Large Eddy Simulation of Air Flow around the Air-Sea Interaction Tower

Abstract

The dynamics of the coupled marine boundary layer (MBL) are driven by multiscale and multiphase processes. A thorough understanding of these processes would have a profound impact on Naval worldwide operations. The coupled MBL dynamics are classified into three regimes: low wind (wind speed less than 5m/s), high wind, and hurricane. In order to study the MBL under the low-wind condition as part of the Coupled Boundary Layers and Air-Sea Transfer (CBLAST) program, the Air-Sea Interaction Tower (ASIT, Fig. 1(a)) has been constructed off the south shore of Martha's Vineyard. The long-term goal of the project is to investigate the flow around the ASIT by large-eddy simulation (LES) technique and to help field experimenters interpret their data measured around the tower. The flow distortion around the Floating Instrument Platform (FLIP), which is a 355-foot (108-meter) spoon-shaped buoy (Fig. 1(b)) will be simulated and studied as well using LES.
