MATRIX형 세라믹 열교환기 코아의 열전단 및 열응력해석
박용환,우창수,Park, Yong-Hwan,U, Chang-Su 한국기계연구원 1994 硏究論文集 Vol.24 No.-
The heat transfer and thermal stress analysis was performed on the ceramic core of the matrix-type recuperator. The efficiency was calculated as 34% to 65%. Triple-pass arrangement provided higher preheated air temperatures, lower thermal stresses and the increase of pressure drops. Higher temperature gradients and maximum peak stresses appeared on the corners of the ceramic core. The effect of boundary conditions was significant and the use of spring-load sealing mechanism could release thermal stresses.
