At first, we made up an appropriate configuration of design and determined which factors might have effect on slim products. Then we determined control factors and standards of control factors that were set according to the standard of Dr. Taguchi's experimental orthogonal array. With the bigger the better of orthogonal array, L9(3^4), we conducted confirmation procedure on operating factors by use of cypress essential oil on slim cosmetics. The experiment was used to obtain best combination of parameters by S/N ratio and characterizations that were based on the data constructed by Taguchi Methods.

Moreover, as the heat flux approach to CHF, numerous vapor mushrooms periodically extruded from the perimeter of fin array are observed. This mechanism will cause the dry-out situation in the central part of fin array. The closer fin spacing and longer fin length can provide larger heat transfer. However, the results also demonstrate that early decay on overall heat transfer coefficient as the fin spacing is closer or fin length is longer.
