Since 1999, we have repeatedly surveyed the central Apennines through a dense survey-style geodetic network, the Central Apennines Geodetic Network (CAGeoNet). CAGeoNet consists of 123 benchmarks dist...
果树喷雾用圆盘风扇三维气流速度场数值模拟与验证（Numerical Simulation and Experimental Verification of 3-D Air-velocity Field of Disk Fan Used in Orchard Sprayer）
果树 仿形喷雾 圆盘风扇
2010/12/29
为研究用于果树风送喷雾的圆盘风扇气流速度场分布特性，采用k-ε紊流模型和稳态求解方法，设置合适的边界条件，对单、双风扇不同出口风速的气流速度场进行三维稳态数值模拟和试验验证。结果表明，双风扇同时送风时，在离两风扇中心1~3m的范围内，中心区域的风速明显小于两边的风速，在3~5m的范围内中心区域的风速和两边的风速相差不大。模拟值与试验值对比表明变化趋势一致，二者的拟合直线决定系数R2分别为...
A Slight Excess of Large Scale Power from Moments of the Peculiar Velocity Field
