A: Modeling of heart murmur generated by a constriction in an artery. (Left): Schematic of the set-up Turbulent flow in the stenosed tube embedded within a tissue mimicking viscoelastic cylinder (Middle): Turbulent flow in the stenosed tube. (Right): Elastic waves in the viscoelastic media resolved by the simulation. B: Comparisons between the simulation results and the experimental measurements. (Left): Frequency spectra of radial accelerations measured on the outer surface of gel material. Exp-BIOPAC: measurement by BIOPAC contact microphone, Exp-HP: measurement by HP accelerometer. (Right): Variation of spectral energy of the signal for three different frequency bands; solid line with filled symbol: simulation; dashed line with hollow symbol and error bar: experimental measurement.
