Abstract |
|
An experimental investigation has been carried out to study the heat transfer coefficient by using artificial roughness in the form of specially prepared square shaped inclined roughness on the absorber plate of an air heater. The roughened surface is uniformly heated while the remaining three walls are insulated. These boundary conditions corresponds closely to those found in solar air heaters. The experiments having Reynolds number ranging from 3000 to 8000.the angle of attack of flow on roughness=150,300,450,600is used in the experiment. The heat transfer data obtained is compared with the data obtained from smooth duct under similar geometrical conditions. |
