Modeling convection

To model convection drying both the heat transfer to the coated web and the mass transfer (qv) from the coatiag must be considered. The heat-transfer coefficient can be taken as proportional to the 0.78 power of the air velocity or to the 0.39 power of the pressure difference between the air in the plenum and the ambient pressure at the coatiag. The improvement in heat-transfer coefficients in dryers since the 1900s is shown in Figure 20. The mass-transfer coefficient for solvent to the air stream is proportional to the heat-transfer coefficient and is related to it by the Clulton-Colbum analogy... [Pg.315]

If you used only tap water in your model, convection currents would bring warmer, less dense water from the bottom to the surface. Do you think this will happen with your solar pond model Explain your answer. [Pg.105]

While the work of Lin et al. is interesting in that it tries to model convective turbulence from first principles, it still contains arbitrary parameters (four) and approximations that cast doubts on the reliability of the results. Specifically, the height of the nebula H had to be chosen arbitrarily since the model as constructed by Lin et al. gives rise to a degenerate set of solutions for H. The arbitrariness in the choice of H... [Pg.61]
