Hi all!
I wish to calculate the heat transfer from a pipe/equipment wall heated by fire, into the gas inside the pipe/equipment. The heat input to -and temperature rise of the wall is calculated with standard radiation and convection equations. Compared to liquid filled sections the heat input to the gas will be small due to much lower heat transfer coefficient and thermal mass of the gas. My initial thought was to use a heat transfer coefficient between the gas and steel wall. However I am unsure how this is calculated or where it can be found and whether other factors should be included in the calculations.
I am preparing a spreadsheet in Hysys simulation tool for the calculations so I have the resources of Hysys available for the calculations if that can be of help.
Any advice on this subject or suggestions for good relevant resources would be greatly appreciated.
Thanks!
