An aerodynamic model of the collisional alignment of the cations of macromolecules

Resumo

The collisional alignment of macromolecule ions in an external electric field was studied based on the scaling of the dimensions and properties of a real macromolecule and its environment into the domain of classical mechanics. The calculations were carried out within the framework of computational fluid dynamics for a streamlined prolate spheroid macromolecule; they showed that the collisional alignment of ions occurred in an oscillatory mode with a characteristic time of several nanoseconds.
