O. Molerus,K.-E. Wirththe relationship between the state of knowledge and the valuation of outputs, have been studied in the framework of a total analysis in chapter 10. With this cause for ambivalence being extensively discussed, I now want to analyze one particular consequence of a situation in which goods and bads are强所 发表于 2025-3-27 09:15:36

Introduction,r long history. Heat transfer between bubbling fluidized beds and submerged surfaces is described by heat transfer coefficients related to the temperature difference between the heating surface and the bulk of the bed. There are different options to derive appropriate theoretical predictions, so relEuthyroid 发表于 2025-3-27 18:05:10
Particle migration at solid surfaces and heat transfer in bubbling fluidized beds,e. But due to the lack of appropriate measurement techniques in the past, modelling of particle migration to and from heat exchanger surfaces was based primarily on speculation and less on experimental evidence. This chapter therefore has two objectives.ACTIN 发表于 2025-3-28 00:23:37

Prediction of minimum fluidization velocity,ion velocity. Furthermore, as will be shown in Chapter 7, the correlation for the prediction of bubbling fluidized heat transfer will contain minimum fluidization velocity instead of particle size, i. e. minimum fluidization velocity is regarded as a key feature.happiness 发表于 2025-3-28 07:18:13

Heat transfer at Ar > 108,s .> 5 mm at elevated pressures of say 20 bar (2 MPa), even higher in the case of hot systems, owing to increased gas viscosity. These systems, however, reveal an interesting feature, which is different to those discussed in the preceding chapters. As visualized in Fig. 9.1, with increasing superfic
