汽车加热器燃烧室最小容积计算

Calculation of the Smallest Volume for the Heater Combustion Chamber for Vehicles

根据加热器燃烧室内气体流动和燃烧特点,提出了一种确定加热器燃烧室最小容积的计算模型。模型以一维流动为基础,假设燃烧室内气体服从理想气体状态方程式。实例计算表明,该方法可以作为加热器系列化设计的参考。

A model for determining the smallest volume of the heater’s combustion chamber is given out on the basis of analyzing the mixture flow and combustion in the heater The model makes a simplification that the mixture flow is one dimensional, and is accorded with the ideal gas state equations. From the calculation results through an example, the conclusion that this method is able to be referred to in the heaters design can be abtained.
