本文从工质均匀混合的假定出发,并在定压增压情况下考虑到进、排气口处可能存在的压力脉动,建立工质更换的数学模型,编制了一个用于二程机的计算程序.计算结果表明,在弯流扫气情况下,仍可采用均匀混合扫气模型.
Based on the assumption of uniform mixture of working fluid and taking into account the pressure pulsations that may exist at inlet and exhaust ports under constant pressure and pressure increase, a mathematical model for the change of working medium was established and a calculation for two-way engine was made The calculation results show that the homogeneous mixed scavenging model can still be used in the case of sweep sweep.
