A. Karagiozis et al., NATURAL-CONVECTION HEAT-TRANSFER FROM ARRAYS OF ISOTHERMAL TRIANGULARFINS IN AIR, Journal of heat transfer, 116(1), 1994, pp. 105-111
Measurements of the heat transfer to air by natural convection from ar
rays of isothermal triangular fins on a vertical base plate are report
ed for several array geometries, for a large range of Rayleigh number,
and for two orientations (vertical fins and horizontal fins). The dat
a are believed to be the first available for this important geometry.
A single equation is provided that correlates the measured Nusselt num
bers for the vertical orientation with an rms error of 4.8 percent. Th
e horizontal fin orientation was shown to have inferior heat transfer
performance.
