Heat transfer experiment on natural convection in a square cavity with discrete sources

The present research investigates the effects of the dimensions and the positions of heating sources in the lateral walls of a square cavity. The temperature distributions in the air and the heat transfer coefficients are measured experimentally by holographic interferometry and compared with the numerical results obtained with Fluent 12.1.4. Experimentally and numerically, it is observed how the sizes and the positions of the heat sources influence the velocity field
