Investigation of the mechanism of particle transport and deposition in backward-facing step (BFS) flow is conducive to enhancing the understanding of the deposition characteristics of fly ash in the radiant syngas cooler (RSC). In this study, the reg

The backward-facing step flow (BFSF) is a classical problem in fluid mechanics, hydraulic engineering, and environmental hydraulics. The nature of this flow, consisting of separation and reattachment, makes it a problem worthy of investigation. In th

In this study, divided into two parts, the effect on a two-dimensional backward-facing step flow (BFSF) of a cylinder placed downstream of the step was numerically investigated. While in Part 1, the numerical simulations carried out without the cylin

In the present paper, the energy gradient method is implemented to study the instability of 2-D laminar backward-facing step (BFS) flow under different Reynolds numbers and expansion ratios. For this purpose, six different Reynolds numbers (50 ≤ Re

The effect of the expansion ratio on a backward-facing step flow is investigated experimentally. The expansion ratio ER ranges from 2.0 to 5.0. The Reynolds number based on the mean velocity and the hydraulic diameter of the inlet channel ranges from

This paper presents several test cases that were used to validate the implementation of two turbulence models in the UNS3D code, an in-house code. The two turbulence models used were the Shear Stress Transport model and the Spalart–Allmaras model.

This study investigates the flow control of backward-facing step flow by a dielectric barrier discharge (DBD) plasma actuator. The DBD plasma actuator is mounted onto the edge of the backward-facing step, and is driven by burst modulation. Velocity m
