| Outline of Final Research Achievements |
A novel measurement technique called a “fluid temperature-field scanner” has been developed. This technique enables us to visualize the spatial temperature distribution of a non-isothermal fluid flow by tracking the trajectory of a rod-like probe equipped with many temperature sensors by using a high-speed CCD camera. The key technique is an adaptive response-compensation scheme by which the response lag of the temperature sensors can be adequately compensated to reconstruct the temperature profile accurately.
Furthermore, a new measurement technique to visualize the spatial “velocity” distribution of an inhomogeneous flow field has been proposed. In the same manner as the fluid temperature-field scanner, a two-dimensional velocity profile can be visualized quantitatively. The rod-type probe consists of ten hot-wires operated by the constant-temperature anemometers. It is demonstrated that an inhomogeneous velocity field of an air jet flow can be visualized readily and accurately.
