The ability to elicit distinct duty cycles from the same self-regulating microfluidic oscillator device would greatly enhance the versatility of this micro-machine as a tool, capable of recapitulating in vitro the diverse oscillatory processes that occur within natural systems. We report a novel approach to realize this using the coordinated modulation of input volumetric flow rate ratio and fl...

The demand for eco-friendly technologies for industrial processes is increasing. Various factors such as labour costs, exploitation and waste management influences the production costs and hence the profit generated. The water treatment industry is one example of a well-developed sector which is facing these concerns. Microbubble techniques exhibit many benefits which make them applicable to he...

In this report we propose a sensor architecture and a corresponding read-out technique on silicon for the detection of dynamic capacitance change. This approach can be applied to rapid particle counting and single particle sensing in a fluidic system. The sensing principle is based on capacitance variation of an interdigitated electrode (IDE) structure embedded in an oscillator circuit. The cap...

We investigate the onset of temporal dynamics a fluidic oscillator (FO) in laminar regime at very low Reynolds number (Re=Uhi/ν, where U and hi are velocity channel height inlet, ν is kinematic viscosity fluid). Both two- spanwise-periodic-three-dimensional simulations performed using high-order spectral element methods to characterise flow inside FO cavity outcoming jet. While remains steady s...

The internal heat transfer performance and flow structures of a sweeping jet film composite cooling on flat plate were numerically studied. Sweeping consists fluidic oscillator 20 cylindrical holes; the direct is formed by removing feedback from oscillator, which different traditional nozzle.
