Universal Thermal Radiation Drag on Neutral Objects [PDF]
, 2003 We compute the force on a small neutral polarizable object moving at velocity $\vec v$ relative to a photon gas equilibrated at a temperature $T$ We find a drag force linear in $\vec v$.

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

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 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.

On the rise and fall of a ball with linear or quadratic drag [PDF]
, 1999 We review the problem of a vertically thrown ball, with a drag force which is either linear or quadratic in the speed. It is stressed from the outset that these two types of drag correspond to specific ranges of the Reynolds number ...

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.

Drag force on an oscillating object in quantum turbulence
, 2009 This paper reports results of the computation of the drag force exerted on an oscillating object in quantum turbulence in superfluid $^4$He. The drag force is calculated on the basis of numerical simulations of quantum turbulent flow about the object ...
