Youger folks, interested in the problem, should read the paper by Andrade and Hart: "Effect of an electric field on the viscosity of liquids' 3". Proceedengs Royal Society, 1954. They studied effect of alterneiting alectric field on viscosiyu of polar liquids, effect dissapeared at 500 Hz -1 khz, relatively low frequencies. That indicate that liquid is clastered, not behaving like individual molecules. More experimental data should be collected, theoretical explanation should be provided. Such experiments will constitute visco-electric spectroskopy, helping scientists in better understanding of liquid state. We just need 1exprimental Physicist to get interested, in starting the project. 

More on the subject of Viscosity Icrease of Polar Liquids in an Electric Field can be found in experimental workks of Abdrade, FRS. and Dodd, 1946, 1951, Proceedings of Royal Society. PDF files are not available from this Journal, so, I post again what is available.

Dear Professor Alexander J. Babchin

Thank you very much for asking this question on RG. Really, I am trying to do some new things on the topic of viscosity.

Thanks dear Alex for the two interesting papers.The second paper lets last pages missing. Do you think you could send them again.

Many thanks and regards

Hanno, Mohammad, I checked the file of the second paper in my computer, all pages are in place. So, I try to upload the file again. Thanks for your interest.

Mohammad, you have all needed qualification to run these experiments as frequency dependent. Then, I can support your data theoretically. I looked at your profile, very impressive, Associated Professor on the way to Full Professor. I wonder what's wrong with your local educational system. 

Hallo Alex, thanks for the second upload.

Sure, Hanno, I heard about this unique paper of 1936, but there was no any trace on Internet until very recently, I got it in October,, this year. 

Most interesting is that a polar Newtonian liquid, like acetone, becames a shear rate dependent Rheological body, in the sense of viscosity, when submitted into electric field. The authors of theoretical paper of 1976 were under illusion that they are first to pin down this phenomenon for liquids, but they were mistaken. Experimental evidence of the same was published 40 years earlier. But, without Internet, it was next to impossible to find this piece of information. 

Dear Alex,

I like your historical papers a lot. Take someone´s illusions some times. And written well.

Thanks Alexander for asking this question and uploading two supporting documents. It is an interesting field to work.

Thanks, fellows for your support. That was the hardest project in my life time.

Thanks Alex. It is interesting to see the process and good explanation. 

Thanks, Hashem. I am very keen that some Physicist on RG will continue experimental work in this direction. Mohammad from KSA fits the bill perfectly. I only don't understand why he is still Assistant Professor , having full Professor Credentials. 

Other folks also may be interested. I did one work with Lijo Francis over Internet. For folks from Arab Countries my association is Alberta Research Council, Edmonton, Canada. I retiered in 2009 from there, but still keep position as Emeritus Distinguished Scientist, So, no complications with my current location.  Political stupidity can be simply removed from cooperation. My email address is Russian based   [email protected]   So, any one interested in cooperation may wish to contact me by email. 

Alex and great folks altogether, I would like to extend the question regarding electric fields and viscosity as follows. We differentiate between Newtonian and non-Newtonian fluids where viscosity is either constant or variable in dependence of certain external parameters, e.g. of mean-flow shear, if the fluid is a tall in motion. In that case we differentiate between so-called shear-thickening and shear-thinning fluids. In the former case viscosity increases monotonously with increasing shear, in the latter case vice versa. I guess that all known cases where viscosity scales with electric field or frequency etc. give only a thickening behavior, correct? Or do you know of a thinning case?

@Helmut. Viscosity of Polar Liquids in an Electric Fiels  decreases with shear rate increase.
