One phase of a fundamental investigation of convection over point and line sources of heat, conducted through the past decade at the Iowa Institute of Hydraulic Research, simulated a method of fog dispersal used for the landing of aircraft in England during the war. This involved the release of heat from parallel lines of burners, the convection from which produced characteristic patterns of mean flow and of heat intensity above the burners. Experiments described in this paper consisted of the measurement of the velocity distribution and the temperature distribution at various model scales and rates of heat generation. The results have been reduced to dimensionless diagrams of the two distribution functions which satisfy the elementary continuity and impulsemomentum requirements. From these diagrams generalized families of stream lines and isotherms for the mean motion above the sources have been plotted. The general functions reveal the basic pattern of convection and permit the approximate evaluation of velocity and temperature rise for any desired combination of the independent variables.
