| 英文摘要 | Boundary slip phenomena on a superhydrophobic surface at a mesoscopic scale are investigated. Using the lattice Boltzmann method with a slip boundary, this paper simulates Couette flow at a mesoscopic scale and calculates the boundary slip length on superhydrophobic surfaces at various temperatures. The agreement of experimental and numerical results suggests the effectiveness of the current method for boundary slip problems. Furthermore, the results showed that slip length on a superhydrophobic surface boundary is above 100 µm at mesoscopic scale, and the surface friction is a lot less than with a non-slip boundary. The relationship between slip length and viscosity, contact angle, and velocity gradients in Couette flow is also examined. Numerical results show that the main factors affecting slip length are viscosity and contact angle. Velocity gradient has little effect on slip length. |
