Talk:Magnetorheological fluid

Anisentropic?

What is "anisentropic" ?

Yeah, I messed that up, I meant "anisotropic", which I think someone has changed. What has happened to the pictures and equations???! WillBecker 14:38, 22 January 2007 (UTC)

Why were the pics and eqns removed?

In fact I will put all the pictures and eqns back in unless anyone has got a decent reason why they took em out? I can't see how it is helping the article. WillBecker 14:43, 22 January 2007 (UTC)

I think at the very least the modes diagrams and perhaps the typical shear stress vs. shear rate graph with the Bingham Plastic fit lines and the apparent yield stress labeled should be readded, as well as equations for the Bingham model and a short explaination of why we can use such a simple model. It would also be nice to see the more precise fluid models (e.g. Phillip's equations and Carlson's equations) listed and explained, but that may be more advanced than necessary for most readers. But then again as long as the advanced models are separated clearly and cleanly from the basic information then I think it should be included. Also I think a distinction needs to be made between a ferrofluid and a magnetorheological fluid, with necessary links. Josh.karli 03:11, 19 March 2007 (UTC)

Practical potential

Just a thought The potential in this and Ferro-fluid technology is so astronomical that it needs 2 be brought to the attention of more than just the intellectual. Andy S. Sep. 4 2008 P.S. I would ike to see the equations for better understanding as i do not feel i personaly have fully understood it. —Preceding unsigned comment added by 76.111.81.247 (talk) 02:12, 5 September 2008 (UTC)

Disputed sentences

An IP editor deleted most of this paragraph claiming it was not in the reference:

When the fluid is contained between two poles (typically of separation 0.5–2 mm in the majority of devices), the resulting chains of particles restrict the movement of the fluid, perpendicular to the direction of flux, effectively increasing its viscosity. Importantly, mechanical properties of the fluid in its “on” state are anisotropic. Thus in designing a magnetorheological (or MR) device, it is crucial to ensure that the lines of flux are perpendicular to the direction of the motion to be restricted.

This may not be in the reference (and the tone may not be quite "encyclopedic"), but it does not sound obviously incorrect. I am pasting the text here, so that some other editor may perhaps confirm and/or provide a ref. Bona-fide but defective contributions should be improved upon, not just deleted. --Jorge Stolfi (talk) 01:23, 19 February 2013 (UTC)
