Method Of Simulating Flow-Through Area Of A Pressure Regulator

View page
US Patent:
20090287460, Nov 19, 2009
Filed:
Jul 7, 2005
Appl. No.:
11/177664
Inventors:
Neal E. Hass - Yorktown VA, US
Paul A. Schallhorn - Indialantic FL, US
Assignee:
USA as represented by the Administrator of the National Aeronautics and Space Administration - Washington DC
International Classification:
G06F 17/10
G06G 7/48
US Classification:
703 2, 703 9
Abstract:
The flow-through area of a pressure regulator positioned in a branch of a simulated fluid flow network is generated. A target pressure is defined downstream of the pressure regulator. A projected flow-through area is generated as a non-linear function of (i) target pressure, (ii) flow-through area of the pressure regulator for a current time step and a previous time step, and (iii) pressure at the downstream location for the current time step and previous time step. A simulated flow-through area for the next time step is generated as a sum of (i) flow-through area for the current time step, and (ii) a difference between the projected flow-through area and the flow-through area for the current time step multiplied by a user-defined rate control parameter. These steps are repeated for a sequence of time steps until the pressure at the downstream location is approximately equal to the target pressure.
