Fluctuations of energy injection rate in a shear flow
We study the instantaneous and local energy injection in a turbulent shear flow driven by volume forces. The energy injection can be both positive and negative. Extremal events are related to coherent streaks. The probability distribution is asymmetric, deviates slightly from a Gaussian shape and depends on the position in shear direction. The probabilities for positive and negative injection a...

متن کاملFlow Estimation of Boundary Layers Using Wall Shear Information
This paper investigates the problem of obtaining a state-space model of the disturbance evolution that precedes turbulent flow and the associated increase in skin-friction drag on aircraft surfaces. This problem is highly challenging since the flow system is governed by nonlinear, partial differential-algebraic equations (the Navier-Stokes equations) for which there currently exists no efficien...
متن کاملEvaluating empirical methods of flood flow rate estimation in Bakhtegan watershed-Iran
Several empirical methods for flood flow rate estimation have been presented. In this study,eight new empirical runoff estimation method including Dredge & Burge, Bourges, Inglis, Faning, Hyderabad, Burkli Ziegler, Cramar and Possenti were calculated in Bakhtegan watershed which is located in Fars province. After studying empirical methods for annual flood flow rate estimation and comparing the...
