Apparent Transition Behavior of Widely-Used Turbulence Models
The Spalart-Allmaras and the Menter SST k-ω turbulence models are shown to have the undesirable characteristic that, for fully turbulent computations, a transition region can occur whose extent varies with grid density. Extremely fine two-dimensional grids over the front portion of an airfoil are used to demonstrate the effect. As the grid density is increased, the laminar region near the nose ...
متن کاملLow-dimensional models of subcritical transition to turbulence
In the past five years, working largely independently, five groups of researchers have proposed low-dimensional models of the behavior of parallel shear flows at high Reynolds numbers. These models are compared, and it is found that they are more similar than their authors have recognized. Among other similarities, most of them exhibit a threshold amplitude e 5 O(R) as R→` for some a,21, where ...
متن کاملToxicity of Certain Widely Used Antiseptics
1. The substances injected intraperitoneally into mice and guinea pigs arranged in the order of their decreasing toxicity are: eucalyptol and brilliant green; mercurophen; mercuric chloride and chloramine-T; dichloramine-T and proflavine; hychlorite, Dakin's hypochlorite, Javelle water, and magnesium hypochlorite; iodine and phenol. 2. Now that Dakin's bland solvent, chlorcosane, is available a...
متن کاملUse of Stochastic Turbulence Models in Jet Acoustics
There are many approaches to determine the sound propagated from turbulent flows. In hybrid methods, the turbulent noise source field is computed or modeled separately from the far-field calculations. To have an initial and quick estimation of the sound propagation, less computationally intensive methods can be developed using stochastic models of the turbulent fluctuations. In this paper, ...
متن کاملConstructing transition models of AI planner behavior
Evaluation and debugging of AI systems require coherent views of program performance and behavior. We have developed a family of methods, called Dependency Detection, for analyzing execution traces for small patterns. Unfortunately, these methods provide only a local view of program behavior. The approach described in this paper integrates two methods, dependency detection [10] and CHAID-based ...
