Power & Flow

Power & Flow focuses on clean and efficient combustion and process technology, to cater for fast-growing energy demands.

Studying tomorrow’s fuels

Today, we need to shift towards ultra-clean, highly efficient ‘low-temperature’ combustion methods. We are also seeing increased use of biofuels, and eventually the emergence of fuels derived from sustainable sources, such as solar and metal fuels. Optimizing combustion and process devices, in combination with different fuel formulations to minimize undesired emissions and maximize thermal efficiency, is essential to supporting both of these developments.  

Combustion systems and their fuels

This theme is connected to the development of smart injection and combustion strategies of future ultra-clean and efficient combustion systems as well as with the after treatment, with a focus on future diesel engines. Our studies on fuels include: i) enhanced oil recovery, ii) use of bio-based fuels based on biomass components such as lignin, and iii) using micro-structuring gas-liquid bubbly flow processes to intensify biogas-to-liquid conversion.

Metal fuels as dense CO2-free energy carriers

This research is concerned with a novel type of fuels: metal powders that have a tremendously high energy density and can act as a major CO2-free energy carrier for the long term. Within the group we develop the combustion technology of metal powder, solid handling including separation and regeneration through chemical reduction with renewable hydrogen.

Complex multiphase flows

The research theme is related to various applications in the field of process technology, all involving complex multiphase flow phenomena. This includes equipment with phase transitions, such as evaporation of sessile multi-component ink droplets, cooling of steel by water jets and water-steam flow in evaporator tubes.

Student Opportunities

Are you a student interested in graduating or doing a project in the Power & Flow group? Our research covers a very broad range of subjects. We design, make and test systems for various power and flow applications. In most of our graduation projects we perform experimental, theoretical or numerical studies of the interplay between heat (production) and flow. Students use these studies to either understand the fundamentals of these heat and flow problems or to apply them and find practical solutions on how to operate or optimize the application.
