| 摘 要： | 根据轻型客车室内空气三维流动和传热的特点,将空调风道系统纳入计算区域,对车室内流场和温度场的分布进行了数值仿真,并利用环境模拟试验验证了数值方法的可靠性.理论与实验结果表明,客车风道内风量分配主要由风道内的静压分布决定.适当加大风道截面积有利于风量分配,并可避免采用变截面收缩风道而增加的工艺难度.

| Abstract: | A 3 dimensional ventilation model of a light duty bus is established by taking the duct into account. The air velocity and temperature inside the passenger compartment are analyzed numerically and experimentally. Both results show that the cooled air flux of discharges are decided by the steady pressure distribution in duct interior. The uniformity of discharge air can be improved by enlarging the flow area of the duct or using the contractive duct. To simplify the technological process a new duct with 40% flow area enlarged are recommended for the vehicle under study. |
