A study was conducted to determine the enhancement in convection heat transfer that could be achieved using the corona wind over a range of stream velocities. A heated flat plate mounted in a flow channel was placed in a Mach-Zehnder interferometer. Corona wires were placed above the active plate surface. Data were taken over a range of stream velocities. The results showed the expected large increase in heat transfer at low velocities and that this gain in heat transfer decreased to zero at high stream velocities.
