The heat transfer from surfaces may in general be enhanced by increasing the heat transfer coefficient between a surface and its surroundings, and by increasing the heat transfer area of the surface, or by both. In most cases the heat transfer is concerned with the application of artificial surface roughness techniques as a turbulence promoter for convective heat transfer enhancement. To measure the transient and local convective heat transfer coefficient of an artificial roughened duct using liquid crystal thermography (LCT) technique, an experimental setup have been designed and developed. The aspect ratio of duct was maintained as three with relative roughness height ratio (e/D) of 0.13 and angle of attack is 900 for the range of Reynolds number from 7000 to 17500.
