Research has been done to improve the understanding the self-heat effect, due to power dissipation, of temperature-dependant resistors in the VSL water calorimeter. A custom measurement program has been written to be able to control and read out three Agilent 3458A digital multimeters (DMMs). With these …

This report describes the work that has been done on the water calorimeter project at VSL. The calorimeter determines the absorbed-dose-to water Dw in gray, by measuring the radiation induced temperature change. The temperature of the water will change due to irradiation of a beam ionizing radiation. …

Kipp & Zonen, based in Delft manufactures and develops atmospheric measurement instruments, including a scintillometer. Kipp & Zonen currently manufactures the large aperture scintillometer (LAS) MkII and previously manufactured the extra large aperture scintillometer (XLAS) MkI. A scintillometer can …

Which parameters are the most important factors in the decision making process of heat networks?

In this research, the experiences and behaviors of end-users in a smart grid project are explored. In PowerMatching City, the leading Dutch smart grid project, 40 households were equipped with various decentralized energy sources (PV and microCHP), hybrid heat pumps, smart appliances, smart meters and …

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 …

Renewable energy is often suggested as a possible solution for reducing greenhouse gas emissions and decreasing dependency on fossil energy sources. The most readily available renewable energy sources in Europe, wind, solar and biomass are dispersed by nature, making them ideally suited for use within …

The European Union is striving for a high penetration of renewable energy production in the future energy grid. Currently, the EU energy directive is aiming for 20% renewable energy production in the year 2020. In future plans the EU strives for approximately 80% renewable energy production by the year …

Cancer is a worldwidehuman health problem.This is why much effortis put in finding solutions and treatments for this disease. One of the emerging adjuvant cancer treatments, hyperthermia, is applied by heating the tumourtissue, and is shown to increase the effects of radio and/ or chemotherapy. Because …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …
