Leading Innovation in Kinetic Particle Deposition
ÖRG is active in building multiphysics and multiscale models and building innovative experimental platforms for the development of processes for high-throughput additive manufacturing using kinetic particle deposition (KPD). KPD enables the solid-state deposition of microscale particles by means of kinetic impact energy achived through the acceleration of particles in supersonic spray nozzles.
HIGH VELOCITY MULTIPHASE FLOWS
Studying the physics pertaining to the motion of particulates in high velocity turbulent multiphase flows.
High Reynolds number jet impingement Phenomena
Understanding the physics of high Reynolds number supersonic impinging jets and their interactions with flat and featured surfaces. Development heat transfer models to represent unique flow regimes.
Process Quality Assurance & Control
Standardization of powder feedstock characterization methods for predictable spray procedures.
Nondestructive of AM Products
Development of training programs and educational materials for engineers & technicians
Predictability and Reliability of Flow Based AM Processes
Wear & clog resistant nozzles.
In-situ sensory systems and machine learning algorithms
High-fidelity CFD and heat transfer models for accurately simulating Cold Spray, Wire Arc Additive Manufacturing, and Plasma Arc Additive Manufacturing for machine process optimization
