The book provides the theoretical fundamentals on turbulence and a complete overview of turbulence models, from the simplest to the most advanced ones including Direct and Large Eddy Simulation. It mainly focuses on problems of modeling and computation, and provides information regarding the theory of dynamical systems and their bifurcations. It also examines turbulence aspects which are not treated in most existing books on this subject, such as turbulence in free and mixed convection, transient turbulence and transition to turbulence. The book adopts the tensor notation, which is the most appropriate to deal with intrinsically tensor quantities such as stresses and strain rates, and for those who are not familiar with it an Appendix on tensor algebra and tensor notation are provided.

This book gathers ten thermofluid dynamics problems involving the use of analytical solutions. All these problems have been encountered by the author during his research activity; some of the solutions are his own contributions, while others either are classic literature results or can be derived from them. The physical phenomena involved range from pure hydrodynamics to flow with heat or mass transfer, two-phase flow, and magnetohydrodynamics. The problems discussed are not canonical problems; they are rarely found in textbooks, and often exhibit surprising, or even paradoxical, solutions. The potential readership of the book includes students, teachers and scientists in science and engineering interested in fluid dynamics and heat/mass transfer: to them it may offer food for thought, suggestions for lectures or tutorials and ideas for further original developments.

Questo libro raccoglie dieci problemi di termofluidodinamica che richiedono l''uso di soluzioni analitiche. Tutti i problemi discussi sono stati affrontati dall''autore durante la sua attività di ricerca, alcune delle soluzioni sono un suo contributo, mentre altre sono risultati classici della letteratura o possono essere derivate da essi. I fenomeni fisici coinvolti vanno dall''idrodinamica pura al flusso con trasferimento di calore o di massa, al flusso bifase e alla magnetoidrodinamica. I problemi discussi non sono canonici; si trovano raramente nei libri di testo e spesso presentano soluzioni sorprendenti o addirittura paradossali. I lettori potenziali del volume sono studenti, docenti e scienziati in campo scientifico e ingegneristico interessati alla fluidodinamica e al trasferimento di calore/massa: a loro potrà offrire spunti di riflessione, suggerimenti per lezioni o esercitazioni e idee per ulteriori sviluppi originali.
