Effect of membrane bending resistance on capsule wrinkling in simple shear flow
Abstract eng: We study the effect of wall bending resistance on the motion of an initially spherical capsule freely suspended in shear flow. The fluid–structure interactions are modeled by coupling a boundary integral method for the fluids with a shell finite element method for the capsule envelope. For a given wall material, the capsule deformability strongly decreases when the wall thickness (or bending resistance) increases. For low flow strength, membrane wrinkles can appear with a wavelength that depends on the wall bending resistance.
