The Generation IV Very High Temperature Reactor (VHTR) design is being actively
studied in various countries for application due to its inherent passive safe design,
higher thermal efficiencies, and proposed capability of providing high temperature
process heat. The pebble bed core is one of two core designs used in gas reactors. In
the pebble bed core there are mechanisms present which can cause the flow to
laminarize, thus reducing its heat transfer effectiveness. Wind tunnel experiments were
conducted using Particle Image Velocimetry (PIV) to investigate boundary layer
laminarization due to flow acceleration and convex curvature effects. The flow was
subject to acceleration and curvature both separately and together and the flow behavior
characterized with velocity flow profiles, mean boundary layer parameters, and
turbulence quantities. Laminarization was identified and the influence of acceleration
and curvature was characterized. / Graduation date: 2013
