White Paper: Pressure Transients in Propulsion Tank Pressurization Lines

Posted on Oct 11, 2017 in News & Events, White Papers |

Published on: Oct 2, 2017 By: Valcor Aerospace Pressure Transients in Propulsion Tank Pressurization Lines Vitor Cardoso – Assistant Chief Engineer, Aerospace Products Richard Kelly – Senior Project Engineer, Aerospace Products Yuri Gerasimov – Chief Engineer, Aerospace Products Abstract Water hammer is a much studied and well known phenomenon. Water hammer is usually associated with pressure surges that can occur in propellant feedlines during engine startup and shutdown. These pressure surges can be the cause of structural damage if they exceed the proof pressure rating of the system. Although much has been done to study the effect of water hammer in propellant feedlines, often the effects of transients in the helium tank pressurization lines is overlooked1. This could be since pressure surges are not always associated with gases. Large solenoid valves have been replacing pneumatic regulators for propellant tank pressurization. These valves are used to create a “bang-bang” pressurization system. Multiple solenoid valves are connected in parallel to create a “bank”. All the same size valves are used in the bank, however they each have a different size flow control orifice installed in the outlet of the valve to provide different flow rates. Each valve is cycled open and closed, as determined by the control scheme, which is maintaining a fixed target pressure in the propellant tank, as the flow demand is changing during flight. These helium flowrates can be large enough to cause significant pressure spikes, as these solenoid valves are suddenly opened and closed. It is for this reason that it is prudent to investigate the pressure transients in the helium pressurization lines, and the analysis presented herein should always be performed on any newly designed aerospace propulsion system. Introduction Historically water hammer was first studied for systems with instantly closing or opening valves. The first person to describe this effect was the Russian scientist Joukowski, who is responsible for the formula for pressure rise, which bears his name. The theory of water hammer was further expanded by the works of Allievi and Gibson, who are both responsible for the calculating the pressure response due to linear stroking valves2. However most of these equations are written for incompressible flow and do not apply to compressible flow, especially sonic flow. To date, a large amount of work has been performed on the subject, and there are many commercially available water hammer software packages that will solve almost any problem1. The purpose of this paper is to show the importance of the need to combine the line dynamics model with the solenoid valve model, since the time history of the valve poppet directly controls the resulting pressure rise. In doing so, we will present a simplified approach to combining...

White Paper: Instrumentation Cryogenic Valves

Posted on Sep 7, 2017 in News & Events, Product News, White Papers |

Published on: Oct 16, 2017 By: Louis J. Arcuri, Director of Sales & Marketing, Valcor Scientific Instrumentation Cryogenic Valves — Their proper design and application Questions? Contact Us! Name * E-Mail * How can we help you? Cryogenic media enhance our daily lives in so many ways. Our most frequent encounter with the byproduct of cryogenic gas usage is in our food chain. Much of the frozen food we buy is flash-frozen in cryogenic freezers that use liquid CO2 (LCO2) and more commonly, liquid nitrogen (LN2). Vegetables, poultry, fish, and beef are all flash-frozen in immersion cryogenic freezers. Commercially baked goods are cooled much more quickly, and ready for packaging using LN2 vapor. Frozen ice cream novelty treats are flash-frozen in an LN2 bath. Beverages like beer, soda, and sparkling drinks are often carbonated with LCO2 from bulk storage systems. Cryogenics are popular because they’re effective, relatively inexpensive, and don’t affect the color, taste, or flavor of the foods and beverages with which they come in contact. With the advent of microbulk systems, cryogenic cooling is available to more food and beverage processors than ever before, especially small customers who could otherwise not afford the large bulk tanks often seen outside of large-scale producers. Environmental test chambers use solenoid valves to control the flow of LN2, enabling testing at temperatures to -320° F. Environmental chambers are used for testing all manner of components, devices, and systems. They can simulate the cold of deep space; or arctic ambient conditions. Combinations of cryogenic gases are used for a type of surgery known as cryosurgery. LN2 is directly applied to many skin maladies for freezing and removal such as warts, moles, and skin tags. Liquid Argon (LAR) is often used to create a freezing point at the tip of a probe. LAR treatments include freezing of tumors and cancerous tissue. Cryoablation prevents arterial fibrillation in cardiac patients. Cryofreezing minimizes damage to the surrounding healthy tissue. LCO2 is frequently used for cleaning and deburring. CO2 snow cleans surfaces quickly and efficiently, leaving no residue behind. CO2 cleaning is frequently used in optics manufacturing, painted surface preparation, and some semiconductor devices. Dry Ice, or frozen CO2, is used as an abrasive to deburr parts that are too delicate for traditional glass beading or sand blasting techniques. CO2 is also a great solvent; it is often used in a supercritical state to extract the essential oils that are associated with flavors and fragrances. It is also used to decaffeinate coffee and tea, and in sometimes to dry clean fabrics! Finally, we all enjoy the special effects created by LCO2 fogging machines! Whether at a rock concert, or on a Broadway stage, the low-hanging CO2 fog...
