✦ Synopsis

II A method of evaluating local heat fluxes by heat conduction and visualizating local heat fluxes in a heated plate is described. In the first stage, the temperature distribution of a heated plate located in a parallel-plate duct was measured by a thermo-camera developed by the authors, using liquid crystals of high resolution (0.01 °C). In the next stage, the deviated heat flux, the difference between the local heat flux and a uniform heat flux in the plate, was evaluated by solving numerically the three-dimensional equation of heat conduction. As a result, the heat flux distribution was visualized locally.
