【摘要】 主要对新型等截面静压均匀送风道的送风机理进行了分析研究,即根据有关流体力学知识建立了其送风流动微分方程组,并详细分析其主风道内流速变化规律、主风道内静压分布规律及其变化特点;通过不同送风工况下所测得的静压值与对应送风工况下所确定的理论静压计算值的比较,规律基本相符,并提出了进一步改善此送风道送风性能的措施.更多还原

【Abstract】 In this paper the performance of uniform static pressure ventilating duct is analyzed on the basis of flow dynamics ,and its mathematic model offlow is deduced on the analyzing basis.At the same time the law and specialty of velocity’s variation and static pressure in the main ventilating duct are studied. In the end through the experiments the result of analysis is testified and the improving measures for the duct are pointed out.更多还原
