[12-2016] Student Amit Koikkarah Aji wins Venlo Circular Challenge 2016

Amit Koikkarah Aji, (M.Sc Chemical Engineering Student) recently participated in a sustainable business challenge called "Venlo Circular Challenge 2016" conducted by Sustainable Motion NL from November 4th to December 16th. Twelve teams around the Netherlands were selected to participate in the challenge. The challenge has 3 business case studies from Royal Zon, Office Depot and Oce with each business case having 4 teams to work with. He was working on a remanufacturing business case by Oce along with 3 other members (Amarens (Masters Student, Venlo), Stefka (Masters Student, Tilburg) and Nila (Masters Student, Nijmegen) and they emerged victorious in the final held on 16th December. The jury member complimented the novelty of their solution and also the way his team tackled the overall challenge.

[11-2016] David Vermaas’ spin-off company AquaBattery wins Herman Wijffels Innovation Award

The spin-off company AquaBattery of TP’s faculty member David Vermaas was awarded with the Herman Wijffels Innovation Award on November 3rd, for the most sustainable innovation in the category ‘Circular economy’. AquaBattery develops stationary electricity storage using the osmotic power from mixing salt and fresh water. This enables to store excess of renewable electricity, by concentrating the salt water using ion exchange membranes and an electric field. When electricity is required at a later moment, electricity can be generated from the salinity gradient over the same ion exchange membranes. Hence, the energy is stored in mixing entropy, instead of reaction enthalpy in traditional batteries.

The jury praised AquaBattery’s product for its use of sustainable materials (water and salt), scalability and safety. The award includes a gift of € 20.000 to further develop this type of electricity storage. AquaBattery developed its product in collaboration with Wetsus and TU Delft, and will start a pilot test next year for electricity storage in households at The Green Village at the TU Delft campus.

[10-2016] MOOC "The Basics of Transport Phenomena" back online

The Massive Open Online Course (MOOC) "The Basics of Transport Phenomena" kick-started last year. A whopping number of students had enrolled for the course: 7570, consisting foremost of students from India and the USA. Good luck fitting that many students in a physical lecture room!

October 21st 2016 the course goes online for a second time on the EdX platform. How many students will enroll this year?

[04-2016] Dr. Rajat Bhardwaj's research featured in Delta magazine

Our former PhD student, now Doctor, Rajat Bhardwaj was interviewed by Delta magazine (Dutch only). His work was about a cheap sustainable way of providing drinking water to the poor: the solar still. Having been raised in India, he has witnessed the many issues of the lack of healthy drinking water for the poor. As an example, a bright eight-year old girl in a class he taught was forced to leave school to provide her family with fresh drinking water.

In the interview he talks about his motivations, experiences and ambitions.

[04-2016] Benhard Righolt's paper selected as editor's choice

The paper "Analytical solutions of one-way coupled magnetohydrodynamic free surface flow" by TP's PhD student Bernhard Righolt has been selected as editors' choice by the journal Applied Mathematical Modelling.

Editor Dr Petar Liovic says, "This paper presents analytical solutions to the problem of flow in a conducting liquid pool where recirculation is driven by imposed potential differences and transverse magnetic fields, in what is a well-defined 2D interfacial magnetohydrodynamic (MHD) flow. Comparison against Direct Numerical Simulation (DNS) enabled analytical model accuracy preservation with changing dimensionless parameters to be quantified. This paper should primarily serve the CFD community well as a benchmark problem for free surface MHD flow, enabling the coupled effects of MHD force modelling, surface tension modelling, jump conditions capturing, discretisation schemes and mesh resolution to be interrogated. Moreover, the paper features a useful demonstration of the utility of the moving mesh interface tracking method, and its recent implementation in OpenFOAM as the interTrackFoam module."

[02-2016] Prof. Mudde appointed as "Distinguished Professor"

Prof. R.F. Mudde has been appointed as "Distinguished Professor in Science Education" by the Board of TU Delft.

[11-2015] Shell Graduation Award for Kevin van As

PhD-student Kevin van As won a Shell Graduation Award (2014-2015) for his MSc thesis work. He studied MSc Applied Physics at TU Delft, and graduated on a joint project between our group, Transport Phenomena, and the Optics group, under the supervision of Dr. S. Kenjeres and Dr. N. Bhattacharya. The work was a novel project, in which he developed a computer code which is able to compute the light scattered by an ensemble of spheres. This may be used to study light scattering by red blood cells, with the ultimate goal of extracting cardiac parameters from the scattered light.

The award has been awarded on November 30th 2015 in the "Hodshon huis" of the KHMW. A news article has appeared in "AD Groene Hart" (01 Dec 2015), "Witte Weekblad" (02 Dec 2015), "TU Delft intranet", and "TU Delft Delta".

Research of our PhD student Michiel Musterd featured in Delta magazine

After publishing in Physical Review Letters on the roll-off behaviour of droplets, our PhD student Michiel Musterd has been interviewed by the Delta magazine. You can find the full interview on their website. (Dutch only).

Phys. Rev. Lett. on Local and Global Hysteresis now published

We proudly announce that our most recent work on pinning of droplets is now published in Physical Review Letters. The paper by Michiel Musterd, Volkert van Steijn, Chris Kleijn and Michiel Kreutzer is entitled "Droplets on inclined plates: Local and global hysteresis of pinned capillary surfaces" and deals with a theory that accounts for constrained contact line motion. Including this constrained motion in the model allows a description of previously unexplained phenomenon for droplets on inclined plates. The theory paves the road to a fully predictive model of droplet pinning by identifying the effect of the droplet width as the sole contributor to the history effects at roll-off.

Article by Kamali and Van den Akker featured on Advances in Engineering

The article entitled Simulating Gas–Liquid Flows by Means of a Pseudopotential Lattice Boltzmann Method was recently published in Industrial Engineering Chemistry Research and has now been recognized by the selection team of Advances in Engineering as a key advancement in the field.
