seawater density and temperature

drsidd10 · January 9, 2015, 16:00

I have simulated a tidal turbine blade geometry problem in CFX using SST turbulence model for steady state analysis. I have simulated the current problem for 25C and the seawater density is taken as 1025 kg/m^3.

How does the seawater density and temperature affect CFD simulations?

First, i know nothing about tidal turbines

But if you are interessted in some specific values, why dont you just make a sensitivity check?

Change the density +/-20% and watch what the value your interessted in is doing. Then change the temperature +/- 5K and take a look how it influence your target values.

The answers to a lot of the questions you're asking recently can be found in the CFX theory guide and in text books.

I recommend you read.
