Orbit Decomposition Method for Rotordynamic Coefficients Identification of Annular Seals
Applied Sciences, 2021 The elliptical orbit whirl model is widely used to identify the frequency-dependent rotordynamic coefficients of annular seals. The existing solution technique of an elliptical orbit whirl model is the transient computational fluid dynamics (CFD) method.

Dynamics of charged dust in the orbit of Venus [PDF]
Astronomy & Astrophysics, 2021 We study the dynamics of co-orbital dust in the inner Solar System, that is, the role of the solar radiation pressure, the Poynting-Robertson effect, the solar wind, and the interplanetary magnetic field, on the location, width, and stability of resonant motion of charged and micron-sized dust grains situated in the 1:1 mean motion resonance with Venus.

Orbit Dynamics in Isochronous Cyclotrons [PDF]
IEEE Transactions on Nuclear Science, 1981 Acceleration of heavy ions in an isochronous cyclotron can lead to a ..nu../sub r/-value near unity for many turns. In ORIC, several departures from 3-fold symmetry unfortunately exist, so that a complex resonant behavior may lead to beam loss. To study these questions, a program has been initiated with the aim of devising and using very efficient ...

Dynamical Friction and Orbit Circularization [PDF]
Symposium - International Astronomical Union, 1987 We study the change in shape of the orbit of a satellite sinking (because of dynamical friction) towards the center of a larger galaxy. the galaxy is assumed spherically symmetric with distribution function either isotropic or predominantly radial. the satellite is a softened point mass.

Orbital and equilibrium dynamics of a multiwell potential
Results in Physics, 2022 We consider a Hamiltonian system associated with the two-well umbilical catastrophe potential D5, while the corresponding potential contains only one free parameter. We determine how this free parameter affects the equilibrium dynamics of the system by computing their coordinates on the configuration plane, along with their linear stability and type ...

Solving Coplanar Power-Limited Orbit Transfer Problem by Primer Vector Approximation Method
International Journal of Aerospace Engineering, 2012 The coplanar orbit transfer problem has been an important topic in astrodynamics since the beginning of the space era. Though many approximate solutions for power-limited orbit transfer problem have been developed, most of them rely on simplifications of
