Dynamic Behavior of Complex Fluid-Filled Tubing Systems—Part 2: System Analysis

Abstract

The pipe segments modeled in Part 1 are incorporated into a larger scheme permitting branching, fittings, valves, added masses, rigid, flexible and dissipative mechanical constraints, accumulators and various boundary conditions. The concept of the global matrix also is extended to systems with junctions and closed loops, permitting practical solution for frequency responses without round-off error problems. The procedure can be generalized to handle a broad class of systems comprising a combination of lumped elements and quasi one-dimensional distributed-parameter elements. A complex example with experimental corroboration is given.
