Turbulent multiphase flows with heat and mass transfer / Fabien Anselmet, Roland Borghi.
Numerous industrial systems or natural environments involve multiphase flows with heat and mass transfer. The authors of this book present the physical modeling of these flows, in a unified way, which can include various physical aspects and several levels of complexity.Thermal engineering and nucle...
