Reduced order modeling of transient two-phase flows and its application to upward two-phase flows in the under-balanced drilling

作者：

Highlights：

• Reduced order modeling of two-phase flows is performed using POD.

• Equation-free/Galerkin-free POD assisted method is used for ROM.

• ROM of transient two-phase flow in under balanced drilling is performed using equation-free-POD.

• The POD can reduce computational time of two-phase flows.
