is founded in 1986 as an independent research company performing  theoretical and experimental work on thermoacoustic energy conversion. In this  field Aster has gained an outstanding experimental and theoretical knowledge position which makes Aster a leading partner in thermoacoustics.

Mission is to develop and commercialize thermoacoustic energy conversion in general with the focus on applications utilizing medium and low operating temperature heat driven thermoacoustic engines and heat pumps  for industrial as well as for rural applications like

• Thermo acoustic power (conversion of waste heat into electricity)
• Add-on to existing CHP using the engine’s exhaust gas
• Waste heat driven cooling
• Solar heat driven cooling
• Gas liquefaction
• Electricity generation from stove or wood fire
• and more..

Characteristic for thermoacoustic systems is the lack of moving parts in the thermodynamic process which simplifies the construction  and eliminate the need for maintenance. These features enables new waste and solar heat related applications not feasible today with conventional technology for technical or economic reasons. Physics behind however is quite complicated as it combines thermodynamics, acoustics, aerodynamics, heat transfer, engineering etc. For this work Aster has developed a dedicated set of measurement tools and simulation code.In its own workshop Aster has the tools and resources to construct  and test prototypes both for internal projects  as well as for research under order.

Aster could support projects and customers with a full range of activities including

• Conceptual design
• Simulations
• Experiments
• Measurements
• Test and prototyping.

 

Since a long time Aster collaborate with national and international research institutes and universities and is involved in many thermoacoustic related projects of which some are mentioned on the project page.
