Maths aids mayonnaise production

11.09.2008
How bubbles behave in liquids is important to many production processes, but also extremely difficult to calculate. TU Delft researcher Jok Tang, who received his PhD on Monday 8 September, is helping to change this.

The subject of ‘gas bubbles in liquids’ has many applications in industry. Examples include separating oil from water in the oil industry, how ink drops behave in printers and the manufacture of products in the food industry, such as mayonnaise. ‘This subject of course also applies to natural processes such as rainfall and boiling water,’ PhD student Jok Tang adds.

Experiments
Industry benefits from knowing how a current with bubbles behaves. This knowledge enables production processes to be improved. Until now, in spite of ever more powerful computers, it has proved difficult to calculate the behaviour of currents with bubbles properly. Computers required too much time to solve the corresponding mathematical equations.

To gain insight into current behaviour, scientists generally conduct small-scale experiments. ‘But,’ Tang says, ‘these experiments are expensive and difficult to perform.’
Quick
‘We believe that our method will be adopted by industry in the not too distant future. Not just because the need for this method becomes greater when calculating larger-scale problems, but mainly because it is quicker and cheaper than the methods used now,’ Tang explains.

Tang, who has been studying for his PhD in the research group headed by Prof. Kees Vuik, won two prizes with his research earlier this year: the Student Prize at the 9th International Symposium on Iterative Methods in Scientific Computing (IMACS) in Lille and the best poster prize at Burgers Day 2008 in Delft.

Im Focus: A Chip with Blood Vessels

Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.

Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...

Im Focus: A Leap Into Quantum Technology

Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.

In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...

What does it look like below the ice shelf of the calved massive iceberg A68?

On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.

Im Focus: Penn engineers develop ultrathin, ultralight 'nanocardboard'

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...

Im Focus: Coping with errors in the quantum age

Physicists at ETH Zurich demonstrate how errors that occur during the manipulation of quantum system can be monitored and corrected on the fly

The field of quantum computation has seen tremendous progress in recent years. Bit by bit, quantum devices start to challenge conventional computers, at least...
