tNeedle valve response to input signal is controlled – apart from the dynamics of the driving mechanicalactuator – by interaction of fluidic and mechanic aspects. Despite the long history and ubiquitous useof needle valves, their aerodynamics has never been really systematically investigated. Recent uses forextreme conditions, such as those in the new field of additive manufacturing, put great relevance onaccumulating aerodynamic research data. This third part of a trilogy presents results of pressure mea-surements on internal walls in configurations characterised by rounded needle tip and/or entrance intothe exit channel.
