CFD Simulations for the Water & Process Industry

Collection of CFD simulations carried out for different applications in the water and process industry.
Unsteady CFD simulation is the most effective way to analyze dynamic processes involving fluid flow.
Typical applications for CFD in the water & process industry are:
+ mixing in stirred tank reactors
+ flow distribution analysis
+ heat transfer in stirred reactors
+ hydraulic calculations
+ analysis of particle suspension
+ analysis of sedimentation problems
+ analysis of aerated tanks and oxygen transfer efficiency
+ etc.

Any workbech step by step video available?

Could you please put the complete toutrial in ansys fluent for this type of mixer

Hi, i have a problem for a numerical simulation of agitated vessel (MRF method) Pre Processing CFX 15.0; can you help me please ?
DOMAIN INTERFACE: Domain Interface 1
Boundary List1 = Domain Interface 1 Side 1
Boundary List2 = Domain Interface 1 Side 2
Interface Type = Fluid Fluid
INTERFACE MODELS:
Option = General Connection
FRAME CHANGE:
Option = Frozen Rotor
END
MASS AND MOMENTUM:
Option = Conservative Interface Flux
MOMENTUM INTERFACE MODEL:
Option = None
END
END
PITCH CHANGE:
Option = None
END
END
MESH CONNECTION:
Option = GGI
END
END
In Analysis 'Flow Analysis 1' - Domain Interface 'Domain Interface 1': The interface is placed at a rotor-stator interface and the pitch change option of 'None' has been selected. This option should only be used when the overall extent and shape of each side of the interface perfectly match and the surfaces are aligned with each other. It may therefore be suitable when full 360 degree or exactly equal pitch components are being analyzed.

In Analysis 'Flow Analysis 1' - Domain Interface 'Domain Interface 1': Pitch Change option 'Automatic' is not valid if side 1 or 2 of the interface has a 360 degree or greater pitch angle, zero radius, mesh faces normal and parallel to the rotation axis, or mesh faces at the hub curve (low radial or axial position) which are thin in the radial or axial direction.

Are these all with Large Eddy Simulation?

[@thinkfluiddynamix4834]

Hi! for some simulations we have used "Detached Eddy Simulation", which is a mixture between LES and RANS approach. LES is still too expensive to be used in large scale engineering projects. The only LES simulation we have done was this one: ua-cam.com/video/lkVfbJmWhk4/v-deo.html

[@thinkfluiddynamix4834]

some simulations are modeled with "Detached Eddy Simulation", another with RANS

For mixing of two fluid in tank and simulation in ansys, video available?

Which simulation software you are used for this type of simulation??
