Technique for Determination of Phase Changes in Moist Air Flowin a Blade Cascade
Vestfálová, M. ; Šafařík, P. ; Šimurda, David
The paper deals with theoretical and numerical tool for prediction of phase changes in moist air flow in flow systems. Partially solidified or liquidized steam in moist air appears to be a problem for peration wind tunnels, turbomachines, etc. Determination of phase change conditions is based on thermodynamic theory. Parameters of saturated homogeneous moist air are solved when expansion process is simulated at calculations. Conditions of saturation are successively verified and finally determined. Special phase diagram for moist air is designed.
BASIC CHARACTERISTICS OF ARRAY OF PULSATILE JET
Novotný, P. ; Vít, Tomáš ; Vestfálová, M.
The presented paper shows the results of measurement of basic characteristics of array of pulsatile jets which are used to enhance the efficiency of ejectors. Four pulsatile jets forms cross like structure where perpendicular couples are operating in two basic modes (a) in phase and (b) in antiphase. Paper presents phase averaged velocity profiles and velocity fields. All of the presented experiments are realized using hot wire anemometry method.
