Abstract: The three-dimensional two-equation k–ω turbulence model is applied to obtain the characteristics of flow past a rectangular floor slot located in a rectangular closed conduit. The predictions of the numerical simulation are validated using existing experimental data. The model faithfully reproduces the flow behavior including flow separation in the expanding flow region downstream of the slot. In particular, the model predictions agree well with the experimental data related to pressure and velocity fields. As such, following proper model validation, the numerical model can yield design data pertaining to flow characteristics for different discharge ratios and slot width ratios for many other slot flow situations encountered in engineering practice.
