Sulphur removal in the ironmaking and oxygen steelmaking process is reviewed. A sulphur balance is made for the steelmaking process of Tata Steel IJmuiden, the Netherlands. There are four stages where sulphur can be removed: in the blast furnace (BF), during hot metal (HM) pretreatment, in the converter and during the secondary metallurgy (SM...

Purpose In orthopaedics, minimally invasive injection of bone cement is an established technique. We present HipRFX, a software tool for planning and guiding a cement injection procedure for stabilizing a loosening hip prosthesis. HipRFX works by analysing a pre-operative CT and intraoperative C-arm fluoroscopic images. Methods HipRFX simulates...

Voor een locatie in het centrum van Rotterdam, direct aan de Verlengde Willemsbrug en de Blaak, heeft architectenbureau Kraaijvanger•Urbis een ontwerp gemaakt voor de woontoren Domuslokatie. Vanwege de moeilijke vorm van het kavel, blijkt het vrij lastig om de parkeervoorzieningen (op traditionele wijze) efficiënt in het ontwerp op te nemen....

Master project report. In the year 2004 there was a flooding in an area between Da'an River and Dajia River in Taichung County, Taiwan. The flooding was caused by outlets which were clogged up, thus lacking the capacity to discharge the amount of rainwater that the typhoon caused into the sea. A survey conducted by the project group, showed that...

On the basis of a simple analysis of boundary layer properties it is argued that skin friction reduction in adverse-pressure-gradient (but attached) boundary layers does not necessarily leads to viscous drag reduction.

Measurement techniques in low-speed turbulent flows were discussed at the EUROMECH 202 Colloquium at NLR in Marknesse, The Netherlands, October 7-10, 1985. A total of 54 participants from 9 countries attended, and 38 papers were given in two sessions, each closed with a general discussion.

Three-dimensional shear layer experiments are discussed with a view to those developing calculation methods. The emphasis is on the selection of useful experiments for comparisons with calculations and the proper way to perform the comparisons. A review of more recent three-dimensional shear layer experiments is included.

The results of several three-dimensional turbulent boundary layer calculations have been compared with each other and with experiment for a number of test cases. The calculation methods applied range from integral methods to field methods using a turbulence model based upon the Reynolds stress transport equations. The test cases comprise various...

The symposium demonstrated the importance of research in the area of mechanical high-lift systems for transport aircraft to improve the total performance of current transports. Computational techniques are shown to provide new tools for high-lift design. With regard to drag reduction by laminar flow control it is concluded that the information...

The turbulence transport equations are reviewed. The role of the pressurestrain term is studied. It is shown that the pressure-strain term exactly cancels the production term when the Taylor hypotVjesis or frozen turbulence approximation holds. The consequences of this result foi[ the interpretation of the turbulence transport equations are...

The transport equations for the six turbulent stress tensor components are discussed, with particular emphasis on the terms containing turbulent pressure fluctuations. The conventional separation of the pressure fluctuation terms is argued. A more logical separation is proposed.

At NLR a system for the computational design on multi-element airfoil has been developed. This design system solves the inverse aerodynamic problem in an approximate way. A priori specified aerodynamic requirements (surface pressure distribution) and geometric requirements are minimized in a least-squares way, introducing weight factors to...

A computational method is presented for threedimensional turbulent boundary layers. The turbulence model is a simple eddy-viscosity formulation. An hybrid difference scheme is used, which has the robustness of first order schemes and accuracy of second order schemes. The boundary layer is computed in the region of determinacy of the initial data...
