Processes have been developed to integrate CIGS solar foils directly in plastic or composite based products. Using injection moulding and vacuum forming it turned out that mechanical stress is applied to the solar foil upon cooling. Using intermediate stress relief layers such as polyolefin this could …

Electrohydrodynamic atomization (EHDA) is a technique which uses the influence of strong electric fields to manipulate the break-up of a liquid, pumped through a capillary nozzle, into droplets. In this work, an extended description of a specific high flow EHDA mode, known as the simple-jet mode, is …

Total organic carbon (TOC) is often found in natural water sources, and also may come from (chemical) water treatment processes or from sewage. It may react with disinfectants to produce DBPs (disinfection by-products), which are harmful to water systems and public health. Besides, in industrial systems …

Cruise ship fires are not uncommon. Fire on board of the cruise ships is one of the most dangerous accident that can occur at any moment. The damage caused by fire is huge and can negatively affect the company’s reputation. There is a product on the market that can, according to the manufacturers, detect …

Introduction This report presents a conducted customer satisfaction research commissioned by Holiday Inn Leiden. The contractor wanted to know whether if the expectations of the Leisure-guests relate well on the final experiences. Holiday Inn Leiden was interested to conduct a research among the group …

Background Elevated temperature and air pollution have been associated with increased mortality. Exposure to heat and air pollution, as well as the density of vulnerable groups varies within cities. The objective was to investigate the extent of neighbourhood differences in mortality risk due to heat …

Stormwater flooding and thermal stresses of citizens are two important phenomena for most of the dense urban area. Due to the climate change, these two phenomena will occur more frequently and cause serious problems. Therefore, the sectors for public health and disaster management should be able to assess …

With increasing world population, more wastewater is produced which all need purification treatment. Removal of pathogenic organisms is important because they can cause problems to human health. This experiment will focus on the removal of human bacterial pathogens. The problem of human bacterial pathogens …

This report presents the experimental and numerical work carried out by ECN and Hanze University of Applied Sciences on methane sorption on activated carbon, as part of their activities within the EDGaR Energy Storage project. Eleven different activated carbon types were tested. It was found that MaxSorb …

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 …
