Definition of Visualization

This article explores the concept of visualization, particularly in the context of temperature analysis and emission visualization. Guided by Prof. Kuniyuki Kitagawa and Dr. Nelfa Desmira, we discuss how to make invisible phenomena visible, such as thermal emissions from candles. Using technology like CCD cameras and heat image analysis, we can visualize temperature variations and emissions from different oils, illustrating their fatty acid contents. This study emphasizes the significance of visualization techniques in scientific inquiry and everyday understanding.

  2. What is Visualization Visualization  to make something visible Can you see the sun light? Or perhaps radiation or emission? It is visible actually, but we could not see it with our naked eyes.

  3. Thermal visualization of candles We can determine the flame temperature of candles using thermometer, but we can not visualize it. Japanese Candle The colors show the temperature range. Red is about 1800 – 2000 ºC While green is about 1500 ºC. Note. Japanese candles made in Japan use the raw materials such as pine tar and wax tree nuts. Candles made in Kerosene Candle

  4. How we did that? Temperature Video Camera 2D imaging of flame temperature by using heat image analysis system

  5. (a) (b) (c) (d) (e) Emission Visualization ofvegetable oils The emission generated from vegetable oils are different, due to the their fatty acids content. We cant see it with naked eye, but it exist. We can visualize it clearly using CCD camera. Results of NO emission images in the flame of various SVOs (a)Corn oil, (b) Jatropha Oil, (c) Palm Oil, (d) Sunflower oil, (e) Soybean Oil

  6. ICCD How we did that? Image intensifier CCD Camera

  7. How to visualize something ? Visualization Science

  8. Assignment • Describe a thing that you want to visualize and if it possible, can you make the way to visualize it?
