Reservoir wettability is an important parameter for evaluating recoverable reserves and controlling fluid flow of a oil reservoir.

油藏润湿性是评估油藏可采储量，控制油藏流体流动行为的一个重要参数。

Finally, the fluid flow of the weld pool was taken into account by increasing the heat conduction coefficient at elevated temperature.

最后采用增大热传导系数的方法，考虑了熔池内流体流动对整个温度场的影响。

A three dimensional incompressible gas-liquid two-phase flow model was proposed to accurately simulate the fluid flow of casting's mould filling process.

为了更精确地模拟铸造充型过程的流动行为，建立了充型过程的三维不可压缩气。液两相流动模型。

Inside the riser pipe is a space about half a meter in diameter, large enough to hold the spinning drill pipe and bit and to allow the return flow of drilling fluid.

FORBES: The delicate art of sucking up

At that depth stopping the flow with a deadweight of drilling fluid should create few problems, once the exceedingly difficult challenge of hitting the well is met.
