Figure 4. Calculated curves of pressure amplitude versus frequency for RBCs and MFC7 cell nuclei at an outside point on the rotation axis (with z = 10.0 μm for RBCs and z = 20.0 μm for MFC7 cell nuclei) under various settings of the mass density ρf and acoustic speed vf of the surrounding medium.
(a,b) Results for RBCs. The black curve presents the result when ρf and vf are the same as those of RBCs (in Table 1). The green curve presents the result when ρf and vf are slightly smaller which are ρf = 1077 kg/m3, vf = 1602 m/s. The red curves presents the result of simulating the RBCs suspended in blood plasma where ρf = 1000 kg/m3, vf = 1520 m/s. (c,d) Results for MFC7 cell nuclei. The black curve presents the result when ρf and vf are the same as those of MFC7 cell nuclei (in Table 1). The green curve presents the result when ρf and vf are slightly smaller which are ρf = 1177 kg/m3, vf = 1536 m/s. The red curves presents the result of simulating the MFC7 cell nuclei surrounded by cell plasma where ρf = 1000 kg/m3, vf = 1527 m/s.
