Modelování interakce kardiovaskulárního a respiračního systému
Převorovská, Světlana ; Maršík, František
The real cardiovascular and respiratory system in the model developed in the IT CAS is approximated by four segments of pulsating heart and twenty two vascular segments of pulmonary and systemic circuits including the coronary and bronchial circuits. Respiratory processes are considered at the level of pulmonary, tissue and brain segments. The interaction between the both systems is modelled by baroreflex and chemoreflex control loop.

Syntetizovaný proud - návrh generátoru a ověření jeho funkce
Trávníček, Zdeněk ; Vít, T. ; de Boer, P. ; Maršík, František
A zero-net-mass-flux actuator was designed, and a synthesis of an air jet was investigated. The operating parameters were suggested near the resonance frequency. The proper actuation was experimentally tested by smoke visualization and hot-wire anemometry. Two typical synthetic jets are presented, namely the so-called "long" and "short" extruded fluid column cases. The maxima of the centerline local and the time-mean velocities reached approximately 27 m/s and 8.7 m/s, respectively.
