Different thermal boundary conditions affected the flow field, then affected the heat transfer, rotation was the main reason of the affection, viscous heating and buoyancy were two important factors.

转动是热边界条件影响左右盘壁面换热系数的主要原因，粘性热和浮升力也是导致热边界条件对换热系数有影响的两个重要因素。

Viscous flow patterns are set up in the motor, increasing heat transfer to the propellant surface through greater mass transfer.

粘性流场的模式成立，在电机，增加传热推进剂表面通过更大的传质。

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。
