Multiscale modeling of electrospray ion emission
نویسندگان
چکیده
A multi-scale approach to electrospray ion source modeling has been developed. The evolution of a single-emitter plume in pure ionic regime is simulated with combination electrohydrodynamic fluids and n-body particle modeling. Simulations are performed for the liquid, EMI-BF4, firing positive pure-ion mode. metastable nature clusters captured using an fragmentation model informed by molecular dynamics simulations experimental data. Results generated three operating points (120, 324, 440 nA) used predict performance relevant properties, such as divergence angle extractor surface impingement rate. Comparisons data recorded at similar provided.

Multiscale modeling of lithium ion batteries: thermal aspects
The thermal behavior of lithium ion batteries has a huge impact on their lifetime and the initiation of degradation processes. The development of hot spots or large local overpotentials leading, e.g., to lithium metal deposition depends on material properties as well as on the nano- und microstructure of the electrodes. In recent years a theoretical structure emerges, which opens the possibilit...
متن کاملExperimental Studies of Ion Emission from Rpi-ibis Facility and Modeling of Ion Motions
The paper presents the recent measurements of ion beams emitted from an RPI-IBIS plasma injector and some preliminary results of the theoretical modeling. The RPI-IBIS facility was equipped with coaxial electrodes made of thin molybdenum rods and a fast acting electromagnetic valve for the injection of a working gas. Plasma discharges were initiated with a variable time delay (τ ) after the gas...
متن کاملMultiscale Modeling of Malaria
Parasitic infectious diseases like malaria and certain hereditary hematologic disorders are often associated with major changes in the shape and viscoelastic properties of red blood cells. Such changes can disrupt blood flow and, possibly, brain perfusion, as in the case of cerebral malaria. In recent work on stochastic multiscale models—in conjunction with large-scale parallel computing—we wer...
