Há 1 hora · Abstract. In Chapter 12 unsteady pipe flow is discussed by means of the method of characteristics for which the underlying basic equations are derived at first. These are the continuity and energy equations according to Alliévi and their solutions by Riemann as well as the unsteady momentum equation. A problem that is solved step by step ...
Há 1 hora · 1) RANS models can be used to provide initial conditions or boundary conditions for LES simulations, particularly in regions where the flow is less unsteady or complex. 2) Hybrid RANS-LES approaches, such as Detached Eddy Simulation (DES), can be employed to combine the efficiency of RANS modeling in the near-wall regions with the accuracy of LES in the separated or highly turbulent regions of ...
Há 1 hora · Renewable energy resources are playing a crucial role in minimizing fossil fuel emissions. Integrating machine learning techniques with tidal power forecasting could greatly enhance the accuracy and reliability of predictions, which is crucial for efficient energy production and management. A hybrid approach combining different methods often yields better results than relying on individual ...
