Calculating Heat Generated by Piston Motion

Click For Summary

Discussion Overview

The discussion centers on calculating the heat generated by a piston moving vertically, which is slowed down by two semi-circle wedges acting as dampers. Participants explore the factors and equations relevant to this scenario, particularly in relation to friction and heat generation.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about the factors and equations necessary to calculate heat generation from a vertically moving piston with clamps.
  • Another participant suggests that the heat generated by friction can be calculated using the formula involving Force and Distance moved.
  • A later reply clarifies that the piston moves only in one plane and that the clamps apply a force that acts as a damper, but does not provide further clarity on the calculation.
  • Another participant emphasizes the need for additional parameters, such as the normal force from the clamps and the friction coefficient, to accurately determine heat generation.
  • One participant recommends searching for information on frictional heat generation for further insights.

Areas of Agreement / Disagreement

Participants express varying levels of understanding and provide different insights, but there is no consensus on the specific calculations or factors needed for determining heat generation in this context.

Contextual Notes

Participants note the importance of the normal force and friction coefficient, but these factors remain undefined in the discussion. The lack of detailed information about the system limits the ability to arrive at a conclusive calculation.

Hi,

I am testing or trying to figure out how much heat would be generated for a piston that moves up and down and has two semi-circle wedges that press against to slow down its motion.
I want know what factors and equations I can use to calculate the heat generation?
All other related topics seem to be about rotating disc.

Thanks,

You haven't really given enough information to give much of a reply, but the heat generated by friction is equal to the Force times the Distance moved.

The piston is only moving along one plane...ie vertically. The clamps are situated around the middle and squeeze against the piston as it moves up and down acting as a damper. Does that help?
 
Not really, but as said, if you have a force and a distance, you can calculate it.
 
Well, you'll need more than just a force and distance I think. I believe that you'll need the normal force acting on the piston from the "clamps". Even from there, you'll need a friction coefficient.

Google frictional heat generation, it should help you.
