摘要: Natural convection in an air layer contained a rectangular cavity having side walls of different temperatures has been investigated experimentally for various aspect ratios ranging from 4.9 to 78.7. Measured temperature profiles are analyzed with the flow regimes. Two Nusselt-Grashof correlations presented measured heat-transfer data, fitting data average deviation less than 7.8%. The Grashof number based on thickness ranged 1.5 × 103 7.0 106.
