In vivo examination of the aorta using a hot-film anemometer system suggested that the extent of flow disturbances may be influenced by both peak flow velocity and pulse-rate.
In vivo measurement using a hot-film anemometer demonstrates that aortic flow disturbances are influenced by peak flow velocity and pulse rate.
The general nature of flow-disturbances and turbulence in fluid flows, and the special features which may govern their appearance in unsteady flows, are considered. A hot-film anemometer system, modified for use within arteries, has been used to examine flow disturbances in the aorta. Results suggested that the extent of flow-disturbances may be influenced by both peak flow velocity and pulse-rate, expressed in terms of the relevant fluid dynamic parameters. Possible underlying mechanisms are discussed, and power spectra for laminar and highly disturbed aortic velocity waveforms presented.
Nerem et al. (1972) studied Aortic flow disturbances. Peak flow velocity and pulse-rate was evaluated on Extent of flow-disturbances. In vivo examination of the aorta using a hot-film anemometer system suggested that the extent of flow disturbances may be influenced by both peak flow velocity and pulse-rate.
