Gas liquid level and location determination

Og Gas/Fluid Inventory Determination

Og Gas/Fluid Inventory Determination

  • Accurate inventory determination is challenging due to a few factors:

    • Substance orientation

    • Substance properties

    • Measurement technique

  • Several RFPs have been granted to develop new technologies to provide better accuracy in 1g and 0g conditions


What s the goal

What’s The Goal?

  • Develop a non-intrusive, reliable, simple instrument to accurately determine the inventory level

    • Use ‘dumb’ sensors

    • Utilize simple physics

    • Take advantage of ‘random’ nature of fluid


Compressed sensing

Compressed Sensing

  • Process of acquiring and reconstructing a signal that is supposed to be sparse or compressible.

  • An undetermined system has more unknowns than equations and generally has an infinite number of solutions.

    • However, if there is a unique sparse solution to the underdetermined system, then the Compressed Sensing framework allows the recovery of that solution.

    • Not all underdetermined systems of linear equations have a sparse solution.


Procedure

Procedure

  • Develop MCNP model to stochastically track particles/photons through system and record counts at detector locations

  • Develop a library of known fill levels and detector responses

  • Query library with new detector responses to determine fill level utilizing compressed sensing approaches


More complex system

More Complex System

  • An interest in determining fill level and location of liquid in tank in zero gravity

  • Utilize similar approach to earth-g system but allow liquid to be located anywhere in the tank.

  • Solve for both fill and location

Summary

Summary

  • A new approach to inventory fill determination has been demonstrated utilizing a unique, simple, non-intrusive detector arrangement

  • Approach may potentially be capable of accurately determining zero-g liquid inventory and liquid location


Classroom application

Classroom Application

  • Pre-AP Algebra II

  • Linear programming

    • Students will be expected to formulate systems of equations and inequalities from this particular situation, use a variety of methods to solve, and then analyze the solution in terms of the situation.
