Spacecraft rendezvous by differential drag under uncertainties [PDF]
, 2016 At low Earth orbits, differentials in the drag forces between spacecraft can be used for controlling their relative motion in the orbital plane. Current methods for determining the drag force may result in errors due to inaccuracies in the density models

Drag force in SYM plasma with B field from AdS/CFT [PDF]
, 2006 We investigate drag force in a thermal plasma of N=4 super Yang-Mills theory via both fundamental and Dirichlet strings under the influence of non-zero NSNS $B$-field background.

Drag force to all orders in gradients
Journal of High Energy Physics, 2020 We study the energy loss of a heavy quark slowly moving through an evolving strongly coupled plasma. We use the linearized fluid/gravity correspondence to describe small perturbations of the medium flow with general spacetime dependence.

Drag and lift forces when moving in a cohesive granular medium [PDF]
EPJ Web of ConferencesWhen a cylinder moves horizontally in a dry granular medium, it experiences both a drag force and a significant lift force, despite the symmetry of the geometry. The lift force arises due to the unique frictional nature of granular material rheology. The

Collisional Effects on Nonlinear Ion Drag Force for Small Grains [PDF]
, 2013 The ion drag force arising from plasma flow past an embedded spherical grain is calculated self-consistently and non-linearly using particle in cell codes, accounting for ion-neutral collisions.

Hydrodynamic performance of psammosteids: New insights from computational fluid dynamics simulations [PDF]
Acta Palaeontologica Polonica, 2019 The shape of dermal armor protecting the body in the Paleozoic agnathans such as the Heterostaci has an important hydrodynamic role in providing lift or drag force generation.

, 2015 Phonon scattering calculations predict the drag force acting on defects and dislocations rises linearly with temperature, in direct contradiction with molecular dynamics simulations that often finds the drag force to be independent of temperature.

Heavy quark energy loss far from equilibrium in a strongly coupled collision [PDF]
, 2013 We compute and study the drag force acting on a heavy quark propagating through the matter produced in the collision of two sheets of energy in a strongly coupled gauge theory that can be analyzed holographically.
