Application of Thermodynamic Stability Condition to the Turbulence Modelling
The paper deals with two approaches of the turbulence modelling using the termodynamic stbility condition. The first is based on exact average of density disipated energy. The second utilizes the Bousinesque hypothesis for tensor of...

Preliminary results of the conditional analysis of wall friction during laminar-turbulent transition of a rough wall boundary layer
The conditional analysis of the instantaneous wall friction is applied on time records made in transitional boundary layers originating on smooth surface or surface covered by sand paper (grits 60) under turbulent free stream. The a...
