Cryogenic Tank Analysis Program (CTAP)

Project Summary

Full Title: Cryogenic Tank Analysis Program (CTAP)
Project ID: 165
Principal Investigator: Rolf Baumgartner
Brief Description: CTAP predicts the thermodynamic state of a tank fluid based on quasi steady-state solutions of the first law of thermodynamics for a closed, isothermal system.

Purpose

Calculate boiloff rates and pressure rise in cryogenic storage and supply tanks.

Project Description

Type of Project: Model
Category: Hydrogen Fuel Pathways
Technologies Modeled: The system model consists of a pressure vessel, insulation, tank supports, fill, vent, and outflow lines. It has provisions for liquid and gas flow into or out of the tank, pressurization via heaters or helium pressurant, liquid or vapor expulsion, and a thermodynamic vent system option.
User Inputs: The user can select from twelve different operating scenarios and has available a wide variety of options for tank size, geometry, materials of construction, pressure-vessel supports, and insulation models.
Hardware/Software Requirements: Fortran
Outputs: Thermodynamic state of a tank fluid
Notes/Comments: CTAP was developed under a NASA SBIR Phase I program around 1999.
