Characteristics of Snow and/or Ice/Water Mixture Flowing in Pipeline.

Blocking of Snow/Water Slurry Flow in Pipeline Caused by Compression-Strengthening of Snow Column

In earlier works by the present authors, two systems for sustainable energy were proposed: (i) a system for urban snow removal in winter and storage for air conditioning in summer, applied to Nagaoka City, which suffers heavy snow fall every winter, and (ii) a district cooling system utilizing latent heat of ice to reduce the size of storage reservoir and transportation pipeline system. In thes...

The Indication of Two-Phase Flow Pattern and Slug Characteristics in a Pipeline Using CFD Method

Multiphase flows are commonly encountered in oil and gas industries. The transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the Baker chart. The effects of small downward inclinations of ...

Simulation of Mixture Flows : Pollution Spreading and Powder–Snow Avalanches

We are concerned with the numerical simulation of certain multi-fluids flows, which in particular arise in the modeling of pollutant spreading and powder–snow avalanches. The behavior of the mixture is described through a single mass density and a velocity field, with an unusual constraint that relates the divergence of the velocity to derivatives of the density. We propose a numerical scheme b...

Threshold scaling limits of RO concentrates flowing in a long waste disposal pipeline.

Disposal of RO concentrates emanating from inland brackish water desalination plants presents a difficult environmental problem. The solution adopted by Mekorot--the National Water Company of Israel--is to construct a 30 km waste disposal pipeline for collecting concentrates emanating from several RO desalination plants and discharging them into the sea. The discharged concentrates are highly s...
