In this study, a see-through Stirling engine was designed and constructed to encourage students to interest in engineering education. First, we used laminated acrylic plates and glass syringes to develop the simple see-through Stirling engine. Then, a simple temperature visualization technique was explored to stimulate students to interest and to support design changes that will improve engine performance. Thermochromic liquid crystal films were used to visualize temperature distributions around the cylinder, and drastic thermal changes around the cylinder were shown on the condition that operated an engine as a refrigerator. The result of a questionnaire to junior high school students, who attended the open campus exhibition, shows effectiveness to encourage their interest in engineering subjects.
In addition, this paper discusses a simple linear 3D flow interpolation method based on 2D-PIV (Particle Image Velocimetry) measurements that assist in understanding the driving mechanism.
