One technique to measure mass flow in a microchannel is to measure the pressure drop over a well controlled orifice. Because of the small dimensions, the measurements are difficult to make precise. Manufacturing of MEMS components are expensive and time consumptive, it is therefore desirable with a computational model which can provide approximative, but yet qualitative, input on how to design the components. I will discuss the problem of making a computational model of an orifice microchannel, perform computations using a high-order Navier-Stokes solver and verify the results with experimental data.
