Hoe kun jij met kattenbakvulling je huis verwarmen?

Dit college is niet voor de poes. In de toekomst stoken we onze huizen namelijk warm met een zonnecollector op het dak en een flinke bak kattengrind in de kelder. Hoe dat kan? Dat vertelt David Smeulders (TU Eindhoven) in dit college voor de Universiteit van Nederland.

Cum laude voor modelleren van ‘fracken’

TU/e-onderzoeker Ernst Remij ontwikkelde nieuwe rekenmodellen om het winnen van olie en gas door middel van ‘fracken’ nauwkeuriger te bestuderen. Hij promoveerde cum laude op zijn onderzoek aan de faculteit Werktuigbouwkunde, onder begeleiding van David Smeulders, Joris Remmers en Jacques Huyghe.

De Warmetruiendag app!

Boris Kingma, onderzoeker thermoregulatie en fysieke activiteit Universiteit van Maastricht en energietechnologie Technische Universiteit Eindhoven, ontwikkelde in 2013 de zogenaamde CLO app. Speciaal voor Warmetruiendag werd de app aangepast en aangevuld met een aantal vragen.

Is het warm of koud buiten? Wat draagt de rest van Nederland?  Welke kleding past het best bij het weer? De app Warmtetruiendag (Clo) geeft je precies die informatie! Tegelijkertijd kun je meedoen aan onderzoek door te delen wat je aanhebt en hoe je de temperatuur ervaart. (Download hem hier: https://play.google.com/store/apps/details?id=com.kingma.warmetruiendag, voor Android, de Apple versie volgt zo snel mogelijk).

Food waste could store solar and wind energy

Saving up excess solar and wind energy for times when the sun is down or the air is still requires a storage device. Batteries get the most attention as a promising solution although pumped hydroelectric storage is currently used most often. Now TU/e researchers  Huaichen Zhang, Silvia Nedea, Camilo Rindt and David Smeulders reporting in ACS’ Journal of Physical Chemistry C are advancing another potential approach using sugar alcohols — an abundant waste product of the food industry — mixed with carbon nanotubes.

Thermochemical heat storage one step closer

In 2014 about 60% of all residential energy consumption in the Netherlands was used for space heating and hot tap water. This part of the energy consumption can be completely covered by solar energy if seasonal heat storage systems are employed in Dutch households. In a seasonal heat storage system, solar thermal energy stored in summer is used to provide heat in winter. Shuiquan Lan, PhD student in the research group Energy Technology, aims at gaining insight into the fundamental processes involved in thermochemical heat storage using salt hydrates in order to bring thermochemical heat storage in Dutch households one step closer.

Can salt hydrates be used for domestic seasonal heat storage?

With the renewable energy challenge of our generation, seasonal heat storage in the residential sector has emerged as an important research topic, with the aim of developing a sustainable concept that can entirely fulfill the heat demand over a year of individual dwellings. The PhD thesis of Claire Ferchaud focuses on micro-scale testing of several salt hydrate materials in order to get a better insight in its properties and to test whether or not these salt hydrates materials could be used in the domestic application of seasonal heat storage.

Results PhD research on water properties to be included in global standard

Knowledge on droplet formation is of great importance to science and industry. Since the late 19th century, when Charles Wilson was among the first to study this phenomenon, scientists try to contribute to the knowledge on condensation. One of them is PhD student Maurice Fransen, research group Energy Technology, with his experimental research on homogeneous water nucleation. The results will be incorporated into the global standard on the properties of water and steam.

Solar Jet in TU/e contest

"The future of solar aerospace within our reach"

In a student project we are designing a high-speed model aircraft powered by solar energy. The first concept is a small R/C model to explore the possibilities in propulsion, structure design and energy storage. Our current model uses hydrogen as energy carrier. This hydrogen is sustainable produced with solar power. The engine is a combination of an impulse turbine and a ramjet, to fly at almost transonic speeds.

In September 2015 a new student team will be founded, so other students can join this project.

PhD explained: humidity harvesting

Water scarcity is a global challenge of our generation, which motivates researchers to find new sources of drinking water. PhD student Daniel Bergmair, Energy Technology, focused his research on the design of a system for humidity harvesting. His work could be a crucial step to make humidity harvesting an attractive source of freshwater in the future.

Middenin de actuele energievraagstukken

We hebben geen energieprobleem, we hebben een opslagprobleem. Aan het woord is David Smeulders, hoogleraar Energy Technology. Er is dus dringend behoefte aan nieuwe manieren om energie tijdelijk te parkeren voor later gebruik. Met zijn groep zoekt hij naar nieuwe materialen met dit doel. Daarnaast rekent hij aan een ander actueel onderwerp binnen het energievraagstuk: moeilijk bereikbare gas- en olievoorraden, zoals schaliegas.

De vonk van David Smeulders

Sympathiek, geëngageerd en jongensachtig; het zijn zo maar wat beschrijvingen die David
Smeulders (1961) typeren. Ambitieus van kinds af aan. Niet zozeer vanuit een ‘moeten’, maar
vanuit een drang dingen te willen weten, begrijpen. Het vakgebied waarin hij terecht is gekomen - energietechnologie - raakt steeds meer in een stroomversnelling en energie staat wereldwijd hoog op de agenda.

TU/e’ers werken aan sensor voor nierdialyse op maat

Als je nierfunctie niet of nauwelijks meer werkt, is de kans groot dat je als nierpatiënt bent aangewezen op uren durende dialysebehandelingen in speciale centra of ziekenhuizen. De groep Energie Technologie van de faculteit Werkbouwkunde is bezig met de ontwikkeling van een optische sensor die de huidige dialysebehandelingen meer op maat kan maken. Hiermee kan de kans op complicaties tijdens de dialyse verkleind worden.

Darcy Lab

How is damage to concrete caused in a fire? What exactly happens when concrete ‘rots’? And how can we make a lossless ‘thermal battery’ so you no longer need to use gas or electricity to heat your home? Questions like these are central at the TU/e Darcy Lab, which officially opened in February 2014. To get the answers, the researchers will use advanced hospital equipment to investigate how water and the salts dissolved in it are transported in porous materials.
