A longitudinal study of Type-B aortic dissection and endovascular repair scenarios: Computational analyses
2013, Medical Engineering and PhysicsCitation Excerpt :A second order accurate discretization (central differences) was used to solve the flow velocity. Algebraic MultiGrid acceleration [18] was employed and the SIMPLEC-type pressure correction [19] was used for pressure–velocity coupling. Thoracic endovascular aortic repair (TEVAR) aims at sealing the tears along the intimal flap and, by reduction of FL perfusion and pressure, to induce FL thrombosis [20].
Ciliary behaviour and mechano-transduction in the embryonic node: Computational testing of hypotheses
2011, Medical Engineering and PhysicsCitation Excerpt :Our previous research regarding the regional flow produced by one active cilium suggested a vortical flow pattern with the velocity of 1.5 μm/s [41]; the current study, focusing on the overall nodal flow generated by an array of cilia, shows a much more rapid and unidirectional fluid transport in the embryonic node which is in excellent agreement with experimental reports (110 μm/s) [19], given measurement uncertainties. Most of the in vivo experimental research concerning the measurement of nodal flow has been done by placing fluorescent beads into the fluid bathing the node [46,58]. The results from these studies, however, are highly dependent on the position of the beads when being imported to the node cavity; the beads that are placed close to the cells might be trapped by the cilia during their travelling to the left, while those placed near the top of embryonic node may not be fully within the leftwards laminar flow.
