Fluid forces acting on a tube array are important in the assessment of vibration of system components consisting of multiple circular cylinders. This paper presents test results for a square tube array with the pitch-to-diameter ratio of 1.75 subject to turbulent flow. The fluctuating drag and lift forces are measured as a function of Reynolds number, incoming flow conditions, and tube location in an array.
