开发了一个简单的设计程序，用于确定排气管的必要高度，以便在附近的进气口处产生规定的稀释度。分别考虑了内部系统稀释、风稀释和烟囱高度稀释的影响。将这三种效应结合起来，以确定在产生最小稀释度的临界风速下的可用稀释度。风洞和全尺寸稀释测量用于设定必要的经验常数，并给出了一个样本设计计算。引文:ASHRAE Transactions，1983年，第89卷，pt。华盛顿特区2A。 C

A simple design procedure is developed for determining the necessary height of an exhaust stack to produce a specified level of dilution at a nearby air intake. The contributions of internal system dilution, wind dilution and dilution from stack height are considered separately. The three effects are combined to determine the available dilution at a critical windspeed which produces minimum dilution. Wind tunnel and full scale dilution measurements are used to set the necessary empirical constants, and a sample design calculation is presented.
