WebJan 1, 2005 · The diaphragm is the principal muscle of inspiration. 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. WebOn entry-flow effects in bifurcating, blocked or constricted tubes Smith, F. T. The paper is concerned mainly with the various effects of practically uniform entry conditions on the flow through an indented or branching tube on the assumptions of an incompressible fluid, steady and laminar flow, and a large characteristic Reynolds number.

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.
