Eddy viscosity hypothesis versus Reynolds stress models
As time progresses computing power also increases. Just compare the power of desktop computers nowadays to 5 or 6 years ago.
Taking this into consideration why aren't more and more people using the Reynolds stress models as apposed to eddy viscosity models?
Surely the computational cost of Reynolds stress models is decreasing making them an attractive alternative to the Eddy viscosity models.
The reason I ask this question is because I've read recent papers (2011 and 2012) where the authors have used two equation models to model strong anisotropic flows, where in my opinion the Reynolds stress models would be better suited.
Am I missing a trick?
