Numerical Analysis on The way of Tea Between Expert and Non-Expert

In this paper, the processes of Japanese ‘the way of tea’ making by expert and non-expert were investigated. The bubble form and distribution states after 100% and 50% of tea making finishing time were recorded and analyzed through numerical processing. In order to verify the relationship between the bubble distribution and the tea making motion, the whole tea making processes by expert and non-expert were record and compared by high-speed camera. Consequently, it can be concluded that expert can efficient way to make a perfect Japanese tea.
