Abstract:
This report contains results of investigation into hydrodynamics of artificial heart valves by means of photochromic flow visualization (PFV). The PFV method is based on activation of colored tracers in originally colorless photochromic solutions by pulse laser radiation during 10(-6)-10(-9) sec.
