Liquid Propulsion

Liquid Propulsion Modeling and Fluid Flow Design

The NASA standard tool for heat transfer and fluid flow analysis, SINDA/FLUINT, includes thermodynamic and hydrodynamic solutions specifically targeted at the growing demand for design and analysis of liquid propulsion systems.

Many organizations have previously used separate in-house tools specialized for each of the above applications. However, these organizations typically do not have the resources nor infrastructure to maintain these codes when cognizant engineers are lost, nor to modify and validate them for new vehicles or applications, nor to train new engineers on their use. The use of a single general-purpose tool to encompass all such analyses offers not only solutions to these problems, but also enables integrated analyses and the ability to communicate with vendors and customers.

An extensive set of generalized thermal/fluid modeling tools exists that was developed to satisfy the specialized needs of liquid propulsion system design and analysis. These tools can uniquely provide integrated modeling of an entire fuel tank system including pressurization system, feedline, and turbopump. They can also link intimately with thermal models of the structure and environment. Included are high-level design synthesis, statistical design, and model correlation modules. An extensive infrastructure exists of pre- and postprocessing software, training, and user support. While the models made using these tools might be proprietary, the tools themselves are readily available to all organizations, overcoming significant limitations of in-house codes.

Introduction to Two-phase Flow

September 24, 2-3pm MDT

This webinar introduces basic concepts in two-phase flow modeling including quality, void fraction, flow regimes, slip flow, pressure drops and accelerations, and heat transfer.

No knowledge of CRTech software is required. However, references to the corresponding FloCAD features will be made to assist users of that product.
