MONITORING SYSTEM FOR TURBULENCE OF ATMOSPHERIC BOUNDARY LAYER UNDER WIND DRIFT SAND FLOW OR SAND DUST STORM ENVIRONMENT

摘要

A monitoring system for turbulence of the atmospheric boundary layer under a wind drift sand flow or sand dust storm environment comprises: a meteorological tower (6), a hot-wire bracket (9) and a plurality of observation frames (10), which are vertically and cooperatively arranged in parallel. The hot-wire bracket (9) is arranged close to the meteorological tower (6), and the plurality of observation frames (10) are symmetrically distributed on the two sides of a region formed by the meteorological tower (6) and the hot-wire bracket (9). The meteorological tower (6) is cooperatively provided thereon with a first group of experimental instruments for measurements; the hot-wire bracket (9) is cooperatively provided thereon with a hot-wire probe assembly (8); and each observation frame (10) is cooperatively provided thereon with a second group of experimental instruments for measurements. The monitoring system for turbulence of the atmospheric boundary layer under a wind drift sand flow or sand dust storm environment can realize the advantages of measuring a wall turbulence 3D structure with a high Reynolds number, measuring the flow field characteristics of wind drift sand flow or sand dust storm, and synchronizing turbulence measurement with sand dust transport measurement.
