RISAffinity Law Modified to Predict the Pump Head Performance for Different Viscosities Using the Morrison Number
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The goal of this study is to provide pump users a simple means to predict a pump's performance change due to changing fluid viscosity. During the initial investigation, it has been demonstrated that pump performance can ...
Computational Fluid Dynamics and Particle Image Velocimetry Characterization of a Solar Cyclone Reactor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solar thermal cracking of methane produces two valuable products, hydrogen gas and solid carbon, both of which can be used as a fuel and as a commodity. During the course of this twophase phenomenon, carbon particles tend ...
An Inquiry of the Friction Factor “Jump†Phenomenon in Hole Pattern Seals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments measuring the leakage rate through holepattern seals operating at high pressures of up to 8400 kPa reveal the presence of an abrupt variation in the friction factor (up to a factor of three) with change in ...
Computational Fluid Dynamics and Heat Transfer Analysis of Vortex Formation in a Solar Reactor
Publisher: The American Society of Mechanical Engineers (ASME)
