The Landing Platform Dock vessel is mainly designed to support amphibious operations in which landing operations play an important role. For operating landing craft the vessel has a well dock at the stern, designed to station several landing craft. Landing operations are restricted by the motions of the Landing Platform Dock vessel and by the...

Pollution in urban environments is increasingly becoming a major concern for our societies which, together with the increasingly powerful capabilities provided by computational fluid dynamics (CFD), has made pollution dispersion a common topic of research during the last two decades. Several factors are relevant to the dispersion of pollutants...

The need to curb CO2 emissions has led to an increase in the utilization of CCS systems. These systems use pipelines for the transport of CO2. It is preferred that CO2 be transported in it’s dense form. But, this is not always the case as the phase in which CO2 exists is based on the operating conditions. In some cases, multiphase CO2 is...

Nasal airway obstruction (NAO) is one of the most common symptoms in the human respiratory system and causes a considerable financial burden to both individuals and society. Currently, NAO detection is troublesome to achieve, which can influence the accuracy and effectiveness of clinical surgery. Although several objective measurement techniques...

Conventionally, the geometry of the Fri-Jado open vertical refrigerated display cabinet design is optimized by drawing and producing the new components and testing the new configuration in a climate chamber, which is known to be an iterative process that consumes a large amount of time. To speed up the optimization process, the application of...

During the last years the demand for vegetarian products has increased. A subgroup of these vegetarian products consists of meat analogs, which are products that resemble meat in its functionality and are prepared in a similar fashion. One of the companies producing these meat analogs is Rival Foods. Rival Foods has been working on a production...

Aerodynamics has played a significant role in the industry of motorsports in improving the performance and handling of the race car. Rob Smedley, the former head of vehicle performance at Williams Racing stated that - "Where teams have problems is when their development or simulation environment – so CFD [Computational Fluid Dynamics] or wind...

The drainage time of liquid-filled PET bottles can be greatly reduced by pre-rotating the bottle with a certain angular velocity. Depending on the magnitude of the angular velocity, up to four different flow regimes can be distinguished during the emptying of a bottle: bubble regime, transition regime, vortex<br/>regime and the swirl regime. At...

Convective heat transfer finds applications in several domains of industry like heat exchangers, gas turbine blades, IC engine surfaces etc. The surfaces of these heat transfer applications are either naturally rough owing to manufacturing techniques or become rough over a period of time during operation. These rough surfaces usually contain...

Salt intrusion through sea locks causes the mixing of fresh and salt water due to a gravity current. This process may occur gradually over tens of kilometers and affects the required quality of the inland water. A bubble screen alongside the locks is one of the available mitigating measures for this undesired phenomenon. However, current...

In the quest for renewable energy for tropical islands, Ocean Thermal Energy Conversion (OTEC) has revealed itself as one of the most promising technologies. OTEC stands or falls with the performance of the condenser. Plate Heat Exchangers (PHEs) have proven their selves as effective heat transfer<br/>equipment for low enthalpy cycles such as...

An accurate prediction of propeller hull interaction is an important step in the design of a new vessel. The prediction of full-scale flow phenomena, which eliminates scale effects, is becoming available due to increasing computational power. However, the complexity of full-scale CFD calculations combined<br/>with a lack of validation data...

When drilling for oil or gas, wells are typically constructed using a conventional or telescopic well design. After a section of the well has been drilled, a steel casing (or liner) is inserted into the hole preventing the collapse of the hole. The next well section has a smaller diameter as it’s casing must pass through the previously installed...

Many regions in the world depend heavily on expensive desalinated water for fresh water consumption, in particular tropical areas. Current mainstream desalination technologies (Reverse Osmosis and Multi-Stage Flash Evaporation) are quite energy intensive and thus costly. Today’s challenge is to design a desalination system that could run with...

Kottapalli, S. (author)
Flow induced vibrations (FIV) is a known problem in nuclear reactors. The interaction between the turbulent flow of the coolants and the fuel rod bundles generates vibrations which are undesirable. These vibrations can be a major cause of fatigue failures, stress corrosion cracking and fretting wear of materials, which lead to stand-still costs....

This thesis work is a starting point for the Flettner-rotor field of the wind-assisted ship propulsion research of TU Delft and POLIMI. During the development of this project, the flow around a bare spinning cylinder is investigated, introducing the Flettner-rotor without its end plate. The simulations were carried out in 2D and 3D with the...

A study has been performed on the effects of the viscosity of the liquid in the core of core annular flow. This is a multiphase flow regime for two immiscible liquids in a pipe where the high-viscosity liquid forms a core and the other low-viscosity liquid forms a lubricating annulus around the core and along the wall. This is a very efficient...

When looking at domains with several building densities, the resulting average concentrations caused by traffic when unknown, are often linearised between known building densities. To verify if this assumption is correct, several cases of street canyons with intersections, are simulated using the DALESURBAN model. The traffic is represented by a...

Johnstone and Coleman (2012) were among the first to opt the idea of wind farms with mixed tower heights and predicted an increased power production due to the decrease of losses to TKE production from the mean kinetic energy balance. In the current study, the performance of infinite wind farms with alternating tower heights imposed by a...
