Computational fluid dynamics Simulation and analysis of flow Around mangrove species

Abstract

There are many natural calamities that are occurring in the newlineworld such as tsunamis, mudslides, cyclones, and typhoons. The villages newlinenear the coast are destroyed and many people are dying every year newlinebecause of these calamities. This research work investigates how newlinemangroves can protect the area near the coast from a fluid dynamics point newlineof view. The fluid dynamics of wave flow and wind flow around different newlinemangrove species are investigated. newlineComplex real world problems require intelligent systems that newlinecombine knowledge and techniques. Hence Computational Fluid newlineDynamics (CFD) is employed as a tool in this study. The use of CFD has newlinenot only reduced the need for physical experimentation but it has also newlineimproved design reliability and process development. newlineIn the present study, computational models of two dimensional newlinemangrove roots and three dimensional mangrove tree are generated using newlinethe data from MSSRF, Chennai, India. ANSYS software is used to newlinesimulate the flow. Computational fluid dynamic technique namely finite newlinevolume method is employed to understand flow patterns around the roots newlineand tree. Velocity profiles, pressure distribution and iteration plots around newlinethe roots are captured and presented in detail. newlineA computational model of two-dimensional Pneumatophores newlinemangrove roots is developed initially. A two-dimensional, viscous, newlineincompressible, turbulent water flow under steady and unsteady state newlineboundary conditions is simulated around the roots. Detailed velocity newlineviii newlineprofiles, residual plots, pressure distributions, vectors of the velocity newlinemagnitude and pressure and velocity at different positions around the newlinemangrove roots are obtained to visualize the importance of mangroves in newlinereducing the wave velocity. The simulation outcome confirms that the newlinemangrove roots of mangrove species can reduce the initial velocity of newlinewater flow. The flow patterns and flow structures around the root in the newlinemangrove forest establishes precious data in increasing the effectiveness newlineof current breakwater model. newlineComputational fluid dynamic
