This book was released on 2022-08-04 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal screens are commonly used as components for fluid handling in spacecraft and rocket tank designs. In most cases, the screens perform a passive separation of the propellant phases. The separation of the liquid from the gaseous propellant phase, is a special challenge. Liquid-gas phase separation means that the gaseous phase is allowed to enter a phase separation device while the liquid phase is blocked. The technical application of this process is the depressurization in a propellant tank. A certain amount of the gaseous propellant phase is vented from the tank through the gas port. The liquid propellant phase remains in the tank in order to be stored for the engine. However, if the tank causes a liquid movement during the depressurization, a part of the liquid can potentially enter the gas port. In order to prevent the unwanted liquid outflow, a separation of the liquid from the gas is necessary. This is possible with the aid of a double screen element and has already been performed for storable liquids in Earth’s gravity and microgravity as well as for cryogenic liquids in Earth’s gravity. At the current state of the art, the separation of the liquid from the gaseous phase of the cryogenic propellant hydrogen using a double screen element has not been performed in microgravity. However, with regard to a possible application, it is mandatory to investigate the function of the double screen element for the real propellant under relevant environmental conditions. In this work, a cryogenic test facility has been developed and operated successfully under Earth’s gravity and microgravity conditions using the drop tower at the University of Bremen. Hereby, the original, cryogenic propellant phases: liquid and gaseous hydrogen, have been used. The experiments show the appearance of the physical processes which are related to the retention capability of a double screen element against liquid hydrogen. Furthermore, these physical processes can obviously be influenced by an unknown boundary condition at the screens: the screen saturation. This unknown boundary condition in turn can obviously be influenced by a certain stimulus which causes a special, fluid mechanical process. A simplified mathematical and two numerical models have been developed which combine the observed, physical processes in the experiments. Two fitting parameters are introduced which influence the flow through screen pressure loss of the liquid and the gaseous hydrogen phase. After the fitting to experimental data, the two fitting parameters have been interpreted with respect to a possible screen saturation. The results lead to a prediction of the unknown boundary condition and indicate that a partial saturation of the screens with liquid could be present in each considered experiment. This can possibly lead to a major influence of the overall resistance of the double screen element against liquid hydrogen.

Available in PDF, EPUB and Kindle. Book excerpt: Bibliographic Guide to Refrigeration 1965-1968 is a bibliographic guide to all the documents abstracted in the International Institute of Refrigeration Bulletin during the period 1965-1968. The references include nearly 7,000 reports, articles, and communications, classified according to subjects, and followed by a listing of books. This book is divided into 10 parts and begins with a listing of references on thermodynamics, heat transfer, and other basic physical phenomena relating to refrigeration, including desiccation and measurements of temperature, humidity, and pressure. The next sections are devoted to the physics of low temperatures and cryogenics; production and distribution of cold; refrigerating plants (mainly in the food domain); and refrigerated transport and packaging. Other references deal with air conditioning and heat pumps; and industrial, biological, medical, and agricultural applications of refrigeration. The final section focuses on standards and regulations, economics and statistics, and education and trade activities in the refrigeration industry. This guide is intended to assist researchers, engineers, manufacturers, and operators who are in either constant or occasional contact with the refrigeration domain.
