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)
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)
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)
a Decaying Swirling Flow within a Cylinder. Thermally stabilized combustion of premixed ethane and air in a ceramic tube results in a virtual step function in temperature, composition, and velocity at the flame front. If the mixture is fuel-rich, the burned gas consists almost wholly of CO, COz, HzO, and N2. For a tube greater than 30 mm in diameter, the(More)
