Figure 4.
(a) Instantaneous fluid velocity within the lacunar-canalicular porosity and strain over time for a node at the surface of a central vascular pore, from a model with vascular canal diameter of 15 μm and lacunar-canalicular permeabilites of 10−20,10−21 and 10−22 m2; the outputs for 10−19 and 10−18 m2 are not shown because they are almost identical to the 10−20 m2 output. Negative strain represents compression in the axial top-down direction. Positive fluid velocity represents fluid flowing towards the vascular pore surface. (b) Average fluid velocity magnitude within the lacunar-canalicular system from idealized models with different vascular pore diameters (15, 20, 25 and 30 μm) and lacunar-canalicular permeabilities (10−18 to 10−22 m2).
