Add a Fluid Load node to describe loads from the fluid on the pipe. Three types of loads can be entered: Internal pressure, drag force from the fluid, and centrifugal forces in pipe bends.
Enter the Internal pressure, pi. The list contains any pressure variables announced by other physics interfaces, as well as the option
User defined. For
User defined, enter a value or an expression for the internal pressure.
For User defined, enter a value or an expression for the external pressure.
Select a method for entering the Drag force per unit length,
Fd. The choice
User defined is always available, in which case you enter a value or expression in the text field. A positive load acts in the same direction as the positive direction of the edge to which the load is applied. To visualize edge orientations, select
Show edge direction arrows in the appropriate
View node.
The Drag force per unit length list can also contain drag force variables announced by the Pipe Flow interface.
Select a method for entering the Centrifugal force per unit length,
Fc. The choice
User defined is always available, in which case you enter values or expressions in the text fields. In the
User defined case, the input is similar to using an
Edge Load.
The Centrifugal force per unit length list can also contain drag force variables announced by the Pipe Flow interface.
