Thermodynamics 2

Also listed as: תרמודינמיקה 2

The second thermodynamics course, where cycles give way to real substances, mixtures and combustion. It is the anchor of the energy track and the reason most energy electives are open to you at all.

  • Thermodynamics 1

Opens up

What it covers

Property relations and real substances

  • Review of the first and second laws, entropy, availability
  • Exergy analysis, second-law efficiency, irreversibility accounting
  • Maxwell relations, the Tds equations, Clapeyron and Clausius–Clapeyron
  • Joule–Thomson coefficient, departure functions, generalised compressibility
  • Cubic equations of state: van der Waals, Redlich–Kwong, Peng–Robinson

Mixtures, combustion and equilibrium

  • Non-reacting gas mixtures, Dalton and Amagat, partial pressures
  • Psychrometrics: humidity ratio, dew point, adiabatic saturation
  • Combustion stoichiometry, air-fuel ratio, enthalpy of formation
  • Adiabatic flame temperature, higher and lower heating values
  • Chemical equilibrium, the equilibrium constant, Gibbs function minimisation
  • Phase equilibrium, the Gibbs phase rule, multicomponent VLE

Advanced cycles

  • Reheat and regenerative Rankine cycles
  • Combined cycles and cogeneration
  • Brayton with intercooling, reheat and regeneration
  • Absorption refrigeration

Results worth carrying out

  • Maxwell relation

    (∂T∂V)S=−(∂P∂S)V\left(\frac{\partial T}{\partial V}\right)_S = -\left(\frac{\partial P}{\partial S}\right)_V

  • Clapeyron

    dPdT=hfgT vfg\frac{dP}{dT} = \frac{h_{fg}}{T\,v_{fg}}

  • Joule–Thomson coefficient

    μJT=(∂T∂P)h\mu_{JT} = \left(\frac{\partial T}{\partial P}\right)_h

  • Equilibrium constant

    Kp=exp⁡ ⁣(−ΔG∘RuT)K_p = \exp\!\left(-\frac{\Delta G^\circ}{R_u T}\right)

  • Exergy of a closed system

    ψ=(u−u0)−T0(s−s0)+P0(v−v0)\psi = (u - u_0) - T_0(s - s_0) + P_0(v - v_0)

Figures worth knowing

  • T–s and P–v diagrams
  • Mollier h–s diagram
  • Psychrometric chart
  • Generalised compressibility chart
  • Equilibrium constant against temperature

The topic outlines are not official syllabi. The university publishes a catalogue blurb per course, not lecture-by-lecture material, so each outline describes what a course of that name, at those hours, with those prerequisites teaches at engineering schools generally, cross-checked against the standard textbook for the subject. Treat it as an informed map, not as a transcript of the lectures.
