    Short Wave in the Sea CFD Simulation, Ansys Fluent Tutorial

    In this project, Short Wave in the Sea CFD Simulation has been done using Ansys Fluent software. The purpose of this project is to investigate the ability to simulate short waves with First-Order Airy theory in Fluent software and the VOF model with the open channel wave bc has been used.

    Geometry & Mesh

    The two-dimensional geometry of this project has been produced with SpaceClaim software. The length of the computational area is 210 cm and its height is 76 cm.

    Short Wave CFD Simulation

    To simulate the present model, several assumptions are considered, which are:

    • The solver is pressure-based and transient.
    • Simulation has only examined fluid behavior; in other words, heat transfer simulation has not been performed.
    • The effect of gravity on the flow is considered to be 9.81 m.s-2 and along with the y-axis in the present model.

     The Laminar viscous model has been used to solve the flow field equations, and the pressure-velocity coupling scheme is SIMPLE. The second-order upwind discretization method has been used for momentum and PRESTO! For pressure discretization.

    The following is a summary of the steps for defining the problem and its solution.

    Results

    In Fluent software, it is possible to send waves from the input boundary condition into the domain. According to the speed counters, it is clear that when the waves move at sea level, vortices are created in the surrounding air and it can be said that the intensity of air turbulence is proportional. It is the height of the waves, which is why we see strong winds when we stand by the sea of waves.
