Scale Effect of Aerodynamic Characteristics in Evacuated Tube Maglev Transport

  • 摘要:

    为了探究管道列车的尺度对波系、尾涡以及气动载荷的影响,基于CFD软件建立三种模型尺度(1∶1,1∶5和1∶10),同时考虑两种悬浮间隙关系(车轨相对间隙不变和绝对悬浮高度不变)的模型;采用改进的延迟分离涡模拟(IDDES)湍流模型和重叠网格技术模拟了列车在管道动态运动,并用风洞试验数据验证了数值方法和网格策略的合理性. 研究结果表明:列车尺度(雷诺数)增大,车前活塞区域变长,尾流扰动区范围缩短;雷诺数对近尾流区的涡对演化影响较小,但在远尾流区,随着列车尺度减小,涡对脉动变强,涡对强度的差异导致了车后正激波形态的差异;列车表面最大正压值和最大负压值均随着列车尺度增大而增大,悬浮间隙对最大正压值影响较小,但与最大负压值成正相关关系;尺度效应从压差阻力和摩擦阻力两方面共同影响气动阻力,整车摩擦阻力和头、中间车的压差阻力与雷诺数正相关,但是尾车压差阻力受附着激波的强度影响恰恰相反;列车尺度和悬浮高度均对升力影响较大. 相对于全尺寸模型,1∶10模型(悬浮高度20 mm)的最大正压值减小3.82%,最大负压值增大3.94%,整车总阻力增大8.64%,头车升力减小101.56%,尾车升力增大15.88%.
