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...

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,...

When Keiko is born, she looks beautiful, except for one thing. A bright, red mark adorns her right cheek. It isn't large and it doesn't hurt, but still people stare at Keiko with great curiosity.

At two years old, Keiko notices the spot on her cheek. Her mother says it's a sign she's going to be a great artist someday. Keiko tries to fulfill that prophecy, but she becomes frustrated when her efforts don't produce beautiful works. For a time, she withdraws, feeling sad and angry. But her friends convince her she can be wise and happy. Keiko spends her time with moon, tree, and snow,...
