While some engineers use computers as a first line of attack on design problems, others are persistently making computers and their software faster and more capable of solving realistic problems. The technology used to build the microscale electronic components that makes computers fast is also used to construct micron-scale electromechanical (MEMS) actuators ideal for use in control schemes to reduce drag in industrial flows, promising millions of dollars in cost savings. The Immersed Boundary Condition (IBC) developed here augments a common fractional step, pseudospectral method used with Large Eddy Simulation to inexpensively and more realistically simulate turbulent flow over MEMS-like actuators. This is done by augmenting the numerical method to simulate flow over unsteady, irregular boundaries with static, structured rectilinear grids. The method is validated and applied to evaluate actuator characteristics and simulate open and closed loop flow control with continuous and discrete, MEMS-like actuators.
