Electric Ant Lab is an independent private research laboratory providing contract-research consulting and simulation services in the field of rheology and transport of complex fluids. Complex fluids are everywhere, examples range from blood and paint to smart materials such as liquid body armor and magneto-rheological fluids. In many cases their behaviour is not fully understood and there is large potential for improvements and new applications.
Deep Insight and Virtual Prototyping
High-fidelity simulation models and virtual experiments in the form of high-performance computer simulations are extremely powerful tools to understand, predict, and improve the rheology and transport of complex fluids and their processing. EAL works at the forefront of this technology, pushing its boundaries, and translates it to solutions in scientific and industrial contexts.
Micro-Dynamics of Complex Fluids
High-fidelity simulations provide quantitative insight into the microstructural origins of rheological effects shown by many complex fluids (e.g. shear-thickening, yield stress, thixotropy, rheopecty) and of transport properties (shear-induced diffusion, mixing and separation). Examples for such complex fluids range from (colloidal and non-colloidal) hard suspensions like fresh concrete, slurries, magneto-rheological fluids, and pastes, to suspensions of deformable objects (e.g. full blood) flowing in complex geometries of any size from microfluidic devices to large mixers. This insight fosters better understanding and allows virtual prototyping of materials in specific applications.
Blood and Cellular Hemostasis
One specific focus of our work lies on the detailed modeling of flow and transport of blood cells in microfluidic and biomedical devices. Our blood models not only fully resolve relevant physics down to the sub-micrometer scale but also include models for cell biochemistry such as for membrane receptors and factors that play an important role in cellular haemostasis. Using these models transport, adhesion, and aggregation of cells in blood vessels and microfluidic and organ-on-a-chip devices can be predicted.
Non-traditional CFD and HPC
We develop state-of-the-art models based on Lattice-Boltzmann Methods (rooted in kinetic theory with deeper physics than just Navier-Stokes) and dynamically adapting rigid-body solvers. High-Performance Computing on parallel computing architectures is an important tool to carry out high-fidelity simulation studies within reasonable times.
