Welcome to JAXA DNS Database site! This website is a portal to open representative turbulence statistics obtained from direct numerical simulations (DNSs) in wall-bounded turbulent flows.
Supersonic Channel Flow With Mixed Thermal Wall Conditions
Direct numerical simulation is used to investigate the turbulent Prandtl number (Prt) above cold (isothermal) and hot (adiabatic) walls in a family of supersonic channel flows. A range of Reynolds numbers and mean temperature/density variations is considered.
Turbulent channel flow
A series of direct numerical simulations (DNSs) have been performed in a turbulent channel flow with / without passive scalar transport over a range of Reynolds and Prandtl numbers.
Turbulent separation bubble
Direct numerical simulations (DNSs) have been carried out in a turbulent boundary layer (TBL) with separation and reattachment with focus on the effect of Reynolds number.
Skewed turbulent boundary layer
A series of direct numerical simulations (DNSs) have been performed in a non-equilibrium three-dimensional turbulent boundary layer (3DTBL) over a flat plate. Particular attention is given to the effects of cross flow and Reynolds number.
ZPG turbulent boundary layer
We have also performed DNSs of a zero-pressure-gradient (ZPG) turbulent boundary layer (TBL). The latter data are used as the inlet and comparison data for DNSs of a turbulent separation bubble and a skewed turbulent boundary layer.
