Short Description:
- Our fluid environment (atmosphere, oceans, Earth, Sun, planets, and stars).
- Fluid properties, equations of state for gases and liquids.
- Viscosity, shear velocity, boundary layers and free flow zones.
- Newton’s rheological law. Flow types, turbulent flow, turbulent vortices. Boundary layer separation and bodies’ wake.
- Flow velocity convergence – divergence, physical meaning and environmental results.
- Flow field and its Eulerian and Lagrangian description.
- Flow of volume, mass, heat, kinetic energy, and other properties. Aeolic power and energy.
- The continuity equation and its applications in the Geophysical fluid flows.
- Hydrostatic equilibrium. Fluid bodies’ internal structure under hydrostatic equilibrium.
- General description of the Atmosphere, Oceans, and Earth’s internal structure.
- Accelerations acting on fluid volume elements. Equations of momentum and energy. The equation of Navier-Stokes.
- Solvability of the fluid dynamics equations in the framework of computational fluid dynamics (an introductory reference to flow domain geometry, mesh, equations discretization, turbulence models, initial and boundary conditions, solution, post-processing and flow field mapping, solution validation).
- Geostrophic equilibrium, geostrophic flow, and the influence of friction.
- Cyclonic and anti-cyclonic flow. The differential equation of Euler, the equation of Bernoulli and its applications.
