STABILITY OF PNEUMATIC and HYDRAULIC VALVES

There are three forces acting on the valve plate: the force of the escaping air Fv, the force of the steel spring Fs and the pneumatic damping force due to the pressure of the air in the dashpot Fd. Each of these forces varies with distance x. These interact with the valve mass and the pipeline dynamics to produce instability. Perturbations in the pressure travel along the pipe at the sonic vel...

Pneumatic and hydraulic microactuators: a review

The development of MEMS actuators is rapidly evolving and continuously new progress in terms of efficiency, power and force output is reported. Pneumatic and hydraulic are an interesting class of microactuators that are easily overlooked. Despite the 20 years of research, and hundreds of publications on this topic, these actuators are only popular in microfluidic systems. In other MEMS applicat...

Transport efficiency and dynamics of hydraulic fracture networks

Intermittent fluid pulses in the Earth’s crust can explain a variety of geological phenomena, for instance the occurrence of hydraulic breccia. Fluid transport in the crust is usually modeled as continuous Darcian flow, ignoring that sufficient fluid overpressure can cause hydraulic fractures as fluid pathways with very dynamic behavior. Resulting hydraulic fracture networks are largely self-or...
