WebApr 12, 2024 · In contrast, the DPPC bilayer exhibited only a broad absorption peak at approximately 3.08 THz (Figure 1b). Although a characteristic absorption peak at approximately 3.0 THz was not observed for SPH, the SPH absorption coefficient no longer increased with a frequency exceeding 3.0 THz (Figure 1c). The broad character of its … WebComputing the forces acting from a surrounding air phase onto an SPH free-surface fluid is challenging. For full multiphase simulations the computational overhead is significant and stability issues due to the high density ratio may arise. In contrast, the air-fluid interactions can be approximated efficiently by employing a drag equation. WebJul 30, 2024 · "Density Contrast SPH Interfaces".
