摘要
壁龛射流的增压是隧道壁龛式射流通风应用的基础和关键。本文根据壁龛射流的边界条件，进行射流与通风气流之间运动和力的作用关系分析，建立了壁龛射流的增压关系式。该式包括了射流通风的基本要素，壁龛的主要作用条件和影响系数。同时按照壁龛射流增压的基本规律，通过对增压影响因素的全面分析，提出了隧道壁龛式射流通风系统优化设计的一般原则和方法。
In this paper,it is discussed concerned with the pressurization of the jet flow and the optimum design of the ventilation system,which with jet fans are installed in a tunnel niche.Based on the boundary condition of jet flow in a niche and the interaction of jet with air current,a pressurization relation equation have been established.This relation contains the basic factor of jet ventilation and the geometry element of niche.Optimization analyses have been carried on in the ventilation system.The optimum size of niche and the rational layout of jet fans have been put forward also.
