In this article, we have described a computational framework for multiscale simulation of gas flow in subject-specific airway models of the human lung. The framework consists of five major components: accurate extraction of airway geometry from MDCT image data sets, geometrical modeling of airway trees, novel 3-D and 1-D coupled mesh generation, 3-D ...

The heart is modeled as a system of elastic and/or contractile fibers immersed in a viscous incompressible fluid. Simulated heart walls and valves are constructed by arranging the fibers according to an idealized version of the actual distribution of muscle fibers in the heart walls and collagen fibers in the valve leaflets. Then the combined motion of

Physiological Measurement, 2004
Hydrocephalus is far more complicated than a simple disorder of CSF circulation. Historically, it has been diagnosed using clinical and psychomotor assessment plus brain imaging. The role of physiological measurement to aid diagnosis becomes more appreciated in current clinical practice. This has been reflected by recently formulated guidelines for the

Placenta, 2007
Water arrives in the mammalian gestation from the maternal circulation across the placenta. It then circulates between the fetal water compartments, including the fetal body compartments, the placenta and the amniotic fluid. Amniotic fluid is created by the flow of fluid from the fetal lung and bladder.

The nearly inexhaustible variety of flow phenomena - from the flow through blood vessels, the flow in centrifugal pumps to global weather events is based on a few basic physical laws only. In this chapter these will be briefly reviewed and their general nature illuminated. Emphasis will be on the phenomena which are of special interest and significance
