Synopsis

Momentum, heat, and mass transfer are usually taught as three separate subjects, in three separate courses, from three separate books. An engineer finishes that sequence able to compute a friction factor and a heat-transfer coefficient, yet unable to see that the two calculations share a structure. Then a real problem arrives in which a fluid is moving, a wall is hot, and a species is crossing an interface at once, and there is no method available, only three disconnected habits.

The knowledge is not missing. It is fragmented. Correlations get applied outside the range they were fitted in, because nobody explained what the range meant. Dimensionless groups get treated as algebra rather than as statements about which mechanism is winning. A simulation returns a plausible colored picture and no one can say whether it deserves to be believed.

This comprehensive twenty-two-chapter reference treats transport as one discipline with three expressions. One sequence is stated at the outset and never abandoned: write a conservation balance, identify every mechanism crossing the boundary, supply a constitutive law linking flux to gradient, estimate the scales, solve with the simplest adequate method, and verify the result. Read it straight through, or open it at one of its two hundred numbered sections when a specific answer is needed.

Inside this book you will

  • Build one reusable analysis method that survives the move from a pipe to a packed bed to a porous electrode, instead of memorizing a recipe for each.
  • Read dimensionless ratios as comparisons of competing mechanisms, so correlations become interpretable rather than arbitrary, including near the edges of their fitted range.
  • Work momentum transport from viscosity and rheology through exact laminar solutions, the equations of viscous flow, boundary layers and drag, pipe networks, and turbulence closure.
  • Develop conduction, convection, radiation exchange, and buoyancy-driven flow in parallel with momentum, so the correspondence is demonstrated rather than asserted.
  • Handle diffusion, reaction, interphase transfer, and separation contacting, including the reference-frame subtleties that make species transport harder than a borrowed heat result.
  • Judge a computation properly: choose a discretization, test grid independence, inspect conservation residuals, and separate numerical error from model error.
  • Carry uncertainty through property data, correlation scatter, and design margin, rather than hiding it inside a safety factor.

Key topics: conservation balances in integral and differential form; rheology and constitutive-model selection; laminar and turbulent flow; pressure drop and flow networks; conduction; forced and natural convection; radiation in enclosures; multicomponent diffusion; catalyst effectiveness; interphase transfer and separation contacting; coupled transport with phase change; porous, electrochemical, and transient biological systems; computational fluid dynamics; and verification, validation, and uncertainty quantification. batteries, hydrogen, carbon capture, and biomedical transport.

More than sixty figures each carry a specific argument, and the apparatus includes a nomenclature of symbols and dimensionless groups, a glossary, and an index keyed to section numbers rather than pages.

Who it is for: practicing chemical, mechanical, process, energy, and biomedical engineers whose designs depend on getting transport right; simulation engineers who must justify a computed result; and readers taking or teaching a first course who want the three modes as one subject.

Open the book and begin building the one method that turns momentum, heat, and mass transfer from three catalogs of equations into three connected ways of reading how engineering systems move what they carry.
