WebProblem 4. An incompressible viscous liquid with density ρ fills the gap between two large, smooth parallel plates. The upper plate at x2 = h moves in the positive x1 -direction at speed U. The lower plate at x2 = 0 is stationary. An additive in the liquid causes its viscosity to vary in the x2 direction. WebThe fluid is modeled with the incompressible Navier-Stokes equations, and the structure is assumed linear elastic. The FSI model is discretized by an extended finite element method, and the fluid-structure coupling conditions are enforced weakly. The resulting nonlinear system of equations is solved monolithically with Newton's method. solargy inc
