In this paper, the vertical diffusion was measured from line source injector under neutral boundary condition over rib-roughened wall in a water channel. The variation in gap distance between the rib-roughened wall characterized skimming flow (ribs c

Flow regimes were investigated in the cavity formed between the roughness elements in a laboratory water flume. Further tests were carried out on similar aspect ratio of the cavity to study the effect on turbulence production because of change in loc

Abdominal aortic aneurysms (AAAs) are abnormal aortic dilatations that are prone to rupture, with fatal consequences. Synthetic aneurysm models are being used to assess in vivo stress characteristics of aneurysms before and after surgical reinforceme

Objectives. To ascertain the effect of aneurysm thrombus and luminal diameter on arterial blood pressure within the abdominal aortic aneurysm lumen and at the sac wall. Methods. A life-like abdominal aortic aneurysm was incorporated in a pulsatile fl

Purpose: To construct life-like non-axisymmetrical abdominal aortic aneurysm models from latex. Technique: A computed tomographic 3-dimensional reconstruction of an actual abdominal aortic aneurysm was cast in plastic to provide a core for a “chemi

The initial entrainment characteristics of fine bed sand are objectively defined in terms of the measured distributions of critical instantaneous bed shear stress associated with the observed movement of individual surface grains. Critical flow condi
