Viscous damping acting on rotating disk

AI Thread Summary
To calculate the torque and viscous damping coefficient on a rotating metal disk in an oil sump, one should explore fluid mechanics literature, particularly regarding torque on a finite disk in a viscous fluid. This problem may not be commonly addressed in standard textbooks or online resources. The discussion suggests searching for terms like "viscous drag on rotating disc" to find relevant studies. The original poster expresses a desire for guidance due to a lack of mechanical engineering expertise. Finding the right keywords is crucial for locating useful information on this topic.

I am looking for a way to calculate the torque, hence the viscous damping coefficient per T = c*w, acting on a rotating metal disk in an oil sump. How can I go about it? Thanks!

PS. I am not a ME so please forgive my ignorance.

You may be able to find something in the fluid mechanics literature about the torque on a finite disk rotating in an infinite ocean of viscous fluid. I don't think it is something that you are going to find in everyday textbooks, and probably not on line. I assume you are not interested in setting up the problem and solving it yourself or using CFD software.

Thank you for the reply. Well I would be interested in that but I don't have the necessary skills to do so. I was hoping to find an answer online because I thought it would be a common fluid dynamics problem in the ME world. I could search the literature but I would need help with choosing the right keywords.
 
Try viscous drag on rotating disc.
 

Thread 'Bubble formation in 4 mm gap vessel'

How did you find PF?: Via Google search Hi, I have a vessel I 3D printed to investigate single bubble rise. The vessel has a 4 mm gap separated by acrylic panels. This is essentially my viewing chamber where I can record the bubble motion. The vessel is open to atmosphere. The bubble generation mechanism is composed of a syringe pump and glass capillary tube (Internal Diameter of 0.45 mm). I connect a 1/4” air line hose from the syringe to the capillary The bubble is formed at the tip...

Thread 'Calculate minimum RPM to self-balance a CMG on two legs'

Here is a photo of a rough drawing of my apparatus that I have built many times and works. I would like to have a formula to give me the RPM necessary for the gyroscope to balance itself on the two legs (screws). I asked Claude to give me a formula and it gave me the following: Let me calculate the required RPM foreffective stabilization. I'll use the principles of gyroscopicprecession and the moment of inertia. First, let's calculate the keyparameters: 1. Moment of inertia of...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
