Flownex: Fluid Network
Hello everyone, in this video, I will demonstrate how to create a simple fluid network using Flownex. We will work in the component form to set up the network.
Setting Up the Fluid Network
- Click on the piping section and choose a pipe to place in the network.
- Define the boundary conditions by specifying the inlet and outlet nodes.
- Add nodes to connect more pipes, forming a network.
- For each pipe, use a node to define boundary conditions, such as pressure and temperature.
Defining Pipe Specifications
To enter the properties of a pipe, press the F4 function button. You can specify:
- Length and units
- Diameter (ensure correct units)
- Wall roughness and K values for loss calculations
Adding Containers
You can add a tank or a reservoir from the containers section. Ensure it is connected to the network.
Boundary Conditions
Define boundary conditions at the two ends of the network:
- Pressure: 1500 kilopascal
- Temperature: 20 degrees Celsius
For another section, you can set:
- Lower Pressure: 100 kilopascal
- Higher Temperature: 40 degrees Celsius
Always check the units for the parameters you enter.
Pipe and Container Specifications
- First Pipe: 35 meters in length, 0.5 meters in diameter, 40 microns wall roughness
- Second Pipe: 250 meters in length, same diameter and wall roughness
- Third Pipe: 70 meters in length, same diameter and wall roughness
- Container Volume: 100 cubic meters
Running the Network
Run the network to observe changes in pressure, temperature, and mass flow rate. The steady-state solution will provide results in the console.
Results and Observations
In the console, you can observe:
- Pressure drop from 1500 kilopascal to 100 kilopascal
- Temperature change from 20 degrees to 4 degrees Celsius
- Conservation of mass flow rate
- Velocity consistency due to uniform pipe diameter and no loss consideration
Hover over each network element to see calculated results such as:
- Total mass flow: 2259.17 kg/s
- Total volume flow rate: 2.53245 m³/s
Accessing Detailed Results
Click on a pipe to view detailed results, including:
- Pressure
- Temperature
- Total mass flow rate
- Volume flow rate
Summary
In this video, I demonstrated how to create a simple fluid network using Flownex. We connected pipes using nodes, defined boundary conditions, and added a reservoir. We specified pipe characteristics and ran the network for a steady-state solution, reviewing results in the console.
Thank you very much.
Hello everyone in this video I want to show you how to create a simple fluid network in Flownex. First, click on piping and choose a pipe, then place it. Next, add nodes for inlets and outlets and define the boundary conditions. You can add more pipes and nodes as needed.
To define the properties of a pipe, select it and press F 4. Here, you can enter the length, diameter, and roughness, as well as define losses. You can also add a tank or server from the containers menu. To define boundary conditions, click on the network and add them at the desired locations.
For example, you can set the pressure and temperature at the inlet and outlet of the network. Additionally, you can assign specifications for each pipe, such as length, diameter, and roughness.
Once you have set up the network, you can run it to see the resulting changes in pressure, temperature, mass flow rate, and other parameters. You can also view detailed results for each element in the network by hovering over it or clicking on it and viewing the results tab. Thank you for watching.
