    Pump in simulation loop. Converting test to flow simulation.

    Jakis Test

      Hallow everyone

      I want to simulate my PC water cooling system in SolidWorks symulation.

      At the moment I have problem with recrieting pump in system.

      At the moment I made closed loop with internal fun to generate flow.

      My problem is:

      I do not rally know how to simulate pump at the moment.

      Pump in the system was tested on this forum:

      Official product info for EK D5 pump:

      - Maximum pressure head: 3.9m

      - Maximum flow: 1500L/h

       

      Is this correct way to test pump for SolidWorks simulation.

      If so How can I convert it to usable data?

          I understand that to get proper parameters (pressure difference) to simulate pump in loop, I would need to add other inlet of the manometer before the pump?

          Is that correct?

              Hi Jakis,

              Are you still working on this simulation? What you need for your model is an internal fan. This is from the official online help documentation, available inside the software:

               

              Creating a Fan

              Allows you to simulate a fan as an ideal device creating a volume (or mass) flow rate. The dependency of the volume or mass flow rate on pressure as well as other fan parameters are specified in the Engineering Database.  You can apply the fan to model faces representing inlet and outlet openings closed with lids (see How It Works). You can use a Fan in both Internal and External flow analyses. For more information see Fans - Basic Information.

              You can visualize specified fans directly on the model: colored arrows indicate the direction and type of condition. Right-click a fan item in the Flow Simulation analysis tree and select Show or Hide to turn on or turn off the arrows.

              To create a fan:

              1. Click Fan on the Flow Simulation Features toolbar or Tools > Flow Simulation > Insert > Fan.

              - or -
              In the Flow Simulation analysis tree right-click the Fans item and select Insert Fan.

              1. Under Type select the fan type:
                • External Inlet Fan. This type of fan creates an inlet flow into the model and acts as an inlet boundary condition. Specify the External Inlet Fan condition for the internal face of a lid closing an inlet opening, where a fan is originally installed in the model.

                • External Outlet Fan. This type of fan creates an outlet flow from the model and acts as an outlet boundary condition.  Specify the External Outlet Fan condition for the internal face of a lid closing an outlet opening, where a fan is originally installed in the model.
                • Internal Fan. This type of fan simulates an internal fan within the model, with one selected set of faces acting as the inlet and other set acting as the outlet. Since both sides of an Internal Fan are in contact with the fluid within the computational domain, the fluid static pressure difference between the sides governs fluid passage through the fan in accordance with characteristics of the selected fan.
              2. Select faces for which you intend to specify the fan condition:
                • For an External Inlet Fan, in the graphics area select faces on which you intend to specify the fan. The selected faces appear under Faces fluid exits the fan, in the Faces to Apply list.

                • For an External Outlet Fan, in the graphics area select faces on which you intend to specify the fan. The selected faces appear under Faces fluid enters the fan, in the Faces to Apply list.
                • For an Internal Fan, under Faces fluid exits the fan click the Faces to Apply list and select faces at the outlet side of the fan in the graphics area, then under Faces fluid enters the fan, click the Faces to Apply list and in the graphics area select faces at the inlet side of the fan.

              See Selection List for details.

              If you want to remove faces of a specific type from the selection list, click Filter Faces . See Selection Filter for details.

              1. Under Faces fluid exits the fan and Faces fluid enters the fan you can also select a reference coordinate system, if you intend to specify either a fluid swirl or 3D velocity vectors, or non-uniform flow parameter distribution over the selected faces:
                • The reference Coordinate System selected by default can be:

                • Face Coordinate System (for single planar faces). The origin of face coordinate system is located at the center of the face and its X axis is oriented normally to the face.
                • Global Coordinate System (for non-planar faces or if more than one planar face is selected).
                • You can replace the default coordinate system by selecting your coordinate system in the flyout FeatureManager design tree. To create a coordinate system, click Insert > Reference Geometry > Coordinate System.
                • If you want to specify a different fan axis or use a cylindrical coordinate system, select an axis of the specified Coordinate System as the Reference axis list. The selected Coordinate System and Reference axis also define a local spherical coordinate system. See Dependency for details.
              2. Under Fan select the fan from the list of pre-defined and user-defined fans available in the Engineering Database. If you want to add a new fan to the Engineering Database or edit an existing one, click Create/Edit to open the Engineering Database. The fans can be defined in the Engineering Database by Fan Curves or as Axial or Radial fans.
                See Fans - Basic Information for details.
              3. Under Options select the Create associated goals check box if you want to create goals associated with the selected type of fan. Flow Simulation allows you to associate a fan type with some specific goals, and these associated goals will be created together with the fan. You can associate goals with a fan type under the Automatic Goals item in the Flow Simulation Options dialog box.
              4. If you want the fan in a time-dependent analysis to toggle on/off depending on time or a goal, under Toggle click Dependency . Note that a goal-dependent fan can influence the calculation convergence.
                See Dependency.
              5. Specify fan parameters, which are not included in the fan definition in the Engineering Database.
                See Specifying Fan Parameters.
              6. Click OK . The new fan item appears in the Flow Simulation Analysis Tree.
                To edit definition of a fan, in the Flow Simulation analysis tree, double-click the fan item, or right-click the item and select Edit Definition.
                Also you can use a callout in the graphics area to edit definition of a fan.
