This paper describes an electrically calibrated plethysmograph which may be used with all lengths of mercury-in-rubber strain gauges. Due to the very low resistance these gauges, electrical calibration previously available plethysmographs has suffered from errors caused by lead-wire resistance. The present instrument eliminates a design effectively places gauge at corners measurement bridge. Linearity output for large changes in been insured incorporation constant-current bridge supply.

The flow around two circular cylinders of equal diameter, arranged in a staggered configuration, was investigated using visualization and particle image velocimetry for centre-to-centre pitch ratio P / D = 1[ratio ]0 to 5.0 angle incidence. α 0° 90°. Experiments were conducted within the low subcritical Reynolds number regime, from Re 850 1900. Nine patterns identified, processes shear layer reattachment, induced separation, vortex pairing synchronization, impingement, observed. New insight...
