Abstract

Two compact models and one mixed-level model of squeeze-film damping in perforated microstructures are benchmarked w.r.t. pressure-dependent experimental data of three microstructures of different sizes and with different perforation levels. The mixed-level model shows very good agreement with the measured data. The maximum error at normal pressure is 4 %. The compact models show acceptable agreement for the largest structure, but show errors exceeding 30 % for the smaller structures. An analysis of pressure profiles indicates that the considerable error of the compact models originates from neglecting boundary effects. The mixed-level model includes boundary effects and is thus able to produce accurate results for all of the three structures.
