抄録	For simulations of biological flows, our original immersed solid method and feedback immersed boundary method are coupled to deal with the interaction between a fluid and solids of different dimensional topologies. The mesh used in both methods is non-conforming with respect to the fluid-solid interface, and the coupled approach facilitates the handling of the fluid-structure interaction including large deformation of the solids. We show the validity of our method through simulations of static and dynamic benchmark problems. The results of the simulations confirmed that our method has a first order accuracy and shows good agreement with the strong coupling method reported in the literature. As for examples of biological flow, the expiratory flow through vocal cords and pulsative flow through an elastic channel with fibers are analyzed. For the flow through vocal cords, the vocal cords exhibit different vibration modes depending on the initial clearance of the vocal cords, regardless of the contacts of the vocal cords. For the flow through the elastic channel with fibers, fibers decrease the wall shear stress, and the elasticity of the wall enhances the reduction of the wall shear stress.
