Nozzle Design in Cold Spray Applications

Julio Gutierrez (Materials Technology, HSU) In cold spray, the critical velocity defines the minimum velocity that the particles must reach in order to adhere to the substrate. The more particles exceeding this critical velocity, the higher are the efficiency of the process and the deposit quality. Individually needed process conditions…

Density Functional Theory Calculations of Positron Lifetimes

Marcel Dickmann (Applied Physics & Measurement Technology, UniBwM) Positron Annihilation Lifetime Spectroscopy (PALS) is a powerful method to investigate open-volume defects like vacancies or vacancy clusters in crystalline materials. The occurrence of atomistic defects has a major influence on material properties, such as electrical conductivity or magnetic and optical characteristics.…

Single machine scheduling with position dependent maintenance

M. Sc. Andreas Hipp (Chair of Business Administration, HSU) Machine wear and tear is a typical problem that must be dealt with in real-world production environments. In scheduling research since the 1980s, time-dependent deterioration is usually identified as the main factor for machine wear. In our work, we focus on…

The 2-stage no-wait hybrid flow shop scheduling problem

M. Sc. Andreas Hipp (Chair of Business Administration, HSU) Hybrid flow shop (HFS) scheduling problems as a flow shop production layout adding parallel machines on at least one stage of operation represent popular systems in real-world production environments.  In our work, we focus on the no-wait HFS scheduling problem. The…

Monte Carlo simulations of real fluids

Univ.-Prof. Dr.–Ing. Karsten Meier (Chair of Thermodynamics, HSU) Thermodynamic properties of gases and liquids over wide ranges of temperature and pressure can be determined by molecular-dynamics or Monte Carlo simulations. In such simulations, the interactions between molecules are almost exclusively modeled by simple effective pair potentials, such as the Lennard-Jones potential. With such…

Enabling High-Throughput Studies of Reactive Materials

Christopher Lange (Department of Mechanical Engineering, HSU) The project aims at establishing an optimized simulation framework for the atomistic modeling of impact-induced chemical reactions in new weapon materials. In our mechano-chemical research we combine atomic and molecular dynamics simulations. Strain-dependent reaction paths are determined with static ab initio simulations and coupled…
