Assessment of intermittency transport equations for modeling transition in boundary layers subjected to freestream turbulence

Mechanisms of surface pressure distribution within a laminar separation bubble at different Reynolds numbers

“…In terms of H 45 The H 0.7x/c at lower Reynolds number cases considered in this study are close to the value of the laminar boundary layer and H 0.7x/c of higher Reynolds number cases are slightly higher but close to those of the turbulent boundary layer. Another evidence is that the time-and spanwise-averaged velocity profiles at lower Reynolds numbers at 0.7x/c from the leading edge shown in Figure 8 follow closely to u + = y + , suggesting the laminar boundary layer.…”

Correlations for modeling transitional boundary layers under influences of freestream turbulence and pressure gradient

“…The transition length parameter, F length , is displayed against e Re ht on a semi-logarithmic scale. The valid relation of F length with Re ht is found to be an open zone for the boundary layer flow with Tu > 1% ð e Re ht < 500Þ, and then become a single line for the boundary layer flow with Tu < 1% ð e Re ht > 500Þ (Suluksna and Juntasaro, 2008). The expression for F length decreases exponentially with e Re ht .…”

Internal flows which transist from turbulent through intermittent to laminar

“…Very recently, the Menter model was compared with two other external-flow transition models by Suluksna and Juntasaro [20], who found that it provides the closest representation of experimental data for a number of test cases. This model was further developed by the present authors [21] to extend its applicability to internal flows.…”
