Dynamic surface-pressure instrumentation for rods in parallel flow

Measurement of Steady and Unsteady Hydrodynamic Loads on a Nuclear Fuel Bundle

“…More recently, Curling & Paidoussis (1992) have measured turbulent pressure correlations between different cylinders in a multi-cylinder cluster. While most investigators used matched pairs of miniature pressure transducers diametrically opposed in the cylinder walls [e.g., Mulcahy et al (1982) and Wambsganss & Zaleski (1970)], Gorman (1971) used two differential pressure transducers each connected to the opposite sides of the exterior flow tube.…”

Measurement of crossflow forces on tubes

“…The transducer material chosen was 17-4 Ph stainless steel whose yield stress 7.585 x 10^ Pa (110,000 psi) was more than twice that expected according to (6), again desirable to avoid nonlinear transducer material behavior [11]. The expected sensitivities of the transducer according to (4) and 5were determined to be AV ™£= 3.91 x 10" 5 N" 1 (1.74 x 10" 4 lb" 1 )…”

Crossflow force transducer. [LMFBR]

“…The difficulty, of the forc;e-ring transducer is that rather complicated multicomponent sensing devices must be constructed in a small space for a wide variation in the character of the forces. However, a force-ring transducer was sought because of the difficulties in maintaining time references and amplitude scaling in the integration of pressure to obtain re'sultant forces, and because measurement of p.t:ez:HluJ•es• in pressurized water also r~;>qn:f.r.es considerable instt'ullie11tation effort and interpretation of the data [4]. The interaction of the turbulence with the shed vortices is the subject of current research for which the force transducer is intended.…”
