CE3042 Ocean Wave Dynamics Syllabus:

CE3042 Ocean Wave Dynamics Syllabus – Anna University Regulation 2021

COURSE OBJECTIVE

 To make the students be aware of ocean wave classification, the mass, momentum and wave energy transformations and wave kinematics that are happening in nature and enable them in the prediction and analysis of the wave data.

UNIT I CONSERVATION EQUATIONS OF FLUID FLOW

Basic equations – Conservation of mass, moment and Energy – Continuity Equation, Euler’s Equation, Newtonian Fluids, Navier-Stokes Equation.

UNIT II WAVE THEORIES

Linear wave theory : Governing Equation, Boundary Conditions and solutions, Dispersion relation, Constancy of wave period. Introduction to non-linear wave theories – Stokes, Cnoidal and Solitary wave theory.

UNIT III WAVE KINEMATICS

Wave celerity, water particle velocities, accelerations, displacements and pressures. Integral properties of waves: Mass flux, Energy and energy flux, Group speed, Momentum and momentum flux.

UNIT IV WAVE TRANSFORMATIONS

Shoaling, bottom friction and damping, refraction, reflection and diffraction. Wave Breaking: Type of breaking, Surf similarity parameter. Keulegan-Carpenter number, Ursell Parameter, Scattering parameter, Reynolds Number

UNIT V WAVE ANALYSIS

Short term wave analysis- Short term wave Height Distribution – Wave period Distribution – Time and Frequency domain Analysis of Wave Records – Long term wave analysis – Gumbel Distribution – Weibull Distribution – Statistics analysis of grouped wave data.
