Abstract
The local heat transfer coefficients for isothermal and uniform heat flux boundary conditions for a two-dimensional wall jet have been experimentally determined. Hot wire anemometry surveys were used to quantify the velocity field in the wall jet. A micro thermocouple was used to quantify the temperature field in the wall jet for the isothermal boundary condition. Infrared imaging was applied to measure the wall temperature for the uniform heat flux boundary condition. The difference in the local convection coefficients due to the different thermal boundary conditions was largest at the leading edge of the heated wall and decreased in the stream wise direction. The local convection coefficient was found to be insensitive to the thermal boundary condition in the more turbulent region of the wall jet.
