Natural convective flows around a pair of vertical heated plates were investigated both analytically and experimentally. Main concerns are directed to an interaction of thermal plumes arising from the plates and also to its influence on the local heat transfer from the plates. In order to simulate the flow and temperature fields around the plates, full elliptic equations for the momentum and energy transport were solved numerically for the computational domain that encloses the plates. The results showed that the present elliptic analysis well predicts the plume interaction and also the local heat transfer coefficients of the plates. The present results were also compared with those of the conventional parabolic analysis. The results depict that a full elliptic analysis is necessary to obtain accurate local quantities such as the velocity distributions in between the plates and also the local heat transfer coefficients of the plates.
