Project

Flow control of boundary layer using DBD plasma actuators (GP14-25354P)

The proposed project is oriented to effect of plasma DBD actuator on a boundary layer. Cases of zero-pressure-gradient boundary layer on flat plate and on curved boundary layer flow will be studie...

Investigation of the receptivity of a laminat boundary layer to local intensity and length scale of outer stream disturbances (IAA2076602)

The prediction of by-passed transition of a laminar boundary layer is still this process. Not long ago, it has been proved that the boundary layer receptivity and the parameters of a transitional boundary ...

High-resolution model of planetary boundary layer for modelling of high concentration episodes of air-pollution in urban sites (GA205/01/1120)

Processes in the urban atmospheric boundary layer are extremely complicated. But these processes mainly affect a spatial distribution of instantaneous values of air-pollution concentrations in urban regions. The processes in the urb...
