ws to a product is pure fiction. This is due to the fundamental epistemological conditions of LCA as a modelling process under the complexity of our socio-economic system. Instead, various mental models and values guide this attribution. This leads to a functional model in a specific decision situat

Convective Heat Transfer to Low-Temperature Fluidse on forced convection because more applications for that type of cooling are found. In most instances turbulent forced convection will be discussed. Low-temperature fluids can exist as gases, two-phase fluids, low-temperature liquids, or near-critical-state liquids. These fluid states are depicted

Critical Heat Fluxduction in heat transfer results from the transition, which may be rather sudden and which is accompanied by a substantial rise in surface temperature. Knowledge of the critical heat flux dictates whether a system is designed with a nucleate boiling heat transfer coefficient (Chapter 5), representin

Film Boilingtermediate vapor film The vapor film forms a continuous, relatively regular blanket over the solid surface. This liquid-over-vapor arrangement is inherently unstable. However, the solid—liquid temperature differences characteristic of film boiling are so large that no liquid can remain in contact wi

Minimum Film Boiling Heat Fluxs used to predict the magnitude of this heat flux are based on hydrodynamic instability theories (see Refs. l–3 for good descriptions of the mathematical model). Agreement of the theory with experiment has been good. However, because of the fact that the phenomenon occurs as a result of an instabili
