While one can attempt DNS of Navier-Stokes equation for fully developed turbulent flow, there would be ambiguity about specifying initial and boundary conditions. Moreover, such

Based on these principles, Claude-Louis Navier and George Gabriel Stokes, derived the governing equation for viscous fluids by applying Newton’s second law to fluid motion, along with the assumption that stresses arising in the fluids are due to diffusing viscous effects and the pres

This assumption implies that the equilibrium flow quantities do not grow in the streamwise direction and requires solving the Orr-Sommerfeld equation (OSE) to study evolution of disturbance field in a linearized analysis. The concept of the spatio-temporal wave-front (STWF)originates from
