Analyze simultaneous flow of gas and liquid in pipelines
Enter the basic parameters for your two-phase flow system
Determine the flow regime and transition boundaries
Calculate two-phase pressure drop using various methods
Two-phase flow regimes describe the spatial distribution of gas and liquid phases in a pipe. Common regimes include:
The Lockhart-Martinelli method correlates two-phase pressure drop by defining a parameter Xtt:
The Homogeneous model treats the two-phase mixture as a single fluid with averaged properties:
Where φL is the two-phase multiplier based on Xtt.

Two-phase flow is encountered in numerous industrial processes including oil and gas production, power generation, refrigeration systems, and chemical processing. Understanding flow behavior is critical for equipment design and operational safety.
Two-phase flow analysis involves calculating several important parameters:
Baker, Taitel-Dukler, Hewitt-Roberts
Drift flux, Zivi, Chisholm correlations
Lockhart-Martinelli, Friedel correlations
