The course objective is for students to acquire competency to carry out technical computation in the area of thermodynamics and heat transfer. Students will apply theoretical knowledge to machinery and technological fields. Students will acquire skills to carry out technical computation in the area of thermodynamics and heat transfer : Computation of heat engines and cooling systems. Heat balance of material and machine systems, in gases, vapors, buildings and technological processes.
The course is concerned with the following topics: Basic quantities of state. Equation of state of an ideal gas. Mixtures of ideal gases. The First Law of Thermodynamics- heat, work, internal energy, enthalpy. The Second Law of thermodynamics, entropy. Reversible and irreversible processes of ideal gases. The thermodynamics of vapour. Vapour tables and diagrams. The Clausius-Clapeyron Equation. Thermodynamic processes in vapours. Thermodynamics of humid/atmospheric air. Definitive quantities, tables, diagrams. Isobaric arrangements of air, evaporation from a free surface. Thermodynamics of flow of gases and vapors. Adiabatic flow through nozzles. The cycles of heat gas and heat steam engines. Compressors. The cycles of cooling devices and heat pumps. Fundamentals of heat transfer. Stationary and transient heat conduction, internal sources. Heat transfer by convection, similarity theory.
