STUDY OF RECIRCULATING FLOW AROUND COASTAL STRUCTURE BY USING LABSWETM

Breakwaters that are built at coastal area is a type of hard protection measure to protect
the coastline, port, harbour or estuaries from the hydrodynamic effects due to severe
waves condition. However, the presence of breakwaters will disrupt the natural
condition of flow by dissipating, reflecting and refracting the incoming waves to
produce calmer waves at the leeside of the structure. Thus, the flow separation occurs
due to the blockade of breakwater which forming the recirculating flow inside the
breakwater. This study is to simulate the recirculating flow around the breakwater at
Chendering Fishery Port, Terengganu, Malaysia by using Lattice Boltzmann Method
for shallow water equation with turbulence modelling (LABSWETM). The results of
recirculating flow are analysed in the perspective of flow pattern and flow velocity.
