Natural convection heat transfer is of a great interest in a lot of industrial applications: nuclear technologies, electronic circuit board cooling and many other fields. Only few studies have been carried out to determine the effect of surface roughness or shape on natural convective laminar flow. In this paper the effect of periodic patterns of protrusions (ribs) on the freeconvection heat transfer in a vertical plate, with uniform heat flux rate boundary condition, is experimentally investigated. The convective fluid is air. Heat transfer measurements are performed by using the infrared thermography and the heated thin foil technique
