About
Wilfried Coenen’s research sits at the intersection of fluid dynamics, acoustics, and micro-mechanics, with a particular focus on the behavior of thin films of air in confined geometries. His most-cited work, "Viscoacoustic squeeze-film force on a rigid disk undergoing small axial oscillations" (2021, 13 citations), tackles a classic problem in micro-electromechanical systems (MEMS) and proximity sensing: the air flow generated when a small disk vibrates near a parallel surface. Coenen’s contribution here is significant—he moves beyond the traditional Reynolds-equation-based simplifications that have long dominated the field, instead developing a rigorous viscoacoustic model that captures the full compressibility and viscous effects of the gas. This work provides a more accurate framework for predicting squeeze-film damping forces, which are critical for the design of high-frequency resonators, atomic force microscopes, and other precision devices. By bridging theoretical acoustics with practical engineering challenges, Coenen has established himself as a key figure in advancing the fundamental understanding of micro-scale fluid-structure interactions, offering tools that enable more reliable and efficient micro-device performance.
