Available in PDF, EPUB and Kindle. Book excerpt: The new-generation liquid oxygen/hydrocarbon propellant liquid fuel rocket engine will use a high-pressure combustion chamber arrangement. In this case, cooling the thrust chamber becomes a key technical problem. The article presents a design scheme for the geometric-dimension optimization of annular-type regenerative cooling channels. The aim of the optimization is minimum pressure losses as coolant passes through the cooling channel. As shown in typical computations and experiments, application of this optimizing design method can reduce 50% of pressure losses. In other words, the optimization design is advantageous in solving the cooling problem in high-pressure thrust chambers. jg.

Available in PDF, EPUB and Kindle. Book excerpt: Many parameters can have an effect of the cooling ability and pressure drop performance in high aspect ratio cooling channels (HARCC) However few studies have attempted to quantify these effects In the present study Fluent was used to solve the three-dimensional fluid dynamics and conjugate heat transfer within cooling channels of a variety of aspect ratios. The objective of these studies was to explore the potential impact of the asymmetric heating in a HARCC and to identify parameters which can have a significant effect upon the performance of High Aspect Ratio Cooling channels in order to design an experimental facility which will allow for the validation of the flow phenomenology.

This book was released on 2008 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: Convective heat transfer is important for maintaining life and reliability of the main combustion chamber in liquid rocket engines. Enhancing the regenerative cooling circuit's ability to maintain wall temperature with minimal pressure losses improves engine life and has the potential to reduce the turbopump output pressure. High aspect ratio coolant channels have been shown to reduce wall temperature with little pressure increase. Additionally, rocket engine cooling circuits are curved and the mechanisms responsible for curvature enhancement remain unclear for tall, narrow passages and appropriate predictive tools have not been developed. The objective of this research is to study the mechanisms responsible for improved cooling performance and to develop heat transfer correlations for use in high aspect ratio coolant channels having conducting side walls and subjected to asymmetric heating on the concave side, thus modeling a channel in a slotted liner. Tests are conducted with water in a single, curved channel subjected to heat flux on the outer radius wall and in a straight channel with heat input to an analogous wall.
