Xcompact3D is a Fortran 90–95 open-source framework designed for fast and accurate
simulations of turbulent flows, targeting CPU-based supercomputers. It is an evolution of the …

An experimental investigation involving space-filling fractal square grids is presented. The
flow is documented using particle image velocimetry (PIV) in a water tunnel as opposed to …

We perform particle image velocimetry (PIV) measurements of various terms of the non-
homogeneous Kármán–Howarth–Monin equation in the most inhomogeneous and …

A new passive method for the heat transfer enhancement of circular impinging jets is
proposed and tested. The method is based on enhancing the mainstream turbulence of …

Past results have suggested that the drag coefficient and the shedding frequencies of
regular polygon plates all fall within a very narrow band of values. In this study, we introduce …

R e L 0= 20000 (based on the inlet velocity U in and length of the largest grid bar L 0). We
found that in the near-field region, the fractal square grid can generate much higher …

We simulate fractal-generated turbulence (Hurst and Vassilicos 2007 Phys. Fluids 19
035103)) by means of a direct numerical simulation and address its fundamental …

The flow on the centerline of grid-generated turbulence is characterized via hot-wire
anemometry for three grids with different geometry: a regular grid (RG60), a fractal grid …

The opposed jet configuration presents an attractive canonical geometry for the evaluation
of burning properties of turbulent flames with past studies typically limited to low Reynolds …

The use of fractal grids in a low-swirl burner can significantly increase the turbulent
combustion rate, realizing a higher power density in these flames. The standard turbulence …
