Abstract
A fluid transfer arrangement comprising a duct having a first end and a second end, a pulse generation mechanism located at the first end of the duct to direct fluid pulses towards the second end of the duct in use, and a baffle located at the second end of the duct that defines an aperture having sharp edges. The sharp edges generate ring vortex fluid flow from the aperture in use. Applications include impingement heating and cooling.
Claims18
An impingement heating or cooling arrangement comprising:
- a duct having a first end and a second end,
- a pulse generation mechanism located at the first end of the duct to direct fluid pulses towards the second end of the duct in use, and
- a baffle located at the second end of the duct that defines an aperture having sharp edges,
- wherein the sharp edges generate ring vortex fluid flow from the aperture in use.
