Prediction of turbulenceinduced forces on structures from full numerical solutions of the NavierStokes equations
Abstract
The wall pressure fluctuations generated by a turbulent boundary layer are the driving forces in a variety of fluidstructure interaction problems of fundamental and practical interest. Historically, these surface pressure forces have been determined by conducting appropriate laboratory experiments and scaling the results as needed. The present paper examines the potential utility of full numerical solutions of the NavierStokes equations for turbulent flows to accomplish this same end. An overview of the means employed for obtaining such solutions without resort to closure assumptions is given. Comparisons between the predicted and measured characteristics of the wall pressure and velocity fields are described which are quite favorable and commend the use of numerical simulations as an aid in understanding flowinduced vibration phenomena. Fundamental limitations of the numerical simulations and additional areas of research needed to make them more generally applicable in predicting turbulenceinduced forcing functions are also discussed in detail.
