Technologies based on computational fluid dynamics (CFD) have been developed to many new fields, such as generating scenes in computer games, computer animation and Hollywood movies. In this paper, the application of CFD to the computer simulation of tissue bleeding, which is one important part of developing a surgical training system based on virtual reality technology, is investigated. One real-time bleeding simulation model based on CFD is proposed aiming at realistic simulation of tissue bleeding. Navier-Stokes equations are applied to model blood flow as an incompressible fluid. A faster solution to the Navier-Stokes equations is employed to solve the density field and velocity field in order to develop a real-time system. In light of this solution, a tissue bleeding model with OpenGL has been implemented. The results show that this method applied to the bleeding simulation is elucidating and practical.
