Fluid Dynamics and Heat Transfer

Course Description

Heat sources. Heat conduction in solids with and without an internal heat source. Basics of hydrodynamics. Laws of conservation of mass and momentum. Mass transfer. Heat convection. Heat transfer coefficients for natural and forced circulation. Heat transfer during phase-change (evaporation and condensation). Heat transfer by radiation. Heat exchangers and cooling towers. Numerical methods in heat and mass transfer (finite difference method, finite element method, finite volume method). Cooling of electrical and electronic equipment. Gas-vapour mixtures and air conditioning. Modeling of laminar and turbulent flows. Analyzes of operation of steam, gas, water and wind turbines.

Learning Outcomes

  1. Analyze heat transfer in energy devices during the steady state and time-varying conditions
  2. Calculate heat transfer from solids to different types of fluid in forced and natural circulation
  3. Analyze cocurrent and countercurrent flow heat exchangers
  4. Compare the heat transfer to single-phase and two-phase fluid, during evaporation and condensation, and nucleate and film boiling
  5. Solve the equations of conservation of mass and momentum of fluid motion for simple examples in power engineering
  6. Apply fluid dynamics laws in the modeling of steam, gas, water and wind turbines
