Abstract
This paper presents discussions on predicting turbulent flows in simple model of engine intake port-valve-cylinder with three port-curvature ratios. The low-Reynolds-number linear k-ε, cubic nonlinear k-e and k-ε-A_2 turbulence models are applied to the flow field computation. The results suggest that the nonlinear eddy viscosity modelling of turbulence is very successful for predicting mass flow rate and in-cylinder velocity distributions.
