Deorbiting Dynamics of Electrodynamic Tether
This paper studies satellite deorbit using electrodynamic tether (EDT) propulsion. Gaussian perturbation equations are used to model the orbital dynamics of EDT with environmental perturbations of electrodynamic force, aerodynamic drag and the effect of Earth’s oblateness. Differential equations for the induced voltage-current across EDT are derived and solved with boundary conditions determine...

متن کاملExperiments and direct numerical simulations of two-dimensional turbulence.
Experiments and direct numerical simulations reveal the coexistence of two cascades in two-dimensional grid turbulence. Several features of this flow such as the energy density and the scalar spectra are found to be consistent with well known theoretical predictions. The energy transfer function displays the expected up-scale energy transfers. The vorticity correlation function is logarithmic a...
متن کاملExperiments and Numerical Simulations of Horizontal Two Phase Flow Regimes
Stratified two-phase flow regimes can occur in the main cooling lines of Pressurized Water Reactors, Chemical plants and Oil pipelines. A relevant problem occurring is the development of wavy stratified flows which can lead to slug generation. In the last decade, the stratified flows are increasingly modelled with computational fluid dynamics (CFD) codes. In CFD, closure models are required tha...
متن کاملThermally actuated shape-memory polymers: Experiments, theory, and numerical simulations
With the aim of developing a thermo-mechanically-coupled large-deformation constitutive theory and a numerical-simulation capability for modeling the response of thermally-actuated shape-memory polymers, we have (i) conducted large strain compression experiments on a representative shape-memory polymer to strains of approximately unity at strain rates of 10 s and 10 s, and at temperatures rangi...
