In this application, surface roughness is the largest factor for fluid velocity. Yes, there are many factors that contribute to fluid velocity, but this is the dependency that we find the best improvements with.
What application and what dependency? Throwing out words without context doesn't help a discussion.
I am very familiar with various esters as I use them in formulations.
And we have an ester chemist here on BITOG that designed esters, so be careful with your claims.
Again, tri-octanoate/decanoate ester of trimethylolpropane is not unique. It is used in most Full Synthetic motor oils and Blends to improve performance in various areas. But too much ester and you affect seal swell (over-swell) which you neglected to discuss.
How can you claim any increased fluid flow with the simple addition of an ester to a motor oil? One would have to put a flow meter in the oil stream of a pressurized system with separate runs on the additized and un-additized oil. I don't see any of those tests done to support your claim.

Similar to how the medical world does not know the root causes of high blood pressure, they only know how to affect it. Some of the gains we are achieving can only be studied and documented until future technology and methods become available.
Noe of your answers are satisfactory from a tribological point of view.
Film strength has to do with the resistance of the film to shearing under pressure in surface interactions.
Molecular size and bonding is what defines esters and hydrocarbons so your answer is
Non sequitur.
The only thing you left out was Surface Tension, but you never introduced ST as a possible answer. The surface tension of an ester is only a couple of mN/m less than motor oils, so you cannot prove or claim increased flow by increasing the ester content by a small percentage of the total fluid volume.

Thanks, but you and your company are the ones making the claims in the public domain so let's keep the Q&A going here.
