A Study on the Optimal Arrangement of Heating and Cooling Tubes for Uniform Temperature Distribution of Heat Transfer Surface

전열면 온도의 균일분포를 위한 냉각 및 가열관의 최적 배열에 관한 연구

The temperature distributions inside molds with heating or cooling tubes were calculated using special boundary element method. This special boundary element method was employed in order to reduce the error for small diameter tubes. Calculated temperature was compared with results using finite element method. It was found that the current method becomes more accurate as tubes' diameter gets smaller. Optimal arrangement of tubes for uniform temperature distribution along specific surface was found. CONMIN program was employed for the optimization.
