Constructal dendritic configuration for the radiation heating of a solid stream

Bejan, Adrian (AMER INST PHYSICS, 2010)

Here we show that the configuration of a slender enclosure can be optimized such that the radiation heating of a stream of solid is performed with minimal fuel consumption at the global level. The solid moves longitudinally ...
Natural constructal emergence of vascular design with turbulent flow

Cetkin, E.; Bejan, Adrian (AMER INST PHYSICS, 2010)

Here, we show that vascular design emerges naturally when a volume is bathed by a single stream in turbulent flow. The stream enters the volume, spreads itself to bathe the volume, and then reconstitutes itself as a single ...
Vascular structures for volumetric cooling and mechanical strength

Bejan, Adrian (AMER INST PHYSICS, 2010)

When solid material is removed in order to create flow channels in a load carrying structure, the strength of the structure decreases. On the other hand, a structure with channels is lighter and easier to transport as part ...
