Turbulence structure and turbulence kinetic energy transport in multiscale/fractal-generated turbulence
TL;DR: In this article, the turbulence structure and turbulence kinetic energy transport in multiscale/fractal-generated turbulence in a wind tunnel are investigated, where a low-blockage, space-filling square-type fractal grid is placed at the inlet of the test section.
Journal ArticleDOI
Relevance of turbulence behind the single square grid to turbulence generated by regular- and multiscale-grids
Yi Zhou,Kouji Nagata,Yasuhiko Sakai,Hiroki Suzuki,Yasumasa Ito,Osamu Terashima,Toshiyuki Hayase +6 more
TL;DR: In this article, direct numerical simulations were carried out to study the turbulence generated by a fractal square grid at a Reynolds number of ReL0 = 20000 (based on the inlet velocity Uin and length of the largest grid bar L0).
Journal ArticleDOI
Direct numerical simulation of turbulent mixing in grid-generated turbulence
TL;DR: In this article, a turbulence-generating grid, on which the velocity components are set to zero, is located downstream of the channel entrance, and it is numerically constructed on the staggered mesh arrangement using the immersed boundary method.
Journal ArticleDOI
High-Schmidt-number scalar transfer in regular and fractal grid turbulence
TL;DR: In this paper, the mixing of high-Schmidt-number passive scalars in regular and fractal grid turbulence is experimentally investigated using a water channel, where a turbulence-generating grid is installed at the entrance of the test section, which is 1.5 m in length and 0.1 m×0.1m in cross section.
Journal ArticleDOI
Direct numerical simulation of fractal-generated turbulence
TL;DR: In this paper, the authors simulate fractal-generated turbulence by means of a direct numerical simulation and address its fundamental characteristics, and examine whether the fractal generated turbulence in the upstream region has a nature similar to that of a wake.
