3.0 Cryogenic Tankage

This post is a continuation of previous video clips from the short course on cryogenic fluid management (CFM) I taught at NASA's Thermal and Fluid Analysis Workshop in September, 2022. The reference report used to present the course topics can be accessed on the Training page at www.moraninnovation.com.

Matt Moran is the Managing Member at Moran Innovation LLC, and previous Managing Partner at Isotherm Energy. He's been developing power and propulsion systems for more than 40 years; and first-of-a-kind liquid, slush and gaseous hydrogen systems since the mid-1980s. Matt was also the Sector Manager for Energy & Materials in his last position at NASA where he worked for 31 years. He's been a cofounder in seven technology based start-ups; and provided R&D and engineering support to hundreds of organizations. Matt has three patents and more than 50 publications including the Cryogenic Fluid Management report series. More about him can be found here.

2.0 Environments for Cryogenic Fluid Management

This post is a continuation of previous posts of video clips from the short course on cryogenic fluid management (CFM) I taught at NASA's Thermal and Fluid Analysis Workshop in September, 2022. The reference report used to present the course topics can be accessed on the Training page at www.moraninnovation.com.

Although this section on environments is tailored for the aerospace audience of the NASA short course, the approach can be applied to other applications with appropriate modifications. For example, stationary liquid hydrogen energy storage would need to address local transient solar flux (including day/night cycles), temperature, weather, and seasonal fluctuations (all in normal gravity). Likewise, mobile applications would have thermal and acceleration environments based on the the vehicle (e.g., aircraft, marine, train, truck, etc.) and associated operations.

Calculations for Introduction to Cryogenic Fluid Management

My previous post provided introductory video clips from the short course on cryogenic fluid management (CFM) I taught at NASA's Thermal and Fluid Analysis Workshop in September, 2022. The reference report used to present the course topics can be accessed on the Training page at www.moraninnovation.com.

The final section in the Introduction chapter contains example calculations to demonstrate how to use the tools and equations presented in the previous sections. As an additional resource, I've created a Jupyter notebook containing Python code with the key calculations and example exercises. It is available under a permissive open source license in my public GitHub repository at: https://github.com/moranmatthewe/CryoFM

I've attempted to include sufficient descriptive information and graphics to make the notebook useful as a standalone tool. The Python coding is intentionally straightforward to facilitate interpretation and make it easy to translate to other coding languages of interest to the user (e.g., VBA, C/C++, Matlab, Fortran, etc.).

If you have Python and JupyterLab on your computer, the Introduction notebook and CryoFM™ functions library can be downloaded and used locally (subject to the Apache 2.0 license). If you don't have these applications loaded but would like to try them out, I suggest using the Anaconda distribution to set up your computer with these and other useful programming tools.

Alternatively, if you prefer not to load these programs onto your local machine (or are prohibited by your IT department from doing so), an interactive web browser instance can be invoked using Binder that requires no downloads nor software installation. To try this method, simply look at the readme file on my GitHub repository and click on the "launch binder" icon (see screenshot below).

1.0 Introduction to Cryogenic Fluid Management (CFM)

In September of 2022 I taught a short course on cryogenic fluid management (CFM) at NASA's Thermal and Fluid Analysis Workshop. The course covered analysis and design of liquid hydrogen systems as well as other cryogenic fluids used in power and propulsion applications.

Although the target audience was aerospace engineers and scientists, most of the topics are directly applicable to liquid hydrogen systems in general (e.g., energy, transportation, marine, etc.). As such, the course content can be used as a resource for the development of any liquid hydrogen system.

This first video is a short introduction. Subsequent videos posted over the coming weeks will cover the other topics presented during the course. My hope is that these edited clips will be easier to digest - and later revisit as needed - rather than posting the full ~3 hour video.

The reference report used to present the course topics can be accessed on the Training page at www.moraninnovation.com. Any feedback on this material, or future topics of interest, are appreciated and can be emailed to: info@moraninnovation.com.

The example calculations for these topics are discussed in the next post.
