Institute for Fluid Mechanics and Aerodynamics (SLA), Technical University of Darmstadt
- Conducted high-resolution CFD simulations to investigate the impact behavior of individual liquid droplets on solid surfaces
- Applied moving mesh techniques to accurately resolve droplet shape, contact line dynamics, and deformation during impact
- Developed and optimized adaptive mesh refinement (AMR) strategies to ensure numerical stability under large deformations
- Analyzed key transient phenomena including droplet spreading, retraction, and secondary droplet formation
- Investigated thermal effects by modeling temperature both as a passive scalar and through dynamic thermal–fluid coupling

Research assistant | PhD student
Institute for Fluid Mechanics and Aerodynamics (SLA), Technical University of Darmstadt
- Performed CFD studies in industrially relevant geometries (e.g., heat exchangers, jet engine components, drilling systems, journal bearings)
- Developed and applied an eddy-resolving Reynolds Stress Model with near-wall sensitivity for advanced turbulence resolution
- Analyzed the impact of wall rotation and transverse curvature (convex/concave) on turbulent structural properties
- Implemented and validated a coupled Euler–Lagrange multiphase model in one-, two-, and four-way coupling regimes
- Conducted a systematic parametric study of particle-laden annular flows, focusing on multiphase flow regimes and interaction mechanisms
Summary
I am currently working as a postdoc in the field of droplet impact and grid optimization with a focus on flow-thermal couplings.
I have in-depth knowledge of OpenFOAM, ANSYS Fluent, thermal analysis and interdisciplinary research.
