The temperature increases along pipe, and the differential temperature increases with foam flow velocity decreasing.

管内温度沿管程不断升高，且流速越小温升越大；

The flow resistance of foam is affected by those parameters such as surfactant concentration, oil saturation, temperature, permeability, water and gas phase velocity, etc.

泡沫的流动阻力受泡沫剂浓度、温度、油饱和度、渗透率以及水相和气相达西流速的影响。

Injecting the mixing liquid of mud and foam achieves good effects for plastic flow property conditioning of gravel with sand.

注入泥浆和泡沫的混合液对砂卵石地层进行塑流化改善效果良好。

Some engines also contain onboard foam systems, so there will be controls to control the flow of foam concentrate into the discharges.

The boys would throw all kinds of foam boats and objects down the river and see which ones would drown and how different objects would impede the flow.
