Unit Description and General Aims

Thermodynamics is a central branch of science that examines energy and its manifestations, specifically the driving forces of energy exchange and the conditions on which they exist. The main concern is with the amount of energy transfer – in the form of heat or work – which will take place in a system as it undergoes a change from one state to another or from one form to another; there is no indication about how long the process itself will take.

Heat transfer, is a branch of science that utilises the framework laid down by the Laws of Thermodynamics. It relates specifically to heat energy and how heat is transferred from one body to another.

Heat can only be transferred when a temperature gradient exists in a system, and this gradient itself is an indication of non-equilibria phenomena. In heat transfer, there is a requirement to know the ‘how’ and ‘when’ of the heat energy redistribution, hence, the rate of heat energy transfer within a process is critical.

An understanding of thermodynamics and heat transfer is central to ensuring good process design and safe operation. Separation processes are driven by the principles of heat transfer and Vapour Liquid Equilibria (VLE), knowledge of heating and cooling systems and related equipment is key to this work, hence, these and other areas will be examined in detail throughout this unit and at the conclusion, students will have been enabled to comprehend and effectively utilise these two branches of science that underpin all process engineering operations.

Learning Outcomes

On successful completion of this Unit, students are expected to be able to:

  1. Demonstrate thorough knowledge of the conceptual and physical properties of thermodynamics and heat transfer processes.
  2. Interpret and apply in design the concepts of irreversibility, entropy, and heat cycles.
  3. Effectively utilise VLE and Liquid Equilibria (LLE) conditions.
  4. Define and apply in design the heat transfer principles including boundary systems.
  5. Distinguish between the different types of heat transfer equipment with a focus on heat exchangers and furnaces.
  6. Investigate practical industrial problems so as to apply the Laws of Thermodynamics and heat transfer equations to obtain effective and efficient solutions.
