The turbulent flow field generated in a baffled stirred tank was computed by large eddy simulation (LED) and the flow field was developed using the Sliding Mesh (SM) approach. In this CFD study, mixing times and power number have been determined for a vessel agitated by a 6-blade Rushton turbine. The predicted results were compared with the published experimental data. The satisfactory results ...

We present two modiications of continuum models used in large eddy simulation. The rst modiication is a closure approximation which better attenuates small eddies. The second modiication is a change in the boundary conditions for the large eddy model from strict adherence to slip with resistance. For model consistency the resistance coeecient is a function of the averaging radius so that the mo...

This paper focuses on the use of reinforcement learning (RL) as a machine-learning (ML) modeling tool for near-wall turbulence. RL has demonstrated its effectiveness in solving high-dimensional problems, especially domains such games. Despite potential, is still not widely used turbulence and primarily flow control optimization purposes. A new wall model (WM) called VYBA23 developed this work, ...
