Main Title: Simulation of the point-mass-loaded filament in the homogeneous turbulence
Author(s): Cho, Moonsung
Type: Video
Abstract: The passive dynamics of a ballooning spider in the chaotic flow motion of atmosphere is important to understand its suspension capability. To model a ballooning silk that is suspended in the air flow, we introduce the bead-spring model. Each bead is connected to the other with a tensile and a bending spring. By adjusting each stiffness value, we can simulate various extensibility and flexibility values of a filament. A point-mass, which means a spider body is attached to one end of the filament. The video shows an example of the simulation in the homogeneous turbulence. The color means absolute velocities of the surrounding flows.
