Abstract

In this paper, the unsteady incompressible Navier-Stokes equation coupled with energy equation was solved in order to investigate the thermal stimulation of continuous moxibustion using a commercial code (ANSYS-Fluent). In the simulations, various periods were selected for the continuous moxibustion, which was done by burning multiple disks successively. It has been found that the depth of the effective stimulation zone increases only when the replacing temperature is equal or larger than body temperature whereas the increase rate of the effective stimulation depth decreases as the number of disc increases. Further, it has been shown that the optimal period, for which the duration time of the effective stimulation zone is maximum, exists.

본 연구에서는 연속 뜸의 열자극 특성을 분석하기 위하여 복합대류 열전달 간이 모형을 만들어 ANSYS-FLUENT 를 이용하여 수치해석을 수행하였다. 연속 뜸의 주기가 열자극 효과에 미치는 영향을 파악하기 위해서 여러 장의 뜸을 다양한 주기로 적용하였다. 수치해석을 통하여 뜸의 장수가 증가할수록 유효자극영역의 깊이가 증가하기 위해서는 교체온도가 체온과 같거나 체온보다 커야 함을 확인하였고, 뜸의 적용 수가 증가함에 따른 유효자극 영역 깊이의 증가율은 감소함을 보였다. 또한, 유효자극의 지속시간이 최대가 되는 연속 뜸의 최적의 교체 주기가 존재함을 확인하였다.
