Available in PDF, EPUB and Kindle. Book excerpt: Temperature profiles were produced from 6 thermocouples that were placed on the external wall surface of the transfer line and insulated with Melamine foam insulation. Chilldown times were computed from temperature profiles and an approximate Leidenfrost temperature of -98°C was observed. Large circumferential temperature gradients were observed during chilldown and moderate axial gradients were also observed during the passing of the quenching front. The mass flux of the experiments had a considerable impact on the chilldown time and magnitude of the temperature gradients. The experimental facility and the current data will be used in continued research to develop a comprehensive and fundamentally based numerical chilldown model.

Available in PDF, EPUB and Kindle. Book excerpt: We consider problem of modeling and controlling two-phase cryogenic flows during ground loading operations. We introduce homogeneous moving front and separated two-phase flow solvers that are capable of fast and accurate online predictions of flow dynamics during chilldown and transfer under nominal conditions and in the presence of faults. Concise sets of cryogenic correlations are proposed in each case. We present results of application of proposed solvers to the analysis of chilldown in large-scale experimental cryogenic transfer line build in Kennedy Space Center. We discuss optimization of parameters of cryogenic models obtained using general inferential framework and an application of the solvers to the fault detection and evaluation based on D-matrix approach. It is shown that solver,Äôs predictions are in good agreement with experimental data obtained for liquid nitrogen flow in nominal regime and in the presence of faults.
Download or read book Critical Two Phase Flow for Cryogenic Fluids Classic Reprint written by Raymond Virgil Smith and published by Forgotten Books. This book was released on 2017-10-28 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Critical Two-Phase Flow for Cryogenic Fluids This work presents a state-of-the-art survey intended to be useful to a designer of equipment involving two - phase flow of cryogenic fluids. It is desirable to assess the probability of critical, or choking, flow in such a system and, if possible, estimate the critical flow rate. The literature is surveyed, primarily since Smith and the predictive results for several analytical models are evaluated and com pared with experimental data. These results are discussed; however, no firm conclusions are reached because, often, the spread of experimental data is equivalent to that of the predictive results from the models.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the technology of cryogenic comminution has been widely applied in the field of chemical engineering, food making, medicine production, and particularly in recycling of waste materials. Because of the increasing pollution of waste tires and the shortage of raw rubber resource, the recycling process for waste rubber products has become important and commercially viable. This technology has shown a great number of advantages such as causing no environmental pollution, requiring low energy consumption and producing high quality products. Hence, the normal crusher which was used to reclaim materials, such as waste tires, nylon, plastic and many polymer materials at atmospheric 12 temperature is being replaced by a cryogenic crusher. • In the cryogenic crusher, the property of the milled material is usually very sensitive to temperature change. When a crusher is in operation, it will generate a great deal of heat that causes the material temperature increased. Once the temperature increases over the vitrification temperature, the material property will change and lose the brittle behavior causing the energy consumption to rise sharply. Consequently, the comminution process cannot be continued. Therefore, it is believed that the cryogenic crusher is the most critical component in the cryogenic comminution system. The research on the temperature increase and energy consumption in the cryogenic crusher is not only to reduce the energy consumption of the crasher, but also to reduce the energy consumption of the cryogenic system.

Download or read book Two Phase Flow Boiling and Condensation written by S. Mostafa Ghiaasiaan and published by Cambridge University Press. This book was released on 2014-08-07 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text is an introduction to gas-liquid two-phase flow, boiling and condensation for graduate students, professionals, and researchers in mechanical, nuclear, and chemical engineering. The book provides a balanced coverage of two-phase flow and phase change fundamentals, well-established art and science dealing with conventional systems, and the rapidly developing areas of microchannel flow and heat transfer. It is based on the author's more than 15 years of teaching experience. Instructors teaching multiphase flow have had to rely on a multitude of books and reference materials. This book remedies that problem by covering all the topics that are essential for a graduate first course. Among the important areas that are discussed in the book, and are not adequately covered by virtually all the available textbooks, are: two-phase flow model conservation equations and their numerical solution; condensation with and without noncondensables; and two-phase flow, boiling, and condensation in mini and microchannels.
