An Efficient Model for Flows of Large Number of Particles at Moderate to High Reynolds Numbers and Its Applications

Description :  

In an effort to protect inhabitants in coastal areas and reduce coastal erosion rates, the investigator of this research seeks to examine particle flows at moderate to high Reynolds Numbers (Re). Through a combination of Eulerian and Lagrangian approaches, the investigator`s is to develop a computational model of the flow of 100,000 to 1,000,000 particles using one kernel function per particle, which may be one to two orders of magnitude faster than direct numerical simulation. These particle simulations will be conducted at moderate to high Re, which could be comparable to levels observed in coastal field applications and in coastal erosion. The development of this proposed model could facilitate the prediction of sediment transport, mitigate coastal erosion, and improve environmental management.
