A Numerical Model of Blood Flow Velocity Measurement Based on Finger Ring

Figure 9

Empirical curves of the blood flow velocities and received temperatures in 5 situations, where the radius of blood vessel is set as 0.3 mm. “1”: one blood vessel is built in the model; “2s”: two blood vessels with the same direction of blood flow are built in the model; “2r”: two blood vessels with the reverse direction of blood flow are built in the model; “4s”: four blood vessels with the same direction of blood flow are built in the model; and “4r”: four blood vessels are built in the model where the blood flow directions of two blood vessels are the same while the blood flow directions of other two blood vessels are reverse.
