To ensure safety and reliability, it is important that the explosives and other materials used in munitions do not interact adversely either physically or chemically. Data obtained by heat flow calorimetry on nitrocellulose-based propellants have been reviewed with the aim of identifying improved chemical compatibility assessment criteria. It...

In this paper we show the results from indoor and outdoor measurements on solar cells and modules, manufactured with different bifacial and monofacial cell architectures and encapsulated in different configurations. Reflection/transmission, IV and IQE spectra of single-cell laminates were measured and used to determine the energy spectra for all...

Frisse lucht zorgt voor een goede en diepere slaap. Dus bieden veel kinderdagverblijven de mogelijkheid om kleintjes buiten te laten slapen. Kan dat onder alle weersomstandigheden? En waar let je op als het bijvoorbeeld pijpenstelen regent of vriest dat het kraakt?

Pressure pulsations are an intrinsic feature of reciprocating compressor systems, that may lead to various issues. The API 618 standard is the most relevant guideline for pulsation and vibration control during the design stage. However, the main focus of API 618 is on pulsation effects in the field piping, and less on the pulsations close to the...

Onze buitenlucht is schoner dan de lucht in woningen. Deze treurige constatering werd onlangs gedaan tijdens de 'Dag van de Binnenlucht', die werd georganiseerd door onder andere de VLA en Isso. Klopt het wel? We belden TNO-onderzoeker Piet Jacobs op om hem hierover aan de tand te voelen.

In this paper we present results of a global resource assessment for geothermal energy within deep aquifers for direct heat utilization. Greenhouse heating, spatial heating, and spatial cooling are considered in this assessment. We derive subsurface temperatures from geophysical data and apply a volumetric heat-in-place method to improve current...

For a large new refinery project in the Middle East, the design and construction of a very large hydrogen compression unit was required. The compression unit design resulted in the requirement for six large reciprocating compressors operating in parallel, with a total installed electrical power close to 100 MW. The compressors have common...

A 140 l lab scale shell-and-tube PCM heat storage was built and tested, and the experimental results were compared to a numerical model. Natural convection in the PCM was found to significantly influence the local temperature distribution in the storage vessel, which could not be predicted well by the model, since the model assumes only...

Membrane distillation is an attractive technology for production of fresh water from seawater. The MemPower® concept, studied in this work, uses available heat (86 °C) to produce pressurized water (2.2 bar and 46 °C) by membrane distillation, which again can be used to power a turbine for co-production of electricity. We develop a non...

Recirculation hoods equipped with carbon and plasma filters are becoming more and more popular. The aim of this study is to determine the effectiveness of recirculation hoods with regard to PM2 5 and NOx removal in a 26 m3 lab kitchen with a gas furnace. With the carbon filter PM2 5 is reduced for about 30%. A fresh carbon filter removed about...

Het innovatieprogramma Energiesprong is eind 2016 beëindigd en opgevolgd door de Stroomversnelling, een initiatief van bouwers en woningcorporaties om Nom-renovaties op gang te brengen. Met het afronden van de Energiesprong is de tijd gekomen om in de volle breedte de stand op te maken van wat we vanuit de woningmonitoring hebben geleerd van de...

The AIVC Technical note 68 "Residential Ventilation and Health" summarises studies that prioritise pollutants in the indoor environment and presents a summary of pollutants driving the indoor health risks and their sources. It also describes methods to reduce exposures of contaminants using different control strategies with a special emphasis on...

In performance prediction of IR sensor systems for missile detection, apart from the sensor specifications, target signatures are essential variables. Very often, for velocities up to Mach 2-2.5, a simple model based on the aerodynamic heating of a perfect gas was used to calculate the temperatures of missile targets. This typically results in...

Fijnstof met een deeltjesgrootte tot en met 2,5 µm (PM2,5) veroorzaakt met afstand de grootste gezondheidslast in vergelijking met andere binnenmilieufactoren. TNO toont aan dat pieken aan fijnstofconcentratie rond het koken in huis verantwoordelijk zijn voor circa 30% van de totale blootstelling aan fijnstof, inclusief de blootstelling die in...

The spatial distribution of Particulate Matter has been studied during class time in a naturally ventilated classroom. Measurements were taken between the pupils at breathing height, and at the side and front between 0,15 and 4 m height. With regard to PM1, PM2,5 and PM10, hardly any differences were observed in concentration, between the...

In the frame of the OFFICAIR project, office buildings were investigated across Europe to assess how the office workers are exposed to different particulate matter (PM) characteristics (i.e. PM2.5 mass concentration, particulate oxidative potential (OP) based on ascorbate and reduced glutathione depletion, trace element concentration and total...

In dit artikel wordt specifiek ingegaan op de Nederlandse regelgeving voor kachels en open haarden en tevens een vergelijking gemaakt met de buitenlandse regelgeving. Nederland blijkt in Europa nogal achter te lopen wat betreft regelgeving voor fijnstofemissie vanuit houtstook. In 2022 wordt Europese regelgeving van kracht, die helaas niet gaat...
