Predicting broadband fan noise is key to reduce noise emissions from aircraft and wind turbines. Complete CFD simulations of broadband fan noise generation remain too expensive to be used routinely for engineering design. A more efficient approach consists in synthesizing a turbulent velocity field that captures the main features of the exact solution. This(More)
BACKGROUND Cardiac catheterization is associated with significant radiation exposure to the operator. Radiation safety employing the As Low As Reasonably Achievable (ALARA) principle includes use of lead shielding to reduce operator exposure. Furthermore, radial approach is now preferred and may be associated with more radiation exposure compared with(More)
