Canada has traditionally been at the forefront of the metals industry in supplying technology and value-added products. It ranks third in production of aluminum and nickel and is a major producer of other metals such as copper and steel. In most of the metal production and refining processes, gas injection into liquid baths at high temperature is a common practice. The intention of this operation is to thermally/chemically homogenize the bath and/or introduce reactive gasses into the liquid for refining of the melt. Understanding the intensity of the mixing of the liquid bath is of crucial importance in increasing productivity, reducing production costs, and lowering environmental emissions. However, because of the hostile environment in the metallurgical furnaces, it is extremely difficult to obtain information on details of the process in the actual operation. Instead, laboratory scale simulation of the process at low temperature has frequently been employed to understand the behavior of the actual systems.

加拿大在提供技术和增值产品方面历来处于金属行业的前沿。它的铝和镍产量排名第三，也是铜和钢等其他金属的主要生产国。在大多数金属生产和精炼过程中，在高温下将气体注入液体浴中是一种常见的做法。该操作的目的是对熔池进行热/化学均化和/或将反应性气体引入液体中以精炼熔体。了解液体浴的混合强度对于提高生产率、降低生产成本和减少环境排放至关重要。然而，由于冶金炉内环境恶劣，在实际操作中获取工艺细节信息极其困难。相反，经常采用实验室规模的低温过程模拟来了解实际系统的行为。
