Og Gas/Fluid Inventory Determination
Og Gas/Fluid Inventory Determination
Accurate inventory determination is challenging due to a few factors:Substance orientationSubstance propertiesMeasurement technique
Several RFPs have been granted to develop new technologies to provide better accuracy in 1g and 0g conditions
What’s The Goal?
Develop a non-intrusive, reliable, simple instrument to accurately determine the inventory levelUse ‘dumb’ sensorsUtilize simple physicsTake advantage of ‘random’ nature of fluid
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
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
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
Inventory Location

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
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.
