Finned Space Radiator Performance Analysis Using Computational Methods

“…According to their study, the increased mass, which will elevate the costs, is compensated by the electrical energy saving. This energy saving is of great importance to projects of this kind, once it is a limited resource [6,7]. In the work by Lieblein and Diedrich, the authors conducted an analysis on materials and geometries used in the construction of space radiators in order to evaluate the relation between mass, ease of manufacture and heat transfer rate provided by the device.…”

“…In the work by Lieblein and Diedrich, the authors conducted an analysis on materials and geometries used in the construction of space radiators in order to evaluate the relation between mass, ease of manufacture and heat transfer rate provided by the device. They have concluded that the requirements outlined above are usually in conflict [7]. Garcia presented a one-dimensional numerical model that analyses the multimode heat transfer in a radiator with rectangular fins as shown in Fig.…”
