Air-Water Drainage Flow through Finned Bend

Effects of Non-Uniform Refrigerant and Air Flow Distributions on Finned- Tube Evaporator Performance

An experimental investigation was implemented to determine the capacity degradation due to non-uniform refrigerant and air flow distributions, and to assess the potential to recover the lost capacity via controlling refrigerant distribution between individual refrigerant circuits. The tests were performed on a three-circuit, threedepth-row, finned-tube evaporator. Refrigerant inlet quality, exi...

Air Flow through Woven Stainless Steel Mesh

It was known that a mesh screen placed across an airflow will have an evening effect, distributing both the velocity and pressure across the screen, however this effect had not been quantified and the effect of different mesh geometries was unknown. It was desired to understand the relationship between airflow velocity, the pressure behind the screen and the free hole area of the screen. It was...

Acid Mine Drainage: Flow-Through Experiments Examining Pyrite Dissolution Rates

Two-Phase (Air and Water) Flow through Rock Joints: Analytical and Experimental Study

This research study deals with the characterization of two-phase flow in a fractured rock mass. A comprehensive mathematical model with which to predict the quantity of each flow component in a single joint is developed. A joint with two parallel walls filled with layers of water and air stratified is analyzed. The effects of mechanical deformation of the joint, the compressibility of fluids, t...

Flow of Single-Phase Water and Two-Phase Air-Water Mixtures through Sudden Contractions in Mini Channels

Pressure drop through sudden contraction in small circular pipes have been numerically investigated, using air and water as the working fluids at room temperature and near atmospheric pressure. Two-phase computational fluid dynamics (CFD) calculations, using Eulerian– Eulerian model with the air phase being compressible, are employed to calculate the pressure drop across sudden contraction. The...
