Rationale and Purpose of the Module:
Syllabus:
Mechanical vibrations, simple harmonic and damped simple harmonic motion, quality factor, forced oscillations, coupled oscillations. Waves, transverse and longitudinal waves, phase and group velocity, energy transported by waves, reflection and transmission of waves. Review of the principles orf mechanics: inertial frames, Newtons laws of motion, kinetic and potential energy. Rigid bodies: rotation and moments of inertia, angular momentum and kinetic energy, torque.
Fluid dynamics: Bernoulli equation, equations of motion in integral form, equations of motion in differential form, kinematics, vorticity, potential flow, dimensional analysis, viscous flows, exact solutions, pipe flow, laminar boundary layers, boundary layer solution methods, turbulence. Fluid heat transfer and a thorough understanding of how these disciplines apply to the design and analysis of complex thermal fluid systems.
