Purpose Fluid flows in pipes whose cross-sectional area are increasing in the stream-wise
direction are prone to separation of the recirculation region. This paper aims to investigate …

The complex flow resulting from the laminar-turbulent transition in a sudden expansion pipe
flow, with expansion ratio of 1: 2, subjected to an inlet parabolic velocity profile and a vortex …

In the present study, the unsteady flow through a sudden expansion pipe with an expansion
ratio of 1: 3 is numerically modeled using dynamic delayed detached-eddy simulation …

A robust microreactor with a sudden expansion structure was employed to facilitate
controllable mixing with a mixing time ranging from 5.3 to 225.8 ms for water-acetonitrile …

This study aims at investigating the inlet flow conditions of flow through an axisymmetric
sudden expansion with an expansion ratio of 2.0. A series of large eddy simulations with the …

Numerical simulation of isothermal multi-component gas flow was conducted to study fluid
