Experimental investigations were carried out on the characteristics of the thermal field of a wall plume arising from a horizontal line heat source embedded on the low part of a vertical wall surface. For the stability analysis of the present wall plume field, a vibrating copper wire was set horizontally near the line heat source in the field. The wall plume field was disturbed by the wire, and some two-dimensional sinusoidal thermal disturbances were introduced into the wall plume field. The growth or diminution of the thermal amplitude of disturbance was measured in the wall plume field with a thermal probe. The frequency response of the disturbance in the wall plume field was also examined. As a result, it was ascertained that the frequency response of the wall plume field was fit well with the prediction of the linear stability analysis.
