What's it like!
 

I work in hydraulic consultancy. There has been talk of using Solid works and Flowworks.

What is flow works like at modelling three phase flows (e.g. air, water, grit).

Your comments would be appreciated

Hi Jamie

As far as I know, FloWorks cannot model 3-phase flows. What size range of particles are you interested in? (by grit I am assuming that you are interested in small particles). The particle size will determine the required modelling approach, and hence ultimately the choice of code.

Thank you Imraan, for your reply,

We are interested in anything from negative (grits) and neutral byuoyancy (organic) to positive buoyancy (floc).

So which code is preferred for which particle size?

Hi Jamie

So you are trying to model dispersed phases (air/grits/organics/flocs) in a primary phase (water)? From my limited knowledge of multi-phase flows, you could use a Lagrangian Dispersed Phase Model, a mixture model, or a Eularian multi-phase model. Each of these models have various pros and cons in terms of accuracy and computational expense.

These types of problems are not a strongpoint of the current version of FloWorks/EFD, so I think that you may have to look elsewhere for a solution to your problem. Possible alternative solutions might include Fluent, Star-CD, CFX and OpenFOAM. I am sure that there are other packages that would also work. In the end, it all depends on what information you want to extract from your models and the level of accuracy you require for this information. Anyway, hope this helps.

Thanks, Just as I thought,

I think we shall stick with Fluent!
