Identifying governing equations from observational data is crucial for understanding nonlinear physical systems but remains challenging due to the risk of overfitting. Here we introduce the Bi-Level ...

Numerical analyses and surrogate models based on the compressible Euler and Navier–Stokes equations are essential for understanding and estimating nonlinear physical phenomena in fluid dynamics.

A relatively simple method of estimating sand velocity and hold-up in multiphase flowlines allows a design engineer to determine whether a producing well needs a sand-exclusion system at a subsea ...
