System and method for assessing fluid dynamics
View Patent ↗Methods and systems for assessing fluid dynamics aspects of corrosion and shear stress in piping networks are provided. Shear stress hot spots of a piping network may be identified using non-dimensional transfer functions that have been developed for identifying the magnitude and location of these local maxima depending upon the geometrical parameters of commonly used components of piping networks, the fluid properties of the flow, and the operating conditions of the piping network. Upon identification of potential shear stress local maxima, piping network operators may monitor these locations for corrosion or other damage to prevent loss of integrity of the pipes.
