Cryogenics and Advanced Fluid Flow Design

Dewars, Cryostats, and Tank Pressurization

The general thermodynamic and hydrodynamic solutions used within CRTech's tool suite are capable of meeting the growing demand for cryogenic fluid system design. Many organizations have previously used in-house tools specialized for such 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 thermal/fluid modeling 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 exist within SINDA/FLUINT, Thermal Desktop®, and FloCAD® that satisfy the specialized needs of cryogenic fluid system design and analysis. These tools uniquely provide integrated modeling of an entire cryogenic tank system including pressurization, vaporization, and liquefication. They can also link intimately with thermal models of the structure and environment. Access is provided to SINDA/FLUINT's high-level design synthesis, statistical design, and model correlation modules in addition to the geometric and nongeometric user interfaces, training, and user support.

Cryogenic design applications include:

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.

Introductory FloCAD Training

Class times: September 5, 10, and 12, 2019, 9:00 am to 12:00 pm MDT daily
Cost: no charge (attendees must have an active support contract)

CRTech will be hosting introductory training for FloCAD (Flow Modeling in Thermal Desktop). This is our standard FloCAD class previously hosted in a classroom environment and now restructured for an online teaching environment.

The class will introduce single-phase fluid modeling concepts and how to build fluid models within the FloCAD work environment. Topics covered include an introduction to fluid modeling components, geometric versus non-geometric modeling options, working with FloCAD Pipes, solution control, and an introduction to path and pipe libraries.

The class will be broken into three two- to three-hour sessions held over a 3 day period. The format will be online lecture and demonstration with opportunities to ask questions. Hands-on lab work will be provided to students to work on after each session. To gain the most from this class, students are encouraged to attend all three sessions.

Prerequisites: Attendees must have basic working knowledge of Thermal Desktop as many of its base features will not be covered in this class but their usage is required for FloCAD.

Eligibility Requirement: This class is a service to our customers. All attendees must have an active support contract. If you are unsure of your support status, please contact CRTech.
