A series of fire wind tunnel experiments using one or two propane gas burners was conducted for elucidating real-scale fire plume properties for burning houses with strong wind. Plume temperature distributions, etc. were measured for various heat release rates and approaching wind velocities. Non-dimensional number introduced for plume temperature at each measurement point was assembled according to Froude number and other non-dimensional numbers. The approximation equation is consistent with the one in past studies by the author using a small-scale wind tunnel facility. It is expectecl that an estimation equation predicting temperature distributions transformed from the above approximation equation is generally applied for plume temperature from one or two burning houses with wind. Moreover, basic experiments using a small-scale wind tunnel facility were conducted for heat sources of various rectangular shapes for applying the estimation equation to a heat source of any shape.
