Turbulent flux events in a nearly neutral atmospheric boundary layer.
We propose here a novel method of analysing turbulent momentum flux signals. The data for the analysis come from a nearly neutral atmospheric boundary layer and are taken at a height of 4m above ground corresponding to 1.1 x 10(5) wall units, within the log layer for the mean velocity. The method of analysis involves examining the instantaneous flux profiles that exceed a given threshold, for w...
متن کاملAnalytical Solution of The Laminar Boundary Layer Flow over Semi-Infinite Flat Plate: Variable Surface Temperature
In this paper, the problem of forced convection over a horizontal flat plate under condition of variable plate temperature is presented and the homotopy perturbation method (HPM) is employed to compute an approximation to the solution of the system of nonlinear differential equations governing the problem. This paper provides good supplements to the existing literature and generalizes the previ...
متن کاملWSN-Based Space Charge Density Measurement System
It is generally acknowledged that high voltage direct current (HVDC) transmission line endures the drawback of large area, because of which the utilization of cable for space charge density monitoring system is of inconvenience. Compared with the traditional communication network, wireless sensor network (WSN) shows advantages in small volume, high flexibility and strong self-organization, ther...
متن کاملThe near-neutral atmospheric surface layer: turbulence and non-stationarity.
The neutrally stable atmospheric surface layer is used as a physical model of a very high Reynolds number, canonical turbulent boundary layer. Challenges and limitations with this model are addressed in detail, including the inherent thermal stratification, surface roughness and non-stationarity of the atmosphere. Concurrent hot-wire and sonic anemometry data acquired in Utah's western desert p...
متن کاملSNOHATS: Stratified atmospheric turbulence over snow surfaces
Stably stratified turbulence presents particular challenges both from an experimental and a modeling perspective. The damping of the turbulence due to flow stratification and the presence of features such as gravity waves, and Kelvin-Helmholtz instabilities complicate the the application of turbulence similarity theories and the formulation of turbulence models. From an LES perspective, the mai...
