摘要: 射流风机纵向最小间距的确定对于风机正常经济的运行起着十分重要的作用。通过对射流风机工作原理和隧道内流态进行分析,依据射流力学的有关原理找到了影响射流风机纵向最小间距的因素和计算方法。确定射流风机纵向最小间距的计算方法通过工程类比和CFD软件数值模拟验证,符合真实情况,可为今后射流风机纵向最小间距的确定提供指导。

Abstract: The minimum horizontal distance of jet fan is important for jet fan to operate properly and economically. Through the analysis of work principle of jet fan and the air flow in the tunnel based on jet mechanics, the approach of the minimum horizontal distance of jet fan was got. Through the engineering analogy and numerical simulation of the CFD, this method for making sure the minimum longitudinal distance are accordant with the real situation. It can be reference to make sure the minimum longitudinall distance of jet fan.

Key words: highway tunnel, jet fan, minimum longitudinal distance, jet mechanics, numerical simulation
