The influences of velocity on pressure losses in hydrate slurry

In recent years, hydraulic transfer in solid‐liquid flows has been paid considerable attention by many researchers. One of the most important parameters of this kind of flow is the pressure losses. This paper aims to focus on this aspect.

Two‐ and three‐layer models introduced by Doron are significantly capable of predicting the influences of slurry velocity on the pressure losses. In this research paper, using numerical methods, the related equations are solved for two‐ and three‐layer models and the influence of the slurry velocity on the pressure losses is studied.

The results show that, as long as there is a stable bed at the bottom of the pipe, the pressure losses are independent of the slurry velocity.

When the height of the stable bed becomes zero (when the stable bed disappears), the pressure losses increase considerably as the slurry velocity increases.
