  2. Abstract:
  3. The Computational Fluid Dynamics (CFD) method is employed to gain further insight into the characteristics of the in-cylinder flow field. Comparison between the measured and predicted results of the in-cylinder tumble flow and flow coefficient generated by a port-valve-liner assembly, on a steady-flow test bench, is presented, and a reasonably good level of agreement is achieved. A CAD parametric model of port geometry is created to enable variations, practically and quickly. Employing CFD analysis, the relationship between design parameters and port flow characteristics is established. The inuence of new blockage patterns on in-cylinder flow is also studied
