I have a theoretical question regarding carbon blistering and use of a relatively viscous barrier fluid such as mineral oil. As I understand it blister patches are created on the carbon face from high shear forces due to higher viscosity fluids. In my experience, the majority of the time (not all the time) the carbon face is used as the rotary face. Is it a valid thought that by changing the stationary face to carbon, blistering could be reduced?
The basis for this thought is that the velocity profile for the stationary face is zero where as it will be however many ft/sec for the rotary face. And that based on the velocity profile of the fluid between the faces the shear forces would be reduced on the stationary face. I completely understand that the fluid film thickness between the faces is extremely small. This is just a wild thought. Feedback is appreciated.
