This paper presents experiments and modeling of the most recent set of liquid acquisition device (LAD) vertical outflow tests conducted in liquid hydrogen.
Six 1-g propellant tank outflow tests were conducted with a standard 325 × 2300 rectangular cross-section curved LAD channel conformal to the tank walls over a range of tank pressure (158 221 kPa), ullage temperature (22 39 K), and mass flow rate (0.0103 0.0187 kg/s) per arm.
Mean texture depths (MTDs) of each sample were computed via sand patch and outflow meter tests according to ASTM E 965-12 ASTM ETM E 2380-12, respectively.
The fitness of the stent in the outflow tract was tested for both systole and diastole before the procedure.
Specific conditions for inviscid walls, inflow, and outflow are systematically tested using manufactured and exact solutions to assess well-posedness and stability.
As a result, each test method is able to specify the MTDs with increasing aggregate sizes; whereas 6 mm MTD can be identified as a threshold for implementation of outflow meter test.
An additional simulation named M1 was designed to test the outflow boundary condition setting and its impact on particle distribution.
Two invasive tests are mainly used to select patients affected by NPH for surgery: measuring resistance to CSF outflow and Tap Test.
A total of ∼800 cc of warmed saline with 500 units of heparin per liter was then infused briskly to test inflow, then drained to test outflow.
An inference formula of the xenon outflow curve for six-pulse injection is derived, and the inference formula is also tested to compare with its fitting formula of the xenon outflow curve.
