Minisymposium Title: Active Polar Gels
Minisymposium Description: The hydrodynamic equations of active polar gels model the continuum, macroscopic mechanics of a collection of uniaxial active agents, embedded in a viscous bulk medium, in which internal stresses are induced due to dissipation of energy. The energy-consuming uniaxial polar agents are modeled by a polarization field, which is governed by an equation of motion. The relationship between the strain rate and the stress in the fluid is provided by a constitutive equation. These equations, along with conservation of momentum, provide a continuum hydrodynamic description modeling active polar viscous gels as an energy consuming, anisotropic, non-Newtonian fluid. Within this minisymposium we will discuss modeling aspects, various applications and numerical issues.
