Microfluidic Valve‐Integrated Garment for Smooth Sequential Gradient Mechanotherapy
Advanced Intelligent Systems, EarlyView.We present a soft wearable sleeve that delivers smooth, gap‐free compression using overlapping air‐filled actuators and tiny microfluidic valves. The system reduces bulk, lowers power needs, and uses a smartphone‐sized control box. It can provide sequential gradient compression, gradient pressure holding, and fast deflation, supporting more portable ...

Depressurization of carbon dioxide in pipelines–Models and methods
Energy Procedia, 2011 AbstractA model for two-phase carbon dioxide transport with phase transfer in pipelines is presented. The stiffened-gas equation of state is used for calculating thermodynamical properties. The convergence and accuracy of two numerical methods–a centred multi-stage (MUSTA) scheme and an upwind Roe scheme–are compared.
