Description
This paper illustrates the use on an infrared image processor as a new temperature measurement and display method of the heat flow formed by an extended flame from an opening using a reduced model. In order to visualize the temperature distribution of the hot air, a stainless steel net and a ceramic sheet were set in the path or the heat flow as subject for the infrared image processor during separate experiments. The visualized temperatures were compared with the corresponding temperatures obtained by using chromelalumel thermocouples. Temperatures obtained by the infrared image processor were lower than the ones indicated by the thermocouples. The upper part of the thermal trajectory line (i.e. maximum temperature line along the flow) obtained by the visualized temperatures was located further from the vertical wall than the ones indicated by the thermocouples and Yokoi's data. This newly developed method gave a clear and wide enough temperature contour map for the experimental study of the flame extention.
