Abstract

This study presents a control method for a water flow to avoid seaweed twining in a cultivation pool. The water flow in the pool is modeled by the lattice Boltzmann method. Morphology of the seaweed is determined by L-system. Physics modeling (PM) represents its physical model. Three physical properties, gradual collision, adhesiveness, and tear phenomenon for the seaweed are artificially introduced into simulation. Motion of the seaweed is examined in the virtual underwater pool by PM simulation. A water flow pattern is realized by controlling particles distributed in lattices. We ascertained that some water flow pattern is useful to avoid the seaweed twining phenomenon by changing the water flow pattern in the simulation.
