Abstract
This paper presents a topology poptimization method for fluid dynamics problems, based on the level set method and using the lattice Boltzmann method (LBM). The LBM is a new approach for calculating viscous fluid behavior that replaces the classical formulation employing the Navier-Stokes equation. We inprove the optimization method which Yaji and others suggested, introduce the linear interpolation boundary condition into boundaries between fluid and solid domains. In this way. even few elements can perform good analysis of the precision, and it is excpected that memory and calculation time are reduced. Through a numerical example, we have confirmed the efficiency of the proposed method.
