08.128.794 Fluidmechanics and Biomechanics

Lecture / Lab

Summer term 2017, Begin: Apr. 18.

Lectures: Tuesday 14:15-15:45, IMB Mainz, Ackermannweg 4, IMB Seminar room, 2nd floor
Tutorial: Wednesday 13:00-14:30 (tbc), Institut für Physik, Staudingerweg 7, CIP pool 03.423
Lecturers: Dr. Udo Birk, Prof. Dr. Christoph Cremer
Teaching language will be English, unless otherwise specified.

In the tutorials, advanced concepts of modeling and simulation of the topics discussed in the lectures will be applied, based on the programming environment MATLAB. Students will be given exercises to model the physical processes discussed during the lectures, and to evaluate the potential of the underlying model.

In the lectures to Fluidmechanics, the following topics will be covered:

1.- Introduction to fluid mechanics
1.1. Solids, liquids and gases
1.2. The continuum hypothesis
1.3. Density, velocity and internal energy
1.4. Local thermodynamic equilibrium. Equations of state.
2.- Kinematics of the fluid flow
2.1. Eulerian and Lagrangian descriptions
2.2. Uniform flow. Steady flow. Stagnation points. 
2.3. Trajectories. Paths. Streamlines.
