Research AreasManufacturing of microsystems such as lab-on-chip analytical sensors, flow control, and micropropulsion devices will take a giant leap forward if cost-effective predictive modeling is available in areas where experimental diagnostic is limited or impossible. Gas flows in microsystems are characterized by low Reynolds and large Knudsen numbers, and large surface-to-volume ratios. This leads to flow phenomena in microsystems that are drastically different from their macroscale counterparts. For example, thermal stresses generated by temperature gradients in devices manufactured from now-available low thermal conductivity materials, such as aerogels, can be exploited to built gas pumps and actuators. The work in this area is aimed at the development of methods and tools for deterministic solution of the Boltzmann equation, which governs microscale gas flows; coupling of fluid flow and thermal/structural material response and quantification of uncertainties of the simulations.
