Assessment Criterion for Heat Transfer Deterioration of Supercritical Fluids [PDF]
Proceedings of the 3rd International Conference on Material, Mechanical and Manufacturing Engineering, 2015 In order to enlarge the application scope of the existing criteria for the heat transfer deterioration, the criteria of heat transfer deterioration was assessed by using the method of mechanism analysis and experimental data available in the literature. The obtained results indicated that the criteria based on q = f (G, D) are more useful for practical
