Bykov Y. Numerical modeling of three-dimensional viscous gas flow through vibrating blade rows of turbomachines

The object is turbomachine blade row in unsteady viscous gas flow; the aim is to create a numerical model of unsteady aeroelastic behavior of the turbomachine blade row in spatial viscous gas flow; methods are the mathematical and numerical modeling; the new approach is the mathematical model and numerical calculation method of unsteady turbulent flow of viscous gas through the vibrating blade row with use of moving numerical grids, a study of originating mechanism of the three-dimensional stall flutter by means of the flow modeling in the turbomachine blade row; the main include is the software package for calculation of the aeroelastic characteristics of the turbomachine blade row, in design and off-design operating modes; this thesis has been applied in investigations of static and dynamic loads of turbomachine blade rows in design and off-design operating modes; the field is the turbomachine construction.
