Chezy and Manning developed equations that are used to determine the average volumetric flowrate in open channels. This article explains a laboratory method that was developed and tested to further ...

The Richards equation remains a cornerstone in the modelling of water transport within unsaturated porous media, integrating both Darcy’s law and mass conservation to describe complex water dynamics.

A novel approach using computational fluid dynamics techniques provides a way for determining the characteristics of gas passing through a gas-lift valve. In the method, CFD calculations numerically ...

A new empirical correlation can help engineers size chokes for controlling gas-condensate production and predicting the performance of flowing wells under different conditions. The correlation was ...

Models of glacial flow and retreat rely on estimates of glacial ice viscosity, the measure of the ice's resistance to flow.
