Natural convective heat transfer along vertical plates with discontinuous heating elements has been studied by numerical computation and experiments. It has been found that the heat transfer on the surface of a plate and the temperature distribution of unheated elements change depending upon the ratio of the thermal conductivity of convective fluid and that of the unheated element material, the ratio of thickness and length of unheated elements, and the length and surface temperature of the heating elements. The heat transfer data are also found to be correlated by using a parameter S=B・・R_λ/G^<1/4>_<rL>, presented in this paper through vectorial dimensional analysis, and the observation of convective behavior visualized by a Mach-Zehnder interferometer and computational results. An empirical formula has been presented to predict heat transfer coefficients of discontinuously heated plates based on the new parameter S.
