文摘

PTV study of flow fields of pebble bed reactor with different configurations are carried out. Some criteria are proposed to quantify vertical velocity field and flow uniformity. The effect of different pebble bed configurations is also compared by the proposed criteria. The displacement thickness is used analogically to analyze flow field characteristics. The effect of mass flow variation in the stagnated region of the funnel flow is measured.
