A Study on the Heat Transfer in Radial Fin of Rectangular Profile

사각형(四角形) 단면(斷面)을 가진 반경(半徑)핀에서의 열전달(熱傳達)에 관(關)한 연구(硏究)

In this paper, temperature distributions in radial fin of rectangular profile for steady-state with no heat generation are obtained by one-dimensional analytical method, finite difference method and experiment respectively. Heat flow rate and fin efficiency from the fin model are obtained by analytical method. Consequently, temperature distributions in radial fin can certify that are similar to exact solution. From theoretical analysis, the effects according to heat flow rate and fin efficiency are related to variation of parameters which are fin thickness ${\delta}_o$, fin base temperature $T_o$, thermal conductivity K with same basic dimensions and the effects are studied and compared.
