On Parameters of Shock Waves in Saturated Steam
Nový, A. ; Jícha, D. ; Šafařík, Pavel ; Hajšman, M.
The paper deals with theoretical and numerical study of shock wave parameters in saturated steam. Theoretical approach is based on mass, momentum and energy balance equations. An iterative procedure for solution of state parameters is derived. Numerical solution of steam parameters is performed by means of the iterative procedure using the IAPWS-IF97 water and steam thermodynamic properties. Results are presented and compared with results obtained from ideal gas theory.

Measurements of 3D Flow Field Behind the Blade Cascade SE 1050
Šimurda, David ; Luxa, Martin
The paper is concerned with measurements of 3D flow field at exit of the Blade Cascade SE1050. Data was collected using traversing device with a small five-hole conical probe. Prior to measurements of the flow exiting the blade cascade, investigations of inlet velocity profile and inlet turbulence intensity were conducted. Measurements of exit flow field were performed at design angle of incidence and at a transonic and a subsonic regime. Data analysis reveals development of distinctive vortex structures resulting from non-uniform inlet velocity profile. Origin of these structures results in increased loss of kinetic energy and spanwise shift of kinetic energy loss coefficient distribution.
