Modified local similarity for natural convection along a nonisothermal vertical flat plate including stratification
An approximate method has been developed to analyze natural convection along a vertical flat plate with variable surface conditions and temperature stratification. This method uses the boundary layer velocity and temperature profiles from the local similarity method and imposes explicit conversion of energy along the plate resulting in required relationships for the similarity parameters for energy conservation. The results from this Modified Local Similarity (MLS) method are compared to those from other methods for a number of nonsimilar natural convection problems. Based on these comparisons, the MLS method is a significant improvement to the local similarity approach and is a useful approximate tool for analyzing natural convection on vertical surfaces for nonsimilar conditions. 22 refs., 11 figs.
