A fluid transfer arrangement (34) comprising a duct (36) having a first end (38) and a second end, a pulse generation mechanism located at the first end (38) of the duct (36) to direct fluid pulses towards the second end (40) of the duct (36) in use, and a baffle (42) located at the second (40) end of the duct (36) that defines an aperture (44) having sharp edges (46). The sharp edges (46) generate ring vortex fluid flow from the aperture (44) in use. Applications include impingement heating and cooling. |
