This volume authoritatively treats viscous drag reduction in four major categories--laminar flow control, passive turbulent drag reduction, active turbulent drag reduction, and interactive turbulent drag reduction--and presents emerging technologies, such as the use of surfactants, as an alternative to polymers. It gives a designer's view of the NASA Laminar Flow Control Program and the innovation of riblet application to transport aircraft. The section on active turbulent drag reduction treats MHD flow drag reduction, drag reduction by polymers and surfactants, drag reduction by particle addition, and viscous drag reduction via surface mass injection
