Membrane gas absorption processes are absorption processes utilising hollow fibre membranes as contacting media for gas and liquid flows. The principle of operation and engineering aspects are discussed, followed by discussion of a number of typical applications. Benefits in terms of operation, efficiency and costs are shown to exist for a...

Tyres determine to a great extent the dynamic behaviour of road vehicles. The mechanical characteristics of the tyre in contact with the road combined with the mechanics of the vehicle produce operational characteristics of the tyre-vehicle system which should guarantee vehicle stability to the driver. Therefore an accurate description of the...

More tight environmental legislation makes it necessary to develop new separation technologies that operate not only very efficient but also flexible. In many cases retro fit installations are required which put also constrains on volume and weight of the equipment to be installed. Membrane gas absorption is a new technolog with such interesting...

This paper will discuss the DELFT-TYRE productline from the point of view of the engineer to optimize operationai cha¡acteristics of the tyre-vehicle system. Several examples are treated to illustrate the added value of sophisticated tyre modelling under combined slip conditions (braking in a turn) and the use of scaling factors in the...

The sensitivity of vehicle handling to combined slip tyre characteristics is investigated using two simulation models with different interaction between lateral and longitudinal tyre forces. The standard method for the braking in a turn test is simulated with both models, and differences in the outcome are related to tyre characteristics. The...

The influence of several road characteristics like longitudinal and transverse evenness and skid resistance are always evaluated separately on the aspects comfort and/or safety. This passes over the influence these surface characteristics can have in combination on riding comfort and safety. This paper describes the way these characteristics are...

Membrane gas absorption for carbon dioxide production from flue gases is discussed with special reference to the economics of the supply of carbon dioxide to greenhouses in the Netherlands. Novel absorption liquids have been introduced which show as excellent performance in terms of system stability and mass transfer when used in combination...

The risk analysis to select the preferred basic tunnel design for the tunnels in the High Speed Train Link South from Amsterdam to Antwerp is described. The risk analysis has been split up in two stages: a broad qualitative risk analysis and a quantitative risk analysis. The results of the qualitative risk analysis for the 7.2 km bored Green...

For efficient analysis it is important to choose the proper model that fits the problem that needs to be solved. This paper discusses three pragmatic simulation models for longitudinal behaviour of a passenger car tyre (steady State, Transient and Rigid Ring) that may be used in e.g. an ABS simulation. The characteristics of the simulation...

Combi-Road is a new transport concept for containers that has been developed in The Netherlands. For the transport of containers, an unmanned automated guided vehicle is used that runs on a dedicated track. This paper discusses the development process of the vehicle guidance- and communication system. The various systems have been developed in...

Membrane gas absorption is a new, efficient and flexible way to carry out gas-liquid contacting operations with hollow fibre membranes. Advantages of gas absorption membranes over conventional G-L contactors are: -High specific surface area and rapid mass transfer resulting in very compact and low weight equipment; -Gas and liquid flow are...

The first results are presented from a quantitative model describing the aerosol production in the surf zone. A comparison is made with aerosol produced in the surf zone as measured during EOPACE experiments in La Jolla and Monterey. The surf aerosol production was derived from aerosol concentration gradients measured downwind from the surf zone...

The objective of this paper is to present a systematic modelling approach to vehicle handling simulation, validation and optimisation. Moreover, special attention will be paid to the use of mathematical tools for the development of a passenger car with active rear wheel steering for yaw motion control. Several models for the vehicle as well as...

In recent years, at the Delft University of Technology and TNO Automotive and in conjuction with an industrial consortium, a pragmatic tyre model has been developed going by the name SWIFT, which is geared to the analysis of tyre oscillations and its effects on vehicle behaviour. The SWIFt tyre model has been designed to cover in-plane, out-of...

River gravel used as aggregate for concrete in the Netherlands contains several potentially deleterious components with respect to alkali-silica reaction (ASR), viz. porous chert, chalcedony, and impure sandstones (greywackes. mica- and sericite-rich sandstones, siltstones, arkoses etc.). Whereas cherts and chalcedonies are virtually free from...
