Tip: Using Radial fan in Celsius Thermal Solver

Radial fans displace less air volume and produce more pressure. These fans move the air radially, which can change the direction of the airflow by 90 degrees. Radial fans are suitable for high-pressure settings.

To add a radial fan:

1. Choose Parts > Create Radial Fan.

The Radial Fan dialog box displays.

In the Radial Fan dialog box, specify the settings for the fan’s construction and cooling.

1. In the Construction area, specify a name for the fan in the Name field and enter fan parameters in the following fields:

• Fan Diameter: Diameter of the fan. The default is 40 mm.
• Hub Diameter: Hub diameter of the fan. The default is 20 mm.
• Inlet Width: Diameter of the inlet from where the air will enter. The default is 30 mm.
• Number of Inlet: Number of inlets of the fan. The default is 1.
• Thickness: Thickness of the fan. The default is 10 mm.

2. In the Cooling area:

• Select an appropriate flow rate option from the Flow Rate Option dropdown list

box. The available options are Fixed or Curve.

Fan curve determines the relationship between the fan flow rate and the static

pressure. As the fan flow rate increases, the pressure decreases.

• If you select a Fixed flow rate, you must specify the Fan Flow Rate in the

corresponding field. Fan flow rate is a function of the rotating speed calculated

using m^3/s. The default value is 0.0094.

• If you select the Curve flow rate option, you need to select Fan Curve from

the corresponding dropdown list box.

• In the Heat Dissipated field, specify the amount of heat dissipated by the fan. The default is 0.

3. Click OK.

After the fan is successfully added, it appears under the Parts node as shown below:
