Abstract

The influence of forced vibration on the free convection heat transfer from a sinusoidal surface has been experimentally investigated in this paper. A copper plate of [350×150×10 mm] length, width and thickness respectively has been used as a test sample where, the upper surface of this plate is manufactured by a wire-cutting machine as a sinusoidal surface with 0.3 amplitude to wavelength ratio. This plate is heated by electric heater under constant heat flux conditions ranging as [250, 500, 750, 1000, 1250 and 1500 W/m2] and subjected to vertical forced vibration with frequencies [5, 10, 15, 20 and 25 Hz] and [3, 4 and 5 mm] peak to peak vibration amplitude, the Rayleigh number (Ra) ranging from [1.5×108 to 4.0×108], the vibrational Reynolds number (
