WebDec 1, 2024 · Flow path curvature is responsible for the development of Dean-type secondary motion while flow division at the bifurcation ridge generates secondary motion opposite to that induced by curvature. An increase of flow area from inlet to outlet results in an increase of asymmetry in cross-sectional velocity distribution. WebWinters K (2006) A bifurcation study of laminar flow in a curved tube of rectangular cross-section, Journal of Fluid Mechanics, 10.1017/S0022112087001848, 180:-1, (343), Online …

The steady axisymmetric flow first experiences a small region of time-dependent non-axisymmetric instability, before undergoing a regular bifurcation to a steady non-axisymmetric state with azimuthal … WebOrthogonal collocation and continuation techniques are used to study the bifurcation structure in symmetric flows. The problem of flow in an infinite curved slit which bifurcates to give rise to a cellular structure is considered. The addition of 'stickiness' at the cell boundaries is shown to turn each pair of cells into a curved duct of rectangular cross …

Contraction of the diaphragm leads to enlargement of the Airflow in the Respiratory System 33 The volume of air inspired in a normal breath, termed tidal volume (TV or VT), is about 0.45-0.60 L for a healthy adult at rest. During heavy work, the tidal volume may exceed 1.5 L.
