抄録

<p>We develop a method to simulate fluid flow near a road tunnel portal with driving cars using an open-source computational fluid dynamics solver OpenFOAM. We employ sliding mesh and Arbitrary Coupled Mesh Interface (ACMI) functionality to realize motion of cars relative to the tunnel. We also employ mapping functionality to realize continuous simulation; the result of simulation with sliding mesh is mapped to the following step of simulations as the initial flow field. Boundary conditions for interface between fixed and sliding meshes are discussed. 2-dimentional flow fields near the tunnel portal with or without driving cars are simulated successfully.</p>
