Turbulence is the most common state of fluid flow in a wide range of technologies and natural conditions. Formally it is defined as "an eddy-like state of fluid motion where the inertial-vortex forces are larger than any other forces that tend to damp them out". Turbulence then, is a nonlinear force that works to scramble a flow of fluid or gas either in nature or in an industrial system. Turbulence is strongly diffusive in nature and industrial systems take advantage of this property to diffuse heat or to mix chemicals. Examples in nature could be the turbulence encountered by an aircraft in an area of shearing winds or in undertow forces in the ocean. Industrial systems examples could be the flow through a pipe that is partially obstructed, or the forces displayed in a chemical mixing tank. Bernard's book provides a thorough yet focused introduction to the principle trends in turbulent flow analysis for students studying this topic and turbulent flow prediction for practicing engineers.
