RISOn Stability Analysis of a Flexible Cylinder in an Array of Rigid Cylinders
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The concept of an unsteady control volume is used to predict the onset of instability for a simple array of cylinders. The array consists of a flexible cylinder placed amidst rigid cylinders. ...
Predictions of Momentum Transfer Between Rotating Cylinders: The Narrow Gap Problem
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The contributions to momentum transfer by secondary motion, which arises beyond the marginal state of stability in a layer of fluid confined between rotating cylinders is calculated by an ...
A Two-Temperature Model for Turbulent Flow and Heat Transfer in a Porous Layer
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new model of turbulent flow and of two-temperature heat transfer in a highly porous medium is evaluated numerically for a layer of regular packed particles. The layer can have heat exchange ...
On Analysis of Fluidelastic Instability in Air-Water Mixture
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Cross-flow-induced vibrations are important phenomena in the power generation industry as they may severely damage the heat exchanger tubes due to violent oscillations and clashing. The fluidelastic ...
Low Pressure Differential Discharge Characteristics of Saturated Liquids Passing Through Orifices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental investigation has been performed to determine the effect of variation in the length-to-diameter ratios on the discharge characteristics of saturated liquids passing through square ...
Asymmetric Boundary Layer on a Nonisothermally Heated Cone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The development of a three-dimensional boundary layer along a heated cone is analyzed. The surface of the cone is heated under the condition of constant wall heat flux. The perturbation solution ...
Laminar Compressible Flow Between Rotating Disks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An integral method is used to obtain a solution for laminar flow of a compressible Newtonian fluid between rotating disks. The solution method is based on a Galerkin approach to the solution ...
Thermal Hydraulic and Two-Phase Phenomena in Reflooding of Nuclear Reactor Cores
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A quasi-steady, two-dimensional thermal hydraulic analysis of the two-phase region formed ahead of a quench front during reflooding of a slab or cylindrical core is carried out, and the results ...
The Hydrodynamic Stability of Rapidly Evaporating Liquids With Time Dependent Base States
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The hydrodynamic stability of a rapidly evaporating liquid surface is examined. The problem is modeled to mimic the case of a superheated liquid in equilibrium with its vapor in which, the ...
Experimental Rayleigh-Taylor Instability in a Circular Tube
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Rayleigh-Taylor instability of an air-water system has been investigated experimentally. The instability was produced by accelerating a slug of water down a vertical circular tube of 6.25 ...
