摘要
提出将Lax Wendroff数值方法应用于脉管制冷机气体流动和工作过程的数值模拟。分析了属于Lax Wendroff数值方法类型、具有 2阶精度格式、 2阶段MacCormack算法及其相应的离散格式和算法组织。所进行的研究表明 ,将Lax Wen droff算法类型应用于数值计算脉管制冷机工作过程所伴随的强烈热交换和流动损失现象的气体流动 。
Lax Wendroff scheme applied for numerical simulation of pulse tube refrigerator is proposed in this work.Maccormack algorithm,which is one kind of two step Lax Wendroff scheme with second order accuracy,is investigated and applied to simulate an orifice pulse tube refrigerator.It is turned out that Law Wendroff scheme can achieve better algorithmic stability to numerically simulate the gas flow with strong heat transfer and flow loss in pulse tube refrigerator.
