An 1D-3D Integrating Numerical Simulation for Engine Cooling Problem 2006-01-1603

The combination of 1D and 3D fluid flow models is achieved using a co-simulation methodology. This realizes that the internal flow in a component simulated in 3D is incorporated into a network (system) containing components represented in 1D. This methodology gives the details of the internal flow while conserving overall mass flow in the system, thus eliminating uncertainties in boundary conditions prescribed in the 3D model and reducing the overall simulation time. This paper shows numerical results for internal flow of water flow circuit of engine cooling system and availability and current problem of 1D/3D co-simulation method are discussed.
