The simple idea this study rests on is that one cannot be concerned by the bubbling and aromatic exhalation events in champagne tasting without being interested in the study of the flow mixing mechanisms inside the glass. Indeed, a key assumption is that a strong link of causality may exist between inherent liquid-phase flow structures due to bubble motion and the flavors exhalation process. This is the reason why, to underscore the impact of glass-shape and glass-engravement conditions on mixing flow phenomena, classical flow visualization techniques were used to capture fluid motion in traditional flutes and coupes poured with champagne. Laser tomography combined with fluorescent dyes and solid tracers have been used to give the quasi-instantaneous velocity field from which streamline patterns are deduced as well as the vorticity convection.

雕刻香槟杯中的环形涡流场景

这项研究所基于的一个简单想法是，如果不对玻璃内部流动混合机制的研究感兴趣，就不能关注香槟品尝中的冒泡和芳香呼气事件。事实上，一个关键假设是，由于气泡运动和香味呼出过程，固有液相流动结构之间可能存在很强的因果关系。这就是为什么为了强调玻璃形状和玻璃雕刻条件对混合流动现象的影响，使用经典的流动可视化技术来捕捉浇注香槟的传统长笛和双门轿跑车中的流体运动。激光断层扫描结合荧光染料和固体示踪剂已被用于提供准瞬时速度场，从中可以推断出流线模式以及涡度对流。
