Dr Christoph Buchner (FOTEC Forschungs- und Technologietransfer GmbH)06/10/2020, 11:30thermal technologies and methodologies related to small satellites and CubeSats
Recently FOTEC started the development of 3D-printed heat pipes as a prospective thermal management solution for a high-power CubeSat thruster. The use of 3D printing could improve design flexibility and adaptability in geometrically confined situations, while enabling the heat pipe to be manufactured in one process, minimizing the number of thermal interfaces.

Dr Ramon van den Berg (Senior Engineer)06/10/2020, 12:00thermal technologies and methodologies related to small satellites and CubeSats
With the miniaturization of space-borne sensors, more powerful payloads are anticipated to be used in small satellites. Therefore, new thermal concepts are required to cope with the increasing thermal dissipation and the negative effects. This paper presents a new thermal control concept to thermally standardize small satellites with power dissipation problems and making them thermally...

Ms Aleksandra Onufrena (CERN/UTwente/ESA)06/10/2020, 14:00thermal design (for platforms, instruments etc.)
Compact efficient Counter Flow Heat EXchangers (CFHEX) or recuperators are crucial components of recuperative coolers, such as Joule-Thomson and Turbo-Brayton coolers. Also in cryogenic systems that apply a convective cooling loop, in which a working fluid is circulated by a warm pump and cooled by a cryocooler, high-effectiveness recuperators are essential. In a collaboration project of ESA,...

To prevent thermal induced breakdown, thermal modelling is a crucial task during each design phase of a new space mission. Monte Carlo ray tracing, while computationally demanding, is usually the go-to method to simulate thermal energy transfer. State of the art thermal modelling suites, such as ESATAN-TMS, usually rely on a CPU-based implementation of Monte Carlo ray tracing.
