The Lattice Boltzmann Method (LBM) with a forcing scheme is used to simulate homogeneous isotropic turbulence, and the resolutions of 1283 and 2563 are compared. Two models, D3Q15 and D3Q19, are used in the investigation. Results demonstrate that the

The structure at a spanwise edge of spreading turbulent region is studied in a wind tunnel experiment using conditional-sampling and ensemble-averaging techniques. A turbulent region is created by locally tripping the laminar boundary layer using two

A semi-automatic and active control of T-S waves and oblique waves in a transitional flat plate boundary layer is carried out in a wind-tunnel experiment and a numerical simulation. An array of piezo-ceramic actuators attached on a surface is used to

A passive control of aerodynamic noise generated by a laminar separating flow over a cavity is carried out in a wind tunnel test and by numerical simulation, using a thin plate inserted into the cavity as a passive flow-controlling device. In the exp

An attempt to extract multi-scaled vortical structures from a turbulent field is carried out. The Lattice Boltzmann method with forcing is used to generate a statistically stationary velocity field in a resolution of 2563. Two methods for filtering,

A semi-automatic and active control of T-S waves and oblique waves is performed using an array of piezo-ceramic actuators attached on a flat-plate surface. The actuators generate counter waves to cancel the incoming instability waves. The actuator’

The aim of this study is to develop a method to control two-dimensional Tollmien-Schlichting wave (T-S wave) and oblique wave at the early stage of transition of a flat-plate boundary layer. Small and thin piezo-ceramic (PZT) actuators are used as th
