“…Heat transfer due to natural convection from vertical and horizontal fin arrays are investigated by several researchers, for instance, Starner and McManus [4], Welling and Wooldridge [5], Harahap and McManus [6], Jones and Smith [7], Karki and Patankar [8]. Recent experimental studies by Rao and Venkateshan [9], and Yüncü and Anbar [10] on vertical fin with horizontal base consider simultaneous free convection and radiation. Additional experimental evidence on natural convection from shrouded vertical fin with vertical base can be seen in Fisher and Torrance [11], in which chimney effect was discussed.…”
