Complex applications in fluid dynamics research often require more highly resolved velocity data than direct measurements or simulations provide. The advent of stereo PIV and PCMR techniques has advanced the state-of-the-art in flow velocity measurement, but 3D spatial resolution remains limited. Here a new technique is proposed for velocity data interpolation to address this problem. The new method performs with higher quality than competing solutions from the literature in terms of accurately interpolating velocities, maintaining fluid structure and domain boundaries, and preserving coherent structures.
流体动力学研究中的复杂应用通常需要比直接测量或模拟所提供的更高分辨率的速度数据。立体粒子图像测速技术（stereo PIV）和相位编码磁共振成像技术（PCMR）的出现推动了流速测量技术的发展，但三维空间分辨率仍然有限。本文提出了一种新的速度数据插值技术来解决这一问题。在精确插值速度、保持流体结构和域边界以及保留相干结构方面，新方法比文献中的其他竞争解决方案具有更高的性能。
