Experimental and numerical studies have both depicted the distribution of mass flow around an array of rectangular blocks due to buoyancy driven flows. The geometric configuration (array of rectangular blocks in-line arranged) simulates the cross-section of a disc-type transformer. It is a two-dimensional model. Transversal flows through horizontal channels (space between blocks) have been observed on an experimental set-up. Laser Doppler velocimeter is used to measure the velocity field. Numerical simulations of the flow in the same configuration have proved the influence of buoyancy forces, the pitch ratio and the asymmetric heating on the distribution of mass flow rate around the blocks.
