His innovative approach has led to the development of a unified hydraulic model that addresses various flow regimes encountered in practical applications.

Latest Patents

Christian Pauchon holds a patent for a method that models multiphase flows in pipelines. This method is applicable to any slope and diameter of pipeline and can handle most steady-state as well as transient multiphase flow regimes. The new modelling technique differentiates between two types of flow patterns: separated flow patterns (stratified or annular) and dispersed flow patterns. Intermittent flow patterns, such as slug and churn flow, are combinations of these two patterns. The method ensures continuity of solutions across transitions between different flow regimes, which is crucial for simulating transient phenomena. The transient resolution is achieved through an explicit time-advancing scheme. The advantages of this method include its ability to follow wave front propagation and its ease of implementation for complex pipeline networks. The performance of the unified hydraulic model has been validated using extensive experimental data.
