Heat Transfer to Liquid Hydrocarbons under Supercritical Bubble Boiling Conditions | Chapter 10 | Current Research Progress in Physical Science Vol. 7

The study of heat transfer from heated surfaces to hydrocarbon mixtures has gained critical importance not only for energetic applications but also for its potential in medical therapies. Of particular interest are transient processes in hydrocarbon boiling, including regimes under supercritical bubble boiling (SBB) conditions. The unpredictable nature of these boiling modes makes it challenging to determine the heat transfer coefficients using conventional methods. This chapter presents data on heat transfer from a heated surface to hydrocarbon mixtures under convective, bubble, film, and supercritical bubble boiling regimes. The heat transfer process involves complex physicochemical phenomena, with hydrocarbon mixtures consisting of compounds with varying boiling points. During the heating of the surface, some low-boiling hydrocarbons evaporate, complicating the establishment of steady-state heat transfer. Furthermore, the presence of self oscillations during heat transfer complicates the process.

Performance of the Corresponding States Model of Dual-Reference on the Determination of Viscosity According to the Pressure of Hydrocarbon Mixtures in the Modeling Domain | Chapter 7 | New Ideas Concerning Science and Technology Vol. 10

 The model of K.A. Petersen [1] was used to predict viscosimetric activity in this study. The main idea behind this approach is to determine a fluid's viscosity using two models as a guide when going through a reduced pressure. The process is a two-reference corresponding state. This study demonstrates that the approach is based on the reference chosen, as well as any of the possible C10/C6H6 and C1/C10 references. For four different weight ratios, the findings were examined. It shows that adding a modified coefficient has no noticeable impact on the results when compared to the results without the adjustment factor, which appears to be the best option. In terms of the effect of the references chosen, the two couples tend to be a good match in general, but we should point out that this is not a prerequisite. The results are right in the case of mixtures containing at least one aromatic, particularly when comparing the ratio of adjustment and our ratio without adjustment to that of K. A. PETERSEN. The viscosity experimental findings are in good agreement with the measured values. We can predict that the implementation of the second body of reference (C10) from the model states corresponding to the authors' reference (C1) would result in a relative change.
