1D simulation query

[Hari]

WAVE is an 1D package. But what does 1D simulation essentially mean? I heard in 1D case, the fluid flow equations are reduced to one dimension. But I cannot comprehend this. Can anybody explain it elaborately.

Many Thanks

I don't know what WAVE is, but 1D is analysis along a single axis. An example of 1D analysis is deformation of a rod.

deformation = PL/AE

Or average tensile stress = P/A

The easy way to think of it is essentially wave breaks up ducts (pipes, tubes, passages, volumes etc) into short segments.

These pieces each have the fluid mechanics equations solved across them for their give properties (ie the diameter of the duct is fixed for that section of duct). If you segment the duct into enough "elements" it enables the software to numerically solve the equation and creates a model for the entire network.

The 1D refers to the fact that each element only has one axis of fluid flow.
