Flownex: Creating New Fluid Materials
Hello everyone, if you are using Phalonix and wondering how to add a material with properties not available in the material library, you can add it in the following way. Watch this video for guidance.
Steps to Add a New Material
- In the charts, look up the table.
- Locate the infill solver in the material and filloid section.
- Add a new category if needed. For example, I added a category for petroleum products for a pipeline project involving crude oil transportation.
- Assign a new category and add your desired material. You can rename it or leave the default name.
- Edit the material properties:
- Choose if the material is compressible or incompressible. I selected incompressible for oil.
- Define material properties, which can be constant or parameterized in tabular form, equations, or scripts.
Example: Defining Material Properties for Crude Oil
- Density: 900 kg/m3
- Viscosity: Defined as a polynomial equation in terms of temperature. Assume a linear equation:
- Constant A0: 2.064
- Coefficient A1: -0.006
- Conductivity: 0.06
- Heat Capacity: 2.15 kJ/kg·K
Use the table in the window to define the material properties for crude oil as the operating fluid in this example.
Assigning the Material to a Component
- Return to the component and fellow solver section.
- Add a pipe and a node to define boundary conditions.
- Use the newly defined material for flow control in fluid systems.
- In the pure materials section, select the new category or the previously created petroleum product category, such as crude oil.
Thank you very much for watching.
Title: Flownex: Creating New Fluid Materials Hello everyone, if you are using Phalonix and wondering how to add a material with properties not available in the material library of Phalonix, you can add it in this way. Watch this video.
In the chart, look for the "Infill Solver" in the material and filloid. You can add here, for example, if you consider your material as a pure filloid, you can add a category here.
I already added a category here for myself that it is for petroleum products because I'm working on an example for pipelines for transferring crude oil. Here you can see that I already assigned another category and here I can add my material that I want.
I can rename it; I just leave the name as given here and then edit that here I can add the properties that I want. First, I have to choose if my material is compressible or incompressible. I just leave it as incompressible because oil is incompressible.
Now I can start to add the material properties here. Every material property could be constant or be defined in terms of some parameters as in tabular form or in an equation or using a script for that. For example, here I use a density of 900 kilogram per cubic meter.
I want to have my viscosity in terms of temperature instead of being constant. I can use an equation for that as a polynomial. You can see that I can define my material's viscosity in terms of temperature. I need to define what the equation for that is.
Suppose I just consider that it is just a linear equation.
Okay, so I need to enter the values for these two constants, A0 and A 1. For the constant value, I use 2. 064. And for the coefficient A1, I use -0. 006. So as you can see, I just consider a linear variation of the temperature of the viscosity in terms of temperature.
Then I can go for conductivity and add a value of 0. 06. For heat capacity, I can again consider that it is constant and consider that it is 2.15 in terms of kilojoule per kilogram per Kelvin. So 2. 15. If I need to, I can go for the rest of the properties. But here I don't need to.
So basically, I use this table in this window to define the material properties for the crude oil that I want to use as my operating fluid in this example. Now I can use the material as I already defined here and assign it to a component. Back to component and flow solver.
Solver, suppose I add a pipe here as you can see, and also in nodes and boundaries, I add a node that is used to define the boundary conditions. Here I can use the material that I newly defined. As you can see, this is for flow control. Okay, for fluid, this is what we already saw, pure materials.
In the pure materials, I added two categories. As you can see, I showed you in this video and the one that I already created before. For the new one, I can choose this one or for the another category, petroleum product. I can use crude oil. Say okay.
So I assign and use this new material that viscosity or function of temperature for this component. Thank you very much.
