Volumes released

Only what nuclear thermal-hydraulics actually uses, starting from why each equation looks the way it does.

A thermal-hydraulics trilogy

The three volumes share one set of symbols and one chapter structure. Thermodynamics fixes the states, fluid mechanics supplies the velocity field, and heat transfer gives the temperatures. We suggest reading them in that order.

Essential Thermodynamics

Twelve chapters on the way to nuclear thermal-hydraulics

The question it answers
How much energy moves, and how far can it go

It starts with reading a steam table and works a full Rankine cycle by hand. Chapter 7, on exergy, is the heart of it: energy is conserved, so why does a plant stop at 33%, and where exactly is the capacity to do work lost?

Chapters

  1. 1A map of thermodynamics
  2. 2States of a pure substance — reading steam tables
  3. 3First law — closed systems
  4. 4First law — control volumes
  5. 5Second law and entropy
  6. 6Isentropic efficiency and real machines
  7. 7Exergy — where the capacity for work was lost
  8. 8The Rankine cycle — the body of nuclear power
  9. 9Improving the cycle — reheat, regeneration, moisture separation
  10. 10Gas power cycles — Brayton and supercritical CO₂
  11. 11Equations of state and real fluids
  12. 12Thermodynamics of reactor systems

Essential Fluid Mechanics

Twelve chapters on the way to nuclear thermal-hydraulics

The question it answers
How does the fluid move

The equations were all written two centuries ago, and nobody knows the general solution yet. So this is a field not of “solved” but of “how far did we approximate”. The book follows that lineage of approximations: what was thrown away, and what was gained.

Chapters

  1. 1How to look at a fluid
  2. 2Fluid statics — force without motion
  3. 3Control volumes and conservation laws
  4. 4Bernoulli and its limits
  5. 5Differential equations — continuity and Navier–Stokes
  6. 6Dimensional analysis and similitude
  7. 7Viscous pipe flow and friction
  8. 8Minor losses and pipe networks
  9. 9Boundary layers and external flow
  10. 10An introduction to turbulence
  11. 11Two-phase flow and compressibility
  12. 12Flow measurement and visualization

Essential Heat Transfer

Twelve chapters on the way to nuclear thermal-hydraulics

The question it answers
How fast does heat move

It takes the states and velocity fields set by the other two volumes and turns them into temperatures. From the temperature profile inside a fuel rod (ch. 4) to the critical heat flux in pool boiling (ch. 11), ending at the place that actually limits reactor power.

Chapters

  1. 1A map of heat transfer — what thermodynamics cannot do
  2. 2Conduction basics — Fourier's law and thermal resistance
  3. 3Resistance networks and fins
  4. 4Conduction with heat generation — fuel rod temperature
  5. 5Transient conduction — how fast does it respond
  6. 6What convection really is — boundary layers and dimensionless numbers
  7. 7Forced convection — pipe flow and subchannels
  8. 8Natural convection — Ra and passive cooling
  9. 9Radiation heat transfer
  10. 10Heat exchangers — LMTD and effectiveness–NTU
  11. 11Pool boiling and critical heat flux (CHF)
  12. 12Flow boiling and two-phase flow

If you need more

We keep deeper material too: turbulence models, conjugate heat transfer in CFD, the spectral element method.
