Non-newtonian fluid Definition and 12 Threads

I am working on a project to dry liquid digestates (residue from the fermentation process of biogas plants). The liquid digestate has a dry matter (DM) content of about 3%. The digestate is primarily made up of animal manure and maize silage. It is a non-Newtonian fluid having a viscosity of 4...

Hi guys, I came upon a definition of Non Newtonian fluid that is any fluid which doesn't deform linearly with increasing stress. But then if you think about fluids, pretty much every fluid acts like this, depending on whether you're actually capable of generating enough force to see it happen...

Here is some background to the problem (in a stirred tank): "With yield stress non-Newtonian (viscoplastic) fluids, it is possible to generate an agitated volume around the impeller, defined as a cavern, surrounded by a stagnant region where the shear stress is insufficient to overcome the...

I am intrigued by the diversity of Non-Newtonian fluids and need to ask a question. Can anyone provide me with a breakdown of what goes on at the quantum level as the Non-Newtonian fluid bounces up and down on top of the speaker in the video I have embedded. What I would like to know is...

How does one setup the stress tensor for a non-Newtonian fluid? I know that for any fluid the normals should be the pressure and for a power law fluid the shear stress in the direction of flow is related by K(du/dy)^n. Does this mean that all other components are 0 for a symmetric pipe or...

So everyone has made non-Newtonian fluid at some point in their lives (when you mix corn starch and water and get that awesome liquid/solid) well in one of my classes last semester we were asked to think of ways to aid in shielding from radiation and MMOD's (Micro Meteoroids and Orbital Debris)...

Hi, What is the molecular-level mechanism of shear-thickening of oobleck (cornstarch-water paste)?

This is my first posting on this forum. I apologize if this is the wrong place. My friend is trying the experiment where corn starch is placed on a speaker at low frequencies and forms strange shapes. There are videos on youtube but I cannot add links yet. It's for our physics class as a final...

I need to make a simple model of a strain-hardening fluid flow, basically to find shear force on a wall. I'm looking at the Ostwald model http://www.answers.com/topic/power-law-fluid but I can't find any values for "K" for any material. I don't really care too much what material I'm looking...

Here is the problem. I drop a pole (say length L, mass M, radius R) on a non-Newtonian fluid (corn starch and water) with impact velocity v. The density and viscosity of the oobleck is known, and I know the dimensions of the oobleck container (a square box of length S filled up to height H...

I would like to calculate pressure drop rate across a valve,... Material is a "non-soluble" polymer melt dispersed in water...When the solution is released at high temperature from a valve I would like to calculate pressure drop rate... Question is should we be using non-Newtonian...

Hi guys, to the point, I watched this video in youtube about how the guy put non-Newtonian fluid on a speaker and when they turn the speaker on, the fluid just went wild. as I'm still a high school student, i don't really understand this phenomenon, and I'm interested to know what will happen...
