How to define a mixture of water and gas in the flow simulation,i am giving an input of air at one end of the pipe.
And there is an other inlet through which water will be entered into the pipe.
I want to find out the outlet temperature at other end of the pipe.
Can the tracer study module be used for finding the temperature at the other end?
Please do share your suggestions.
Thanks and Regards,

Hi
Thanks for the inputs. In this problem, the air is main fluid flowing at high temeprature, to reduce its temp. the water is injected with certain pressure before the exhaust, which is at atmosphere. The purpose is to check the temp. of fluid at the exit. It is not important to find the chnage of phase of water. How best we can address this.
Will tracer study help me in this regard?

tracer and particle studies are post processes, they just "follow" your initial flow stream, they don't influence it
your only option would be to create a gas (same speices) that simulates your water injection so that they mix
and if it really is an injection, you're talking about transient analysis, otherwise it will be flowing constantly.
Hi Jared,
Thanks for the reply.
I have copied the properties of the water and defined it in the gas as a user defined entity and i have perfomed the flow simulation.
Do the air and water mix inside? If the volume of each changes (if any point inside the tube changes from being full of air to full of water) Flow will not solve for that change. It can mix gases with gases or liquids with liquids, but it does not re-mesh to handle change of matter.
