I am working on pressurized liquid heat transfer related problems. I got correct flow regimes for heat transfer at atmospheric pressure. Now I need to pressurize the fluid more than 300Bar and analyse how the heat transfer occurs. Even though we approximate liquids to be in-compressible, beyond 300bar the volume reduces hence the change in density comes into picture. how to model this in Ansys? What should be given in density column in material properties of liquid? I tried with compressible-liquid option and I am not getting correct flow regimes. I should find how the transfer occurs at elevated pressure ranges. Need your help!!!
Thanks
Dear friend Immanuel Keba J
To model pressurized liquid heat transfer in ANSYS Fluent, you will need to follow these steps:
It's important to note that modeling compressible liquids can be more complex than incompressible ones and requires additional consideration for pressure variations and their effects on fluid properties. You may also need to use a more complex turbulence model to accurately capture the flow regimes at high pressures. Therefore, it's recommended to consult with an expert or study related literature to ensure proper set up of the problem.
Dear Kaushik Shandilya,
Grateful for your detailed answer. I am familiar with all the points you have mentioned except the first one. As you've suggested I m receiving assistance from ANSYS technical support team to solve this problem. But not yet solved. Could you please guide me how to incorporate the EOS models in ANSYS Fluent? I mean, where to start and how to implement that model in ANSYS? I have a hydraulic oil having different properties. Is there any such EOS available for hydraulic oils to predict it's properties at elevated pressures and temperatures? Need your inputs
Thanks
