1. Sound generation in metal flue organ pipes: On the influence of asymmetric flue exit geometry and vibrations of the upper labium with particular emphasis on the early response
Abstract : Sound generation in flue organ pipes is caused by the non-linear interaction between an instable jet and a tube resonator. Our understanding of this very complex physical process is still incomplete, and there is not yet a model that can explain all details of the richness in pipe sound which can be achieved by a trained organ pipe voicer.

2. A study on axially rotating pipe and swirling jet flows
Abstract : The present study is an experimental and numerical investigation on rotating flows. A special facility has been built in order to produce a turbulent swirling jet generated by a fully developed rotating pipe flow and a Direct Numerical Simulation (DNS) code has been used to support and to complement the experimental data.

3. Study on Metallic Melt Coolant Interactions and Debris Bed Formation in a Water Pool
Abstract : To assess corium coolability during severe accidents of LWR, significant number of studies have been conducted previously to investigate the characteristics of debris beds formed from FCI due to fragmentation of molten corium and settlement of the fragments in a water pool. However, their focus has been placed on the oxidic component (UO2/ZrO2) of corium, while little attention has been paid to the debris bed formation due to FCI of the metallic component (Zr/Fe) of corium.

4. Polyelectrolyte complexes : their preparation, adsorption behaviour and effect on paper properties
Abstract : In this work, the formation of polyelectrolyte complexes (PECs) has been studied using a jet mixing method not previously used for mixing polyelectrolytes. The PECs were formed from two weak polyelectrolytes, i.e. READ MORE

5. Injection and Combustion of Alternative Fuels in Spark Ignited Direct Injection Engines
Abstract : Increasingly stringent vehicle emission legislation necessitates increasingly efficient combustion engines. The use of direct injection in spark ignited engines improves engine efficiency and reduces CO2 emissions. READ MORE
