PRESSURE TRACES RECORDED DURING CA0RSO SINGLE VALVE TESTS WERE GROUPED AS FOLLOWS:
o MULTIPLE FREQUEllCY PRESSURE (NFP) WAVE FORM TYPE o
SINGLE FREQUENCY PRESSURE (SFP) WAVE FORf1 TYPE i
l
e MFP WAVE FORM CHARACTERISTICS:
o RICH IN FREQUE' ICY CONTENT IN THE RANGE OF 15 Hz TO 40 Hz (FRONT END OF TRACES) o A DOMINANT SINGLE CHARACTERISTIC FREQUENCY IN THE RANGE OF 6 Hz TO 10 Hz (TAIL END OF TRACES).
o NEGLIGIBLE FREQUENCY C0flTENT IN THE RANGE > 40 Hz.
o RANDOM PROPERTIES:
PRESSURE AMPLITUDE AND FREQUENCY CONTENT.
SFP WAVE FORM CHARACTERISTICS:
o EXHIBITS PRIMARILY A SINGLE DOMINANT CHARACTERISTIC FREQUENCY IN THE RANGE OF 6 Hz TO 10 Hz.
o SMALLER CONTRIBUTIO.1 (THAN MFF'S) IN THE RANGE OF 15 Hz TO 40 Hz.
o NEGLIGIBLE FREQUENCY CONTENT IN THE RANGE > 40 Hz.
o RANDOM PROPERTIES:
PRESSURE AMPLITUDE AND FREQUENCY CONTENT.
CORRR ATION ANALYSIS OF RECORDED BOU.51DARY PRESSURES T'd0 TYPICAL TESTS WERE CONSIDERED:
o TEST 502 (MFP WAVE FORM TYPE), AND o
TEST 2202 (SF? WAVE FORM TYPE).
MATRIX OF CROSS-CORRELATION COEFFICIENTS F0P.
PRESSURE TRACES RECORDED BY SENSORS P 9, P13, P14, P11 AND P10 WAS CALCULATED.
RESULTS OBTAINED INDICATE NEAR PERFECT CORRELATION ONLY AT 17= 0.
CONCLUSIONS:
TEMPORAL BEHAVIOR IS INDEPENDENT OF SPATIAL DISTRIBUTION o
FOR MEASURED BOUNDARY PRESSURES, t.e.,
P(R,T) = PC,a)
- T(T) 1 o
'dATtR IN SUPPRESSION POOL MAY BE ASSUMED AN INCOM-PRESSIBLE FLUID.
