空气放大器内部流场数值模拟研究

摘要

Based on operational principles and structural features of air amplifier,computational fluid dynamics software FLUENT was applied to simulate the internal flow field.The result shows that not only can jet Coanda effect be clearly observed, but the mass flow rate of air ejector can also be calculated.%在阐述空气放大器的工作原理及结构特点的基础上，应用计算流体力学软件FLUENT模拟了内部流场，不仅能够清晰观察到射流附壁效应，而且能够计算出引射空气的质量流量。
