Random wave and current forces acting on an offshore structure, cause random base shear forces in time. The peak base shear is the maximum value of base shear that occurs during the passage of a wave. The extreme base shear is the maximum value of base shear that occurs within a period of time, say one hour. So far, the distributions of extreme...

In this study research is performed into the accuracy of flood estimation. In particular the rivers on the island of Java are considered. For these distinctive rivers, the GAMA I unit hydrograph theory was developed (Sri Harto 1985) for flood estimation. The GAMA theory defines 3 basic characteristics to represent a unit hydrograph; time of rise...

Ocean waves are random and their crests evolve non-linearly. Yet commonly used wave models correctly incorporate only one of these aspects: the models either use non-linear regular wave theory whilst ignoring the randomness or use linear random theory with empirical corrections close to the free surface. For the more realistic design and re...

In deze simulatie-studie is onderzocht in welke mate het schutwaterverlies beperkt kan worden door een aanpassing in de bediening van de sluis. Op kanalen en gekanaliseerde rivieren spelen steeds meer belangen een rol, met elk hun eigen waterbehoefte. Peilhandhaving, behoud van natte natuurwaarden, drinkwatervoorziening, water ten behoeve van de...

Steam pyrolysis of ethane and naphtha is an important chemical bulk process. It produces ethylene and propylene, which are important base chemicals. In order to be competitive, crackers have to be operated at near optimal conditions. Hence, a simulation program of the process, particularly of the pyrolysis is very helpful. KTI uses and licenses...

The shipping company CSAV wants a new harbour to be built in Golfo de Arauco in Chile. The bay is situated directly south of the city Concepcion. DMC designed a layout for this harbour. Along the coast of Chile tsunamis can occur. The design made by DMC does not reckon with this phenomenon. In this report at first a review of the harbour layout...

For several years the Department of Physical Geography ofthe University of Utrecht has conducted surveys on the river Allier in France. These surveys always took place during periods of low discharge because at high or even moderate discharges measurements are impossible. As information on the flow during a flood is important to understand the...

In the tidal inlets in the Dutch Wadden Sea, the most important sediment types are sand, silt and clay. A distinction between the sediment types is made, because clay particles have cohesive properties. Consequently, the clay particles do not behave as individual particles but tend to stick together. Floes are formed whose size and settling...

HTM is a major role player in the public transportation sector of the Netherlands with its tram and bus services. The company is continually working to improve their infrastructure management policies by considering aspects such as vehicle priorities, driver allocation and vehicle schedules. One obstacle in the way of HTM’s continual improvement...

The use of smart well technology to optimize water flooding introduces a large number of control parameters both in space (well segments) and time. The problem of finding the optimal control parameters to maximize net present value as an objective function can be solved with the aid of a gradient-based optimization method. Using too many...

Within the Dow Chemical Company the strategy is to centre process flowsheet design activities around the simulation tool Aspen Plus (from Aspen Tech Inc.). However, the model library of Aspen Plus is limited in type and number of models of process unit operations. Equation oriented modelling tools, such as gPROMS (from Process Systems Enterprise...

Recently, Calo [V.M. Calo, Residual-based multiscale turbulence modeling, PhD thesis, Stanford University, 2004] devised the so-called residual-based variational multiscale (RB-VMS) formulation for large-eddy simulation, that uses both the scale separation and the coupling terms in the variational multiscale equations. Using arguments from...

Delfi-C3 is a nanosatellite developed by MSc students of the Faculty of Aerospace Engineering and Electrical Engineering, Mathematics and Computer Science at the Delft University of Technology. It will serve as an in-orbit test bed for three innovative technologies. Delfi-C3 is scheduled for launch in August 2007 by an Indian PSLV launcher. This...

In this MSc thesis project, an effort was made to predict the mechanical properties (especially the tensile strength and stiffness) and crack propagation of cement paste using 3D lattice fracture model at the micro-level. This project consists of three modules, namely “3D Lattice Generation”, “3D Lattice Analysis” and “Interpretation of results”...

Fractional-flow theory provides key insights into complex foam IOR displacements and acts as a benchmark for foam simulators. In some cases with mobile oil present the process can be represented as a two-phase displacement. We examine two such cases. A first-contact miscible gas flood with foam injection includes a chemical shock defining the...

Carbonated water flooding (CWF) is an enhanced oil recovery method where an oil reservoir is flooded with water containing dissolved CO2. The CO2 is then transferred into the oil phase leading to the swelling of the oil and to the reduction of its viscosity. This method was proven by several field trials but did not reach the status of a routine...

Fixation of uncemented implants is known to be more problematic than cemented implants as the proces relies on the growth of bone into the porous implant surface. This bone growth determines the fixation of the implant and has been the subject of many investigations [1-6]. A literature survey [7] revealed that these models are either a highly...

Thesis deals with finite element (FE) simulation of borehole jack (BHJ) tests in ice. The purpose of the thesis was to simulate elastic-plastic range shown in BHJ tests, compare measured ice stiffnesses with obtained from simulations, fit plastic range, investigate plastic properties and stress descending in surrounding ice. Eight BHJ tests...
