 ANNOUNCEMENT “Dalam kuliah ini peserta yang datang lebih dari 10 menit setelah kuliah dimulai, maka dianggap tidak hadir. Dan bagi peserta yang tidur atau berisik dipersilahkan meninggalkan kelas.”
Course Description and Aims
In the early part of this course, we will review the concept of fluid, kinematics, and fluid element movement. Two important concepts on conservation of mass and momentum will be discussed in more details. The explanation will be deeply explored in the area of Navier-Stokes Equation. Derivation of Eulerian and Lagrangian form on the Navier Stokes will be explained. Supplementary material to Introduction of Turbulency, and Introduction of Geophysics Fluid Dynamic (GFD) can be covered as long as the time permit.
Course Outcomes
1. Ability to explain basic concept in hydrodynamics, such as continuum and mass elementary concepts from previous class of OS-2102 (Fluid Mechanics), and identify governing equation in fluid motions.
2. Ability to analyze element of motions such as translation, dilatation, angular deformation, and rotation.
3. Ability to demonstrate the Reynold Transport Theorem, which explains concept between Lagrangian and Eulerian methods.
4. Ability to explain the concept of mass conservation from Reynold Transport Theorem and explain main characteristics of Continuity Equation as consist as below:
• Compressible vs Incompressible fluid
• Divergence theorem
5. Ability to display the concept of momentum conservation for long waves (i.e tides or Tsunami) in fixed or slow-varying topography from the following:
• Inertia forces, including geostrophic acceleration
• Applied forces: surface forces (Pressure, stress, viscous) , body forces (gravity and buoyancy)
6. Ability to apply inertia forces to kinetics and rotation terms and demonstrate that the geostrophic acceleration is part of inertia forces.
7. Ability to apply pressure and gravity term, stress/viscous term as main terms in the applied forces of the Newton’s second Law.
8. Ability to demonstrate and analyze the Navier-Stokes equation based conservation of mass and momentum equation for ocean applications.
Keywords
Concepts on conservation of mass and momentum, Navier Stokes Equation, Eulerian vs Lagrangian Equation, Position-displacement-velocity-acceleration.
Competencies that will be developed
Intercultural skills Communication skills Specialist skills Critical thinking skills Practical and/or problem-solving skills
Class Flow
Mostly the Professor prepared material and sylabus. However, the class is openned for discussion and question in the middle of the lecture is surely welcomed.
