S0502-1-1 DNSによる二次元乱流噴流の空間構造に関する研究([S0502-1]噴流,後流および剥離流れ現象の解明と制御(1))

Spatial structures of a turbulent plane jet are investigated by the direct numerical simulation (DNS) based on the finite difference method. Reynolds number is 1500. Special care has been paid to the boundary condition to reproduce proper entrainments. In this study, we focused on the pressure fluctuations, velocity gradient tensors, and rate-of-rotation tensors in the transition region of the jet, which are difficult to measure.
