Abstract
 Toward a numerical analysis of a drowning process in a water flow, a new numerical flow simulator solving a fluid dynamics and human body motion is developed. The CIP-CUP scheme for a multi-phase flow and the link model for a human body motion are combined. While a human body is modeled as a group of solid bodies, in order to represent a fainting human's motion, a new technique to limit the angle between connected two solids is proposed. The present model is applied to a human drowning in a rectangular pool. The calculation result shows that the present model enables a qualitatively reasonable interactions between human body motion and fluid flow.
