Fatigue is a gradual process of local strength reduction. It is a phenomenon of damage accumulation at stress concentrations caused by fluctuating stresses and/or strains. In metals this results in microscopic cracks. These will start to grow under continued cyclic loading until final failure occurs. The process of fatigue is essentially a...

The aim of the present study is to set up a one-dimensional mathematical model, which describes the transient flow in pipelines, taking into account the influence of cavitation and free gas. The flow will be conceived of as a three-phase flow of the liquid, its vapour and non-condensible gas. The wave attenuation following transient cavitation...

Door de steeds strenger wordende eisen op het gebied van energiezuinigheid van gebouwen, neemt de aandacht voor nieuwe materialen en vernieuwende installatieconcepten toe. Eén van de concepten die een belangrijke rol spelen bij energiezuinige gebouwen is de opslag van warmte voor de korte (enkele uren of dagen) dan wel de lange (enkele maanden)...

The aim of this research project was (i) to obtain an understanding of the destratification process caused by the local injection of air at the bottom of a thermally stratified lake or reservoir, and (ii) to make possible quantitative predictions of the rate of destratification in a given situation. To this end a mathematical model was set up,...

When designing a pipeline for the transport of a liquid one of the problems to be considered is the provision of a device to guard against low pressures. These low pressures can be caused, for example, by a sudden pump failure. The failure creates a negative pressure wave which travels in the downstream direction. Vapor pressure may be reached...

Experiments on mixed-layer deepening in a straight wind flume initially containing a two-layer fluid were carried out. In order to simulate an effectively unlimited water body, or a situation where the presence of end walls is not yet noticeable, the water from the upper layer was withdrawn at the downstream end, and supplied again at the...

BESTAND A BEVAT HET HOOFDRAPPORT EN BESTAND B BEVAT DE BIJLAGEN Voor het optimaal beladen van sleephopperzuigers is het belangrijk om inzicht te hebben in de processen die plaats hebben in het beun van een sleephopperzuiger. Een van de deel-processen is het bezinken van zand in een hoog geconcentreerd zandwater mengsel onder invloed van...

A mathematical model has been considered in which the influence of gas release on transient cavitating flow and column separation in pipel ines is taken into account. A rei iable numerical method has been developed for the computation of the wave propagation and cavitation phenomena following pump fai lure, valve closure, etc. Good agreement has...

Wanneer in een vat een korrelvormige vaste stof met een vloeistof wordt gemengd en de dichtheid van de vaste stof groter is dan die van de vloeistof, zal de stof bezinken. In dat geval zullen er na verloop van tijd boven een bepaald niveau in het vat geen deeltjes van de vaste stof voorkomen waarvan de valsnelheid groter is dan de afstand van...

The settling velocities of fine sediments can be determined using a sedimentation balance essentially consisting of a settling tube at the bottom of which the weight of the sediment deposited is measured as a function of time. The distribution of settling velocities then is calculated from an equation, which is known as Oden's formula. In this...

A derivation is presented of a general cross-section averaged model of longitudinal dispersion, which is based on the notion of the advection of tracer particles. Particle displacement length and particle travel time are conceived as stochastic variables, and a joint probability density function is introduced to arrive at an integral advection...

Dit rapport geeft een beknopte analyse van de verdunning en verspreiding van zout vanuit een gepland depot voor ontzilt zeezand in het Haringvliet. Beschouwd zijn de initiële menging van het zout bij terugwinnenvan het zand, de verspreidingdoor stroming en turbulentie bij geopende spuisluis, en de verspreidingten gevolge van door wind...

Bij het transport van vloeistof van een reservoir naar een ander kan de configuratie van het transportsysteem bestaan uit reservoir-pomp-bufferschacht of windketel-leiding-reservoir. Indien de pomp uitvalt, treedt een terugslagklep tussen bufferschacht of windketel en pomp in werking, die voorkomt dat de vloeistof terugstroomt naar het...

A mathematical model describing the unsteady stratified settling of sediment samples and nonuniform suspensions has been developed, taking into account the influence of the sediment concentration on the fall velocity. In principle, the resulting equations can be solved using the method of integration along characteristics. An estimating...

This report presents computational results concerning the buoyancy-driven leakage of oil resulting from a possible rupture of the planned pipeline P/15-4 to Hook of Holland. The computations were commissioned by R.J. Brown and Associates (Netherlands) b.v. (RJBA Job No. 7004.02). The specifications of the pipeline and oil as made available by...

Mathematical and physical modelling makes possible quantitative predictions regarding the destratification process brought about by the local injection of air at the bottom of a thermally stratified lake or reservoir. The mathematical model developed distinguishes between a near field and a far field. Mixing of epilimnion water and hypolimnion...

In this article some field observations, made in recent years, of internal wave motions in a density-stratified estuary are presented, In order to facilitate the appreciation of the results, and to make some quantitative comparisons, the relevant theory is also summarized. Furthermore, the origins of stratification in estuaries is briefly...
