When addressing urban heat problems, climate- conscious urban design has been assuming that urban water bodies such as canals, ditches or ponds cool down their surroundings. Recent research shows that this is not necessarily the case and that urban water bodies may actually have a warming e ect, particularly …

This research has been conducted to analyze the current water production process and see if improvements in terms of energy efficiency is possible by using the optimal configuration for different sailing profiles. Water consumption on cruise vessel is higher than on non-passenger vessels. Freshwater …

The Dutch Transmission System Operator (TSO) TenneT TSO B.V. is planning to build a 2 km to 4 km long 150 kV superconducting cable connection in the Dutch high voltage grid. Superconducting cable systems allow for connections with no external magnetic field which is beneficial due to society's concerns …

Lake Source Cooling (LSC) is een relatief nieuwe methode om op een duurzame manier groene energie te winnen. Bij LSC wordt koud water uit een plas of meer op grote diepte onttrokken en via een warmtewisselaar wordt koude overgebracht naar een ander leidingnetwerk. Het onttrokken water wordt vervolgens …

An estimated 17 million tonnes of tires are discarded annually. Re-use is achieved by retreading (9%), recycling (39%), energy recovery (37%) and landfill (5%). A preferred, but complex way of recycling is to make new tires from discarded tire rubber. Vulcanised car tire rubber has to be devulcanized …

Brandweerlieden worden aan grote hitte blootgesteld. In dit onderzoek is nagegaan of 2 koelsystemen onder het brandweerpak de warmtebelasting verminderden. Het ene systeem bestond uit absorptiemateriaal met water dat er uit verdampt en het andere is een hesje waardoor ijswater liep. Het laatste systeem …

Turbine blade cooling has been a topic of significant interest, as increasing turbine entry temperatures result in higher cooling requirements. The present numerical method divides the blade into a finite number of elements in the span and peripheral directions and solves the heat transfer fundamental …

Research is done on the properties of a niobium superconducting magnetic shield sample (see image below this abstract), its magnetic attenuation; and behaviour around the transition temperature 9.25 K. The attenuation of the magnetic shield sample was measured in a cryogenic setup. This is required to …

There are several greenhouses built with solar panels integrated into the roof. In summer time this will operate very well, although broad shadow stripes can result in growth and yield differences. In winter the amount of sunlight is further limited by the solar panels and will result in further reduction …

The objective of this concept is a significant reduction of energy consumption in greenhouses and buildings with large facades and windows by using available solar energy. The scope of this investigation is to study the advantages of a building integrated CPV system. The basic idea is that a larger fraction …
