The movies have been taken at 4000 fps. The spark is placed at a distance z from the nozzle and at 5mm from the enclosure. The ignition unit delivers at 100Hz a spark lasting 8ms, followed by 2ms of no activity. The front ...

Ink-jet printing of nano-metallic colloidal fluids on to porous media such as coated papers has become a viable method to produce conductive tracks for low-cost, disposable printed electronic devices. However, the formation ...

This research is about the development of a photocatalytic reactor design, Honeycomb, for in-situ groundwater remediation. Photocatalysis, typically a pseudo first order advanced oxidation process, is initiated via the ...

Jet breakup is strongly affected by fluid rheology. In particular,small amounts of polymer can cause substantially different breakup dynamics compared to a Newtonian jet, influencing in-flight fragmentation and detachment ...

Abstract Background Public-private partnerships (PPPs) are potential instruments to enable private collaboration in the health sector. Despite theoretical debate, empirical analyses have thus far tended to focus on the ...

This paper attempts a synthesis of theoretical and empirical work on international financial contagion. Although a professional consensus on the appropriate definitions of contagion has yet to emerge, we document substantial ...

This report is a complement to the PhD thesis entitled "Simulations of turbulent swirl combustors". This work extends the application of the Large Eddy Simulation/ Conditional Moment Closure approach developed in the ...

The state of the ink film at and near the nozzles of a drop-ondemand(DoD) print head during jetting has a direct impact on printing performance and reliability. We have developed highspeed imaging apparatus and analytical ...

Semi-Markov models are a generalisation of Markov models that explicitly model the state-dependent sojourn time distribution, the time for which the system remains in a given state. Markov models result in an exponentially ...

This research project aims at providing the aeronautical industry with a modelling capability to simulate the fuel injection in gas turbine combustion chambers. The path to this objective started with the review of ...

This work evaluates the capabilities of the RANS and LES techniques for the simulation of high speed reacting flows. These methods are used to gain further insight into the physics encountered and regimes present in ...

This paper provides an historical analysis of the four privatization stages of the Russian economy covering the period 1986-2005 with particular attention to the initial period of private capital formation. We use data ...

The assessment of ageing tunnels requires a deeper understanding of the long-term behaviour of twin tunnels, whilst lack of permeability data limits the accuracy of long-term predictions. This thesis therefore investigates ...

Some research in the area of make-buy decisions for new technologies suggests that it is a good idea for a company to pursue a fairly rigorous “make” policy in the early days of a potentially disruptive innovation. Other ...

This thesis investigates mean reaction rate closures for turbulent reacting flow. The closures model the mean rate of reaction in the flow and are applied to simulations of nanoparticle formation. The simulations couple ...

The turbulent boundary layer is an aspect of fluid flow which dominates the performance of many engineering systems - yet the analytic solution of such flows is intractable for most applications. Our understanding of ...

The influence of stratification on the structure of turbulent methane/air combustion is investigated using experimental data from laboratory scale burners: a weakly turbulent slot burner, and a higher turbulence co-annular ...
