An experimental investigation has been made of secondary flow in a 90 degree corner. The tests were run in a water tunnel at low speed (approximately 0.3 ft. per sec.) with emphasis on an attempt to visualize the embedded vortices in the laminar flow. The Reynolds number range was 11,000 to 52,500 per foot; the corner model was 9.75 in. wide by 48 in. long. The model was aligned in the tunnel so that no streamwise pressure gradient was present. Flow visualization was by means of hydrogen bubbles and dye. None of the streak-line examined with either the bubbles or the dye showed any indication of the presence of secondary motion in the first 18 inches of the corner. This is not believed to be conclusive since the vortices may exist at other distances along the corner (the limit here was imposed by the flow visualization apparatus used) or may be poorly developed in the initial length examined.

Download A Visualization Study of Secondary Flows in Cascades Book in PDF, ePub and Kindle
Flow-visualization techniques are employed to ascertain the streamline patterns of the nonpotential, secondary flows in the boundary layers of cascades, thereby providing a basis for more extended analyses in turbomachines. The three-dimensional deflection of the end-wall boundary layer results in the formation of a vortex well up in each cascade passage. The size and tightness of the vortex generated depend upon the main flow turning in the cascade passage. Once formed, a vortex resists turning in subsequent blade rows. This results in unfavorable angles of attack and possible flow disturbances on the pressure surfaces of subsequent blade rows when the vortices impinge on these surfaces.

Download Flow Phenomena in Nature: Inspiration, learning and application Book in PDF, ePub and Kindle
Do we have an adequate understanding of fluid dynamics phenomena in nature and evolution, and what physical models do we need? What can we learn from nature to stimulate innovations in thinking as well as in engineering applications? Concentrating on flight and propulsion, this unique and accessible book compares fluid dynamics solutions in nature with those in engineering. The respected international contributors present up-to-date research in an easy to understand manner, giving common viewpoints from fields such as zoology, engineering, biology, fluid mechanics and physics. This transdisciplinary approach eliminates barriers and opens wider perspectives to both of the challenging questions above. Contents: Applications in Engineering and Medicine; Inspiration from Nature; Steady and Unsteady Fluid Dynamics; Specific Numerical and Experimental Methods
