Title: Unsteady Wall Laws and Applications

Objective: To extend the wall laws to unsteady laminar flows based on domain decomposition methods and on asymptotic development methods. The unsteady wall laws are applied to treat rough boundaries and synthetic jets. As an application we will investigate fluid-sctruture iteration problems.
