Hi,
I am modeling a water flow in pipe. I need to specify the speed of sound. My questions are the following: 1. Can I enter the speed of sound in FLUENT as a specific value or not? How? 2. Is that need to use a UDF? How? 3. If it was calculated by FLUENT (not entered directly), how can I make sure that the determined value is correct? Can I see it? 4. Is that require to define the flow as "compressible" (ideal gas)? |

Hai,
I am not sure about your application and the need for incorporating the speed of sound in the simulation. normally u calculate the mach number of the flow and determine whether the flow is compressible or incompressible and make simulations based on that. |
