bubble
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The unsteady flow of a pure viscous liquid past a gas bubble starting impulsively from rest is investigated theoretically. The Reynolds number is considered to be large so that boundary-layer ...
Finite Twisting and Bending of Thin Rectangular Orthotropic Elastic Plates
Publisher: The American Society of Mechanical Engineers (ASME)
Some Issues Concerning Fluid-Elastic Instability of a Group of Circular Cylinders in Cross-Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Since the early 1970s, extensive studies of fluid-elastic instability of circular cylinders in cross-flow have been reported. A significant understanding of the phenomena involved now exists. ...
