Power Transmission and Motion Control (PTMC 2005)
Current developments in fuel injection, variable engine
valve actuation systems, and related fields of technology result in an increasing demand for accurate and fast simulation methods for fluid flow in networks of small pipelines or bores within valve manifolds.
Besides the description of the flow in straight pipes,
the understanding of the influence of elbow fittings,
branch connections, intersecting bores, and the like is
crucial for an accurate prediction of the dynamic behaviour. While there is a vast literature on the steady state pressure drop of hydraulic components, the dynamic case is poorly understood even for pulsatile laminar flow. The paper gives experimental results on the input output behaviour of test case including a single pipeline with a concentrated flow resistance at the connection between the pipe and a cavity of comparatively large diameter as well as minor
concentrated losses due to the mounting points of pressure sensor. Results are given in the form of frequency response functions up to 2 kHz for the test case with a pipe length in the order of one metre.
