โœฆ Synopsis

An optimization model is described for lung and vascular tree structures. The model extends Murray's model, which is derived from minimal power dissipation due to the frictional resistance of laminar flow and the volume of the duct system. Instead of just laminar flow, it takes into account all types of steady flow, e.g. turbulent and laminar flow, and predicts which structural changes will occur among different parts of trees having different types of flow. The sensitivity of the optimal values is indicated and the model predictions are compared with literature data.

Arterial tree models are generated by Constrained Constructive Optimization according to minimum intravascular volume. These models, which have been shown to adequately reproduce pressure profiles and branching angles, are analysed topologically and geometrically in order to investigate how structur

A bifurcating tree-like network consists of a single inlet channel, which bifurcates over several levels to uniformly distributed microchannels that are vertically connected to a second network for fluid return. Here we introduce a one-dimensional model that considers convective heat transfer from

## Abstract Because of the severe increase of mortality by cardiovascular diseases, there has been rising interest among the tissueโ€engineering community for smallโ€sized blood vessel substitutes. Here we present small diameter vascular grafts made of slow degradable poly(ฮตโ€caprolactone) nanofibers
