title = "Low-dimensional description of the flow field over a hemisphere",
abstract = "A study of the flow physics around a cylindrical turret with the application of open-loop control has been performed. The evaluation of flow control performance is accomplished by analyzing the changes in the turbulent flow time/length scales across the turret surface for three cases. Even though these quantities are not direct measures of the aero-optics, literature suggest there is a strong relationship between them. Previous results open-loop results demonstrate reductions in both RMS and Reynolds shear stress over the separated region. Autocorrelations of the unsteady pressure sensors for the actuated low speed tests exhibit a more organized almost periodic behavior. We are interested in developing a low dimensional description of the flow field over a 3D turret through the use of velocity measurements. The use of snapshot POD for two cases: baseline and lumped measurements. Reconstruction of the velocity field using 75% of the energy was accomplished using only 13 and 20% for baseline and lumped POD, respectively.",
