Flow Equipartition and Shape Optimization of Fluidic Channel Networks



Delivering and distributing precise and controlled flows of one or different fluids onto a given surface or into a given volume is a challenge for many unit operations of process engineering. The present chapter is about concepts and fundamentals to conceive, design, optimize and fabricate such devices (fluid distributing/collecting networks), through geometry and hydrodynamic considerations and optimization. Some fundamental questions on optimal shapes and flow distribution in simple systems will be raised. The basic architectures of channel intersecting networks and multi-scale, fractal-like channel networks will be briefly presented, building on analogies with living organisms (e.g. the lung or the vascular system). The theoretical basis of the optimization of such networks will be illustrated on simple examples. A few examples of elaborate designs for complex problems will be given, with the aim of process intensification.
