Thermodynamics: Modelling the internal environment of a tent

Click For Summary
SUMMARY

This discussion focuses on modeling the internal temperature profile of a tent, specifically under conditions where two individuals generate approximately 160W of heat and solar gain contributes around 850W/m². The outside air temperature is estimated at 10°C, with considerations for heat loss from the tent. The user seeks guidance on relevant thermodynamic principles, particularly questioning the applicability of 'Adiabatic Mixing of Airstreams' due to ongoing heat loss from the tent.

PREREQUISITES
  • Understanding of basic thermodynamics principles
  • Knowledge of heat transfer mechanisms
  • Familiarity with energy balance equations
  • Experience with modeling environmental conditions
NEXT STEPS
  • Research 'Heat Transfer in Enclosed Spaces' to understand temperature dynamics
  • Explore 'Energy Balance Models' for environmental modeling
  • Investigate 'Thermal Conductivity of Tent Materials' for accurate heat loss calculations
  • Learn about 'Ventilation Strategies in Tents' to optimize cooling with fans
USEFUL FOR

This discussion is beneficial for environmental engineers, outdoor enthusiasts, and anyone involved in thermal modeling or designing camping equipment for improved comfort in varying weather conditions.

Hi,

I am trying to model the temperature profile of the inside of a tent, with a view to introducing a fan which can suck outside air, to inside the tent, to cool it down on a hot sunny summer morning.

I thought I would start by just trying to model the interior of a tent in these conditions without the fan.
I'm assuming 2 people inside giving of a total of about 160W of heat. I would like to assime solar gain from the sun providing approx 850W/m^2 of heat to the side of the tent. The outside air temp will be about 10 Deg C, I also have some experimental data on the rate of heat loss from my 'typical' tent.

What area of thermodynamics should I look into to start my model? It has been suggested to look at 'Adiabatic Mixing of Airstreams' but it seem to me this is not an adiabatic process as heat is being lost from the tent all the time.

Does anyone have any suggestions to get me going?

Thanks

Also look into the green house gases.. once of the 2 individuals decides to release x amount of gas, there will be local warming followed by reduced oxygen content
