The Effect of a Uniform Cross-flow on the Circulation of Vortex Rings (2007)

Hassan, E. R., Kelso, R. M., Lanspeary, P. V., Jacobs, Peter, McIntyre, Tim, Cleary, Matthew, ...

This paper describes observations and measurements of the effects of a uniform cross flow on the vorticity field and circulation of a laminar vortex ring ejected from an elevated pipe. From...

Engineering formula for pressure loss in an oscillating-triangular-jet nozzle (2007)

Lanspeary, P. V., Lee, S. K., Jacobs, Peter, McIntyre, Tim, Cleary, Matthew, Buttsworth, David, ...

A nozzle consisting of a circular inlet orice and a short chamber with an exit lip can produce a naturally oscillating jet ow if the expansion ratio from inlet to chamber (D/d1) is larger than ve. As...

Strouhal Number of Naturally-Oscillating Triangular and Circular Jets (2007)

Lee, S. K., Lanspeary, P. V., Nathan, G. J., Jacobs, Peter, McIntyre, Tim, Cleary, Matthew, ...

A nozzle consisting of an abrupt expansion into a short openended tube can produce a naturally-excited oscillating-jet flow. The characteristics of the oscillating jet depend on jet-orifice to...

On Flow Structure in an Oscillating-Triangular-Jet Nozzle: Conditionally-Averaged Wall Pressure (2007)

Lee, S. K., Lanspeary, P. V., Jacobs, Peter, McIntyre, Tim, Cleary, Matthew, Buttsworth, David, ...

A jet flow from a triangular-inlet orifice can be made to oscillate or “precess” by partially confining it with a short cylindrical chamber. However, for a narrow range of chamber lengths, the...

Surface-flow patterns in oscillating-triangular-jet nozzles (2004)

Lee, S. K., Lanspeary, P. V., Nathan, Graham Jerrold, Kelso, Richard Malcolm

A triangular-jet nozzle which usually produces an oscillating-jet flow can, for a narrow range of geometric parameters, produce a stationary deflected jet which reattaches to the internal surface of...
