Flow Simulation in Engine Cylinder with Spring Mesh
This investigation presents results from numerical simulation of the air flow in Spark Ignition Engine (SI engine) cylinder. Accurate modeling of the flow in cylinder is a key part of successful combustion simulation. The most usual numerical method in Computational Fluid Dynamics (CFD) is finite volume. In this investigation an important, common fluid flow patterns in CFD simulations, namely, Tumble motion typical in automotive engines and RNG k-ε turbulence model were used. The air flow in a two-valve engine cylinder during 720 degree of crank angle was investigated by using a CFD code which is basis on finite volume and codes which were written in visual C++ environment. Dynamic Mesh and Moving Boundary capability were used for this model. The comparison results with previous researches results, Kiva-3v and PIV experimental, show good agreement.
