Free convective heat transfer across inclined air layers
- Univ. of Waterloo, Ont.
This paper presents new experimental measurements on free convective heat transfer rates through inclined air layers of high aspect ratio, heated from below. The Rayleigh number range covered is from subcritical to 10/sup 5/; the range of the angle of inclination, phi measured from the horizontal is: 0 less than phi less than approximately 70 deg. Although it was anticipated that the results might be identical to the results for the horizontal layer if one replaced Ra by Ra cos phi, significant departures from this behavior were observed, particularly in the range 1708 less than Ra cos phi less than 10/sup 4/, 30 deg less than or equal to phi less than 60 deg. A recommended relationship giving the Nusselt number as a function of Ra cos phi and phi is reported. This relationship fits all data closely.
