Hose dialog - Coolant Flow tab

This dialog is used to specify the heat in the mold in contact with the hoses, for a Coolant Flow analysis.

Note: For optimum heat transfer, make sure the coolant flow is turbulent, and the temperature difference between the initial and return coolant temperatures does not exceed 4° F.

To access this dialog, select a Hose element, then either select Edit (Geometry tab > Properties panel > Edit), or right-click and select Properties from the drop-down menu. Select the Coolant Flow tab.

Enter a unique, descriptive name to save the hose heat transfer properties. Deselect Apply to all entities that share this property if you only want the changes to apply to the elements you have selected.

Note: Always use the Hose property rather than the Connector property when modeling cooling channels.

Explanation

Heat Transfer option

The default setting is zero flux, meaning that the fluid in the element has no interaction with its surroundings and is perfectly insulated. For this default case, the coolant temperature stays constant, unless different inlets have different coolant temperatures. In this case, mixture effects are considered.

To simulate the temperature of the coolant at any given location, enter select an element at that location and enter a value for one of these options.

Flux: Constant flux in W/m²
Total Heat: Total heat in kW. Use the equation Q = (m × C_p × dT) ÷ cycle time, where, m is the mass of the part, C_p is the specific heat capacity of the plastic, and dT is the difference in temperature from the plastic at the start, to the temperature you would like it to be.
Temperature: If the mold is being held at a constant temperature, enter the value in ^oC
