Calculating heat transmission loss in a thick glass
Posted on 2009-04-04
Do anybody here knows, if and how much and how quick a thick tempered (60 degrees celcius) glass (85mm) of size 500mm * 500mm looses it temperature?
What I want to know, is the temperature profile "out-of-plane" inside the 50-100mm thick glass and related to time.
The glass is surrounded by air of ambient temperature (20 degrees celcius).
I know there are several programs out there, who could answer this question, such as COMSOL 3.5, ANSYS Multiphysics, NAFEMS etc. But I don't have acces to these fancy software packages.
Did anyone here made some calculations related to the above?
How much heat energy/temperature do a thick window as described above loose within 5, 10 and 15 minutes surrounded by ambient temperature?
Thanks in advance
