| Research Abstract |
A novel measurement technique for visualizing the spatial temperature distribution of a non-isothermal gas flow has been developed. By tracking the movement path of a specifically-developed multi-sensor temperature probe using a commercially-available high-speed CCD camera, we can measure quantitatively a two-dimensional temperature profile and project it to the measurement object image obtained by the CCD camera. The key technique is an adaptive response-compensation scheme based on a "two-thermocouple probe technique," by which the response lag of the temperature sensors can be adequately compensated; hence the temperature profile can be reconstructed accurately. As an example, we have demonstrated that the temperature field of the hot-air jet ejected from a hair dryer can be visualized readily and quantitatively. The results show the effectiveness and usefulness of the proposed visualization technique.
