1 Introduction 2 Usual K-epsilon models 3 Miscellaneous 4 References Introduction The K-epsilon model is one of the most common turbulence models, although it just doesn't perform well in cases of large adverse pressure gradients (Reference 4). It is a two equation model, that means, it...
Note to OpenFOAM users: do not confuse this constant with the one used in their implementations of the k-epsilon turbulence models. Their implementation is different. References See sectionReferencesin the parent pageK-epsilon models. Log in...

1.The effects of the gap between the driver cab and the freight body of the heavy-duty truck on its aerodynamic characteristics were simulated by means of a simplified truck model ground transportation system(GTS) using the RNG k-ε turbulence model and hybrid mesh technique.以简化的大型载货汽...
K是湍流脉动动能(J),ε(epsilon)是湍流脉动动能的耗散率(%) k-ε模型直接的好处是对于平板和圆柱射流的发散比率的更精确的预测。而且它对于旋转流动、强逆压梯度的边界层流动、流动分离和二次流有很好的表现 K 越大表明湍流脉动长度和时间尺度越大,ε 越大意味着湍流脉动长度和时间尺度越小,它们是两个量制约着...

Difference between K-epsilon and K-omega Turbulence Model May 11, 2018 at 7:46 pm Burhan Subscriber I am doing simulation of "Vortex Tube" in which compressed air swirl through out the body. 1-Which Model can I use (k-e or k-w) ? I want to converge result fast. Suggest me briefly...
The SST k-omega turbulence model is a two-equation eddy-viscosity model that is used for many aerodynamic applications. It is a hybrid model combining the Wilcox k-omega and the k-epsilon models. A blending function, F1, activates the Wilcox model near the wall and the k-epsilon model in...
I am using single phase turbulent k-epsilon model to do so. However, I get pressure drops higher than expected. I suspect that the turbulence damping that occurs for these flows is not being implemented. Does anyone have suggestions or experience with this matter? I could use a few pointers...
K-Epsilon Model #1 sangit Guest Posts: n/a Hi, I am a student of TU Munich Germany. And I am a novice in CFD. I am studying the k-epsilon turbulence model and using 2 equation of this model to simulate flow inside a pipe. I am discritisizing the two differential equations of k ...
