, " and believe that it has identified the R&D needs for NGNP reactor design methods. One of the great challenges of studying, designing, and licensing the NGNP is the successful completion of the tasks that confirm that the intended NGNP analysis tools can be used with confidence to make decisions and to assure all that the reactor systems are safe and(More)
The experimental program that is being conducted at the Matched Index-of-Refraction (MIR) Flow Facility at Idaho National Laboratory (INL) to obtain benchmark data on measurements of flow phenomena in a scaled model of the lower plenum of a typical prismatic gas-cooled reactor (GCR) using 3-D Particle Image Velocimetry (PIV) is presented. A detailed(More)
Boundary layer transition is a critical parameter in the design of fluid flow systems. This situation is due to the dramatic change in both entropy production and heat transfer that accompanies it. It is well recognized that many parameters affect the location of transition onset, however, no models exist which unify all these parameters. This paper(More)
In an earlier paper in Entropy [1] we hypothesized that the entropy generation rate is the driving force for boundary layer transition from laminar to turbulent flow. Subsequently, with our colleagues we have examined the prediction of entropy generation during such transitions [2,3]. We found that reasonable predictions for engineering purposes could be(More)
