Upon completing the course, the students will be capable to: 1. Understand the physics of heat transfer mechanisms 2. Able to describe the fundamental and derived physical quantities, know their definitions, which describe the physics of heat transfer; 3. Understand the conservation of energy, mechanical, internal, and total, formulated in the integral form and in the differential form; 4. Able to interpret the causes and dependencies betweeen physical quantities that characterize a specific mechanism of heat transfer; 5. Understand the concept of dimensionless numbers, which quantify the relative intensity of specific physical phenomena and the circumstances under which it is possibly to simplify the problem of heat transfer in terms of its mathematical treatment; 6. Understand the relevant physical terms and the concept of the boundary layer in the context of the convective heat transfer: Newtons law of cooling, coefficient of convection, boundary layer theory, boundary layer thickness, viscous sublayer, separation, coefficient of friction, etc; 7. Understand the effects of turbulence on the mechanism of convective heat transfer and its effects on: boundary layer thickess, the distribution of temperature and velocity, the friction coefficient, pressure drop, separation point, etc., the complexity in determining the intensity of heat transfer by natural and by forced convection in the general case and the modern approaches for its solution; 8.
