Välkomna till Magin som försvann, en blogg som handlar om Disneys live-action remakes, dvs fotorealistiska nyinspelningar av deras tecknade klassiker. Syftet med denna blogg är att lyfta den debatt som finns kring filmerna och själva bidra till d

The mechanisms leading to blowoff were investigated numerically by analyzing bluff body stabilized flame at two conditions: a condition far from blowoff to a condition just prior to blowoff. Large ...

A novel method is proposed to identify flow structures responsible for sound generation in confined flow past an inhibitor. Velocity fields obtained using Large Eddy Simulations (LES) are post-proc ...

The dynamics of a confined thick orifice plate jet, at Mach 0.4, are studied with dynamic mode decomposition (DMD), of the velocity from a large eddy simulation (LES). The jet exhibits strong periodic structures, due to an initially laminar shear lay

In this paper, the effect of a numerical model for plasma actuators, in the form of single dielectric barrier discharge, is evaluated. One such plasma actuator is modeled by a steady body force dis ...

International audience; Five different low-Mach large eddy simulations are compared to the turbulent stratified flame experiments conducted at the Technical University of Darmstadt (TUD). The simulations were contributed by TUD, the Institute for Com

The aim of thiswork is to study sound generating flowstructures in a thick circular orifice plate jet, placed in a circular duct. Large eddy simulations (LES) are performed for two jet Mach numbers, 0.4 and 0.9. Characteristic frequencies in the flow

Turbulent flow through 90° pipe bends, for four different curvatures, has been investigated using large eddy simulations. In particular, the origin of the so-called swirl switching phenomenon, which is a large scale oscillation of the flow after the
