In the following soak (shut-in) phase, the well is shut in for days to allow the heat to dissipate in the reservoir and the heavy oil to heat up and become less viscous.
在接着的浸泡(关井)阶段，关井数天，使热量在储层中消散并使重油加热和降粘。

The firing of enamel frit is a process of "Liquid-phase Sintering". Its mass transfer is based on the viscous flow of the melt.
搪瓷釉的烧成过程是一种“液相烧结”过程，其传质有赖于熔体的粘性流动。

For the breaking up and atomization of viscous liquid jet from the air-blast nozzles is a complicated multi-parameter two-phase flow problem, it is hard to forecast the size of the droplet exactly.
