Aside from Turbulence Intesity and Length (I - L) and Turbulent Energy and Dissipation (k - e) turbulent models can I add other turbulent models. See the attached file (png file) under dialog box turbulence parameters.
"poor prediction" could be a relative term, until you run the analysis using the tool and compare against test data, it is hard to say it isn't a fit for your analysis. if you're trying to improve the design, even if you're using kE, you'll be able to see relative improvements between the systems. i have a feeling that a good first step would be to use flow simulation.
negative, that is the model used by flow simulation
why do you want to use a different turbulence model?
Thanks Jared for the reply, I really appreciated it. As I researched about the turbulent model (k-e) via this website(http://www.bakker.org/dartmouth06/engs150/10-rans.pdf), please take a look at these site. The site discuss about the advantages and disadvantages of different turbulent models (please see page 29 of 47).
I am currently simulating a helical pipe heat exchanger, and It involves heat exchange in rotating and swirling flows, which gives a poor prediction using the turbulence model (k - e) used by the solidworks. By the way, k-e turbulent model is also called as STD (standard) k-e turbulence model because of its simplicity and robustness.
I wanted to used different turbulent model like RNG k-e turbulence model (please see page 46 of 47 of the link site - which gives a summary of different turbulence models) which offers a good prediction for simulating swirling flows.
I hope that in the future these turbulence models (based on the site) will add up to the flow simulations of Solidworks.
