Abstract

Direct numerical simulation of a coolant flow in a significant portion of the HFIR subchannel is performed at a hydraulic-diameter-based Reynolds number of 70,255. Location based data is gathered and processed for ten locations along the span of the channel to assess curvature effects and boundary conditions on flow parameters. Velocity profiles across the span of the domain are plotted and compared along with turbulent kinetic energy and turbulence dissipation rate. Turbulence statistics are analyzed and presented for different spanwise locations of the domain and compared with flat channel parameters. Results indicate different turbulence levels at the ends of the domain as well as increased velocity on the convex side of the channel compared to the concave side.
