The surface of wind turbine blades are prone to degradation due to exposure to the elements. Rain, hail, insects are among the many causes of turbine blade degradation or erosion. Surface degradation of the wind turbine blades leads to a reduction in the aerodynamic performance, resulting in power losses. The effect of surface degradation is...

Nowadays, pollution from traffic remains one of the major sources for contamination in urban areas and it is widely known that substances emitted by vehicles represent a serious hazard to human health; some traffic-related pollutants, such as NO, NOx and CO are responsible for both acute and chronic effects on human health. This is often the...

Five root-mean-square (RMS) pressure models are used in combination with different turbulence models to determine whether it is possible to obtain a conservative estimate of RMS pressures on a high-rise building model from a RANS calculation. When a precursor domain is used for the generation of inlet profiles the turbulent kinetic energy is...

In this paper an engineering method for the prediction of noise generated by a turbulent flow is presented. The presented approach is based on the assumption that the acoustic phenomena do not provide feedback to the turbulence. Thus, parameters such as the turbulent kinetic energy and the integral length scale can be obtained from Reynolds...
