Abstract
A wireless sensor system is described. Pressure sensor measurements are compared with National Weather Service data and wind tunnel test data. It then describes a minivan highway test that was used to evaluate the effect of sensor housing shape on pressure measurements. Computational Fluid Dynamics (CFD) analysis was also performed to complement the wind tunnel and road van tests, as well as to determine optimal mesh shapes and sizes, boundary conditions, and the best turbulence model that would reproduce the measured pressures. (UV) The following describes the Hurricane Simulator tests that were used to evaluate the effect of wind gusts on pressure and automatic/cross-correlations of pressure and velocity between different sensors. A CFD simulation of the UF Hurricane Simulator test was also performed to evaluate the sensitivity of turbulence models in capturing true pressure and velocity changes on the test site due to gusts. Vibration testing using a shaker table to analyze the effect of structural vibration on sensor pressure measurements is described.
