Analytical model for electrohydrodynamic thrust [PDF]

open access: yesProceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2020
Electrohydrodynamic (EHD) thrust is produced when ionized fluid is accelerated in an electric field due to the momentum transfer between the charged species and neutral molecules. We extend the previously reported analytical model that couples space charge, electric field and momentum transfer to derive thrust force in one-dimensional planar ...

ANALYTIC MODELING OF STARSHADES [PDF]

open access: yesThe Astrophysical Journal, 2011
External occulters, otherwise known as starshades, have been proposed as a solution to one of the highest priority yet technically vexing problems facing astrophysics - the direct imaging and characterization of terrestrial planets around other stars. New apodization functions, developed over the past few years, now enable starshades of just a few tens

Analyticity in Hubbard Models [PDF]

open access: yesJournal of Statistical Physics, 1999
The Hubbard model describes a lattice system of quantum particles with local (on-site) interactions. Its free energy is analytic when t is small, or t^2/U is small; here, is the inverse temperature, U the on-site repulsion and t the hopping coefficient. For more general models with Hamiltonian H = V + T where V involves local terms only, the free

SVC Dynamic Analytical Model [PDF]

open access: yesIEEE Power Engineering Review, 2002
This paper presents a linear state-space model of a static VAr compensator. The model consists of three individual subsystem models: an AC system, a SVC model and a controller model, linked together through d-q transformation. The issue of non-linear susceptance-voltage term and coupling with a static frame of reference is resolved using an artificial ...
