tur′bulent flow′

the flow of a fluid past an object such that the velocity at any fixed point in the fluid varies irregularly.

[1920–25]

tur·bu·lent flow

(tûr′byə-lənt)

Movement of a fluid in which the individual particles of fluid move in irregular patterns even though the overall flow is in one direction. Turbulent flow is common in nonviscous fluids moving at high velocities. Compare laminar flow.

The turbulent flow in an axial flow impeller was numerically simulated in the clear water (single-phase flow) and the sandy water (solid-liquid two-phase flow) conditions.

Sapsis and coauthor Mohammad Farazmand created an algorithm that blends dynamical equations with weather data to determine what conditions act as precursors to turbulent flow. Predicting severe events in complex systems normally involves solving dynamical equations that are developed based on a system's underlying physics, which often are poorly understood and contain key model errors, causing the equations to be unreliable.
