We study the development of perturbations in a submerged air jet with a round cross-section
and a long laminar region (five jet diameters) at a Reynolds number of 5400 by both inviscid …

We optimize jet mixing using large eddy simulations (LES) at a Reynolds number of
momentum flux of the main flow, which is one order of magnitude lower than an ad hoc dual …

The paper presents the results of numerical simulations of excited incompressible jets with
the transport of a passive scalar field. A forcing is obtained through an axial and helical …

A computational analysis of excited round jets is presented with emphasis on jet bifurcation
phenomenon due to superposition of axial and flapping forcing terms. Various excitation …

A new compact active turbulence generator is developed, tested, and characterized, which
extends the capabilities of such generators used in turbulent premixed combustion research …

This paper concentrates on the application of passive and active flow control methods to jet
flows. The passive control is obtained by shaping a nozzle cross-section (hexagonal …

A temporally evolving turbulent plane jet is studied both by direct numerical simulation
(DNS) and Lie symmetry analysis. The DNS is based on a high-order scheme to solve the …

A turbulent round jet with a Reynolds number of 8000 based on the minijet exit diameter is
experimentally manipulated using 1–6 unsteady radial minijets. Five control parameters are …

The paper presents a new insight into understanding a mechanism to trigger the Crow and
Champagne preferred mode. It is shown on the basis of numerical simulations that the …

Jet mixing of a circular nozzle in two different configurations is extensively investigated using
large-eddy simulation (LES), ie, the lip-ribbed one with an annular rib at the nozzle exit, and …
