Simulations Unit
The Computer Simulations Unit offers consulting, expert assessments, and numerical modeling services for the analysis and development of complex physical systems. Our expertise covers computational fluid dynamics, acoustofluidics, microfluidics, ultrasound-driven processes, microhydrodynamics, and the dynamics of colloidal and microparticles.
We support research and development projects from model formulation and the selection of suitable numerical methods through simulation and analysis to the optimization of processes, devices, and operating conditions. For fluid-mechanical problems, we apply numerical methods such as the finite-volume method to investigate low-Reynolds-number flows, microfluidic chips, acoustic streaming, and ultrasound-induced flow phenomena. We also model acoustic radiation forces and the transport and dynamics of microparticles in microfluidic and acoustofluidic systems.
A further focus is the development and application of theoretical and field-theoretical models. This includes the derivation, implementation, and application of field-theoretical and phase-field models, as well as consulting on the selection and use of suitable modeling approaches for specific scientific questions. For colloidal particles and microparticles, we calculate quantities such as hydrodynamic resistance matrices, Stokes drag, and diffusion coefficients to describe particle motion and transport at the microscale.
By combining numerical simulation, theoretical modeling, and application-specific consulting, we support the development and optimization of microfluidic, acoustofluidic, and particle-based systems and provide quantitative insight into processes that are difficult to access experimentally.
