摘要
对焦平面探测器用集成式斯特林制冷机进行了数值模拟计算,在计算模型中加入了流动阻力, 同时对如此小尺寸的制冷机进行了测试。数学模型的建立完全按照真实的斯特林制冷机结构。整个制冷机分为13个控制容积,每个控制容积都建立了质量、动量和能量守恒方程。计算程序用VisualC+ +和MATLAB编写,这些基本方程通过反复迭代求解。通过本计算模型与其它经典计算模型的比较, 本模型更接近真实的斯特林制冷机工作情况,数值模拟计算的压力、和制冷功率等工作性能参数,与制冷机的实验测试的数据进行了对比。计算程序已用于新型号集成整体式制冷机的设计计算。
The integration Stifling cooler was analysed by numerical methods. The mathematical model is constructed according to a real cooler, and the flow resistance is added in the computational model. The cooler was then tested. The whole cooler is divided into 13 controlling volumes, and the mass equation, momentum equation, and energy equation were established for each volume. The computation program was written in Visual C＋ ＋ and MATLAB. These basal equations were solved by iteration. Comparing the calculating pressure and power data with the testing data, the model we constructed is more close to real Stifling cooler than other computational ones. The program has been used in new Stifling cooler design.
