Refractive Index Matching Measurements in an Automotive Heat Exchanger

随着混合动力汽车和电动汽车的推出，对冷却系统提出了更大的要求 在当前一代消费汽车中到位。因此，可用的时间和预算较少 用于设计和测试这些紧凑型换热器中的新型换热强化表面。这个 开发过程在很大程度上依赖于使用以下工具对其性能进行数字建模的能力 计算流体动力学(CFD)。Dana Canada Corporation目前正在寻求验证以下结果 他们对一种新的换热器设计进行了数值分析，并进行了实验速度测量。然而， 由于装置中流动的小尺度性质，再加上所得到的流场的复杂性， 没有实验数据可以用来验证数值结果。因此，该计划的主要目标是 拟议的研究是使用粒子图像测速(PIV)测量来提供验证数据和 对紧凑型热交换器流场的物理洞察。

With the introduction of hybrid and electric vehicles, larger demands have been placed on the cooling systems in place within the current generation of consumer vehicles. As a result, there is less time and budget available for the design and testing of new heat transfer enhancement surfaces in these compact heat exchangers. The development process relies heavily on the ability to numerically model their performance using tools such as Computational Fluid Dynamics (CFD). Dana Canada Corporation is currently seeking to validate the results of their numerical analysis on a new heat exchanger design with experimental velocity measurements. However, due to the small scale nature of the flow in the device, coupled with the complexity of the resulting flow field, there exists no experimental data to validate the numerical results with. Therefore, the main objective of the proposed research is to use Particle Image Velocimetry (PIV) measurements to provide validation data and insight into the physics of a compact heat-exchanger flow field.
