In Canada's oil sands, bitumen is mixed with steam and the mixture is sprayed into a coker to upgrade bitumen to synthetic crude oil. The spray characteristics is one of the determining factors in the efficiently of this process. However, due to the complexity of this fluid (bitumen-steam mixture), there is very limited information on the spray characteristics of these sprays. The available studies on this type of systems, have replaced this complex mixtures with water and air mixtures or some oil and air mixtures. Bitumen-steam mixture is a highly viscous fluid with large percentage of suspended solid particles, and it is too simplistic to model it with mixture of water-air.

在加拿大的油砂中，沥青与蒸汽混合，然后将混合物喷入焦化装置，将沥青提炼成合成原油。喷雾特性是该工艺效率的决定因素之一。然而，由于这种流体(沥青-蒸汽混合物)的复杂性，关于这些喷雾的喷雾特性的信息非常有限。已有的关于这类体系的研究，已经用水和空气的混合物或一些油和空气的混合物取代了这种复杂的混合物。沥青-蒸汽混合物是一种悬浮固体颗粒所占比例较大的高粘度流体，用水-气混合物来模拟过于简单。
