SUMMARY

The most effective way to measure flame temperature is by using a non-contact infrared thermometer, specifically one with a small look angle for precise readings. This method allows for accurate temperature measurements at various points in the flame, particularly just above the unburned gas. An alternative method involves creating a pinhole mask to restrict the measurement area, enabling the use of standard non-contact thermometers. Both methods are practical and cost-effective, with many infrared thermometers available for under $50.

PREREQUISITES
  • Understanding of flame dynamics and temperature gradients
  • Familiarity with non-contact infrared thermometers
  • Knowledge of measurement techniques in experimental physics
  • Basic skills in using tools for experimental setups
NEXT STEPS
  • Research different models of non-contact infrared thermometers and their specifications
  • Learn about the principles of thermal radiation and its measurement
  • Investigate the use of pinhole masks in temperature measurement
  • Explore methods for calibrating infrared thermometers for accurate readings
USEFUL FOR

This discussion is beneficial for physics students, experimental researchers, and engineers interested in flame temperature measurement techniques and methodologies.

Hypothesis: The hottest part of the flame can be found at x located just above the unburn gas.


Aim: To investigate how the temperature of a flame varies with the height of the top of the burner.





Help please getting a lot of trouble with method and how to obtain results.

For measuring flame temperature I suggest using a non-contact infrared thermometer. See:

After a quick Google search I saw many selling for less than US$ 50.00. Note: You must select one that has a small “look angle” or small angular resolution. That means it must read temperature of a very small spot in order to measure different points in a single flame. Otherwise you could rig an opaque “pinhole mask” (tinfoil?), move it slowly across the flame, and take measurements. Then you could use any old non-contact thermometer.
