The overall aim of our research is to understand and control the structure and dynamics of soft matter at interfaces in dimensions ranging from nano- to macroscale and engineer new functional materials. A key aspect of our research is the preparation of well-defined molecules, materials, emulsions and surfaces, which leads to desired function. 3D printing presents a groundbreaking approach to fabricating microfluidic devices, enabling the construction of microchannels with complex geometries. This technique allows for controlled outputs on the scale of tens of micrometers, facilitating the creation of fully three-dimensional channels and intricate surface modifications. Compared to traditional microfluidic fabrication methods, 3D printing enhances parallelization, screening capabilities, and mass production efficiency. It is widely applicable to various liquid-based processes, including micromixers, solution exchange, filtration, and droplet microfluidics. Computational Fluid Dynamics (CFD) is an indispensable tool for numerically analyzing and predicting fluid behavior, enabling the study of complex flow phenomena as well as thermal and mass transport across multiple scales. Our research leverages high-performance computing and diverse numerical methods to address challenges in fluid mechanics and uncover transformative insights. In real-world systems, multifaceted flow regimes—spanning laminar, turbulent, single-phase, and multiphase flows—frequently coexist. Through CFD simulations, we replicate these intricate dynamics with high fidelity, providing insights that are difficult to achieve experimentally. This approach improves predictive model reliability for design parameters such as flow distribution, pressure drops, temperature gradients, and concentration profiles
