Exhaust gas properties
Exhaust gas properties
(OP)
I'm working on a calculation of diesel exhaust system back pressure and was wondering if there were any values for gas densities and viscosity? Or are the properties for air at exhaust temperatures close enough?





RE: Exhaust gas properties
When considering Diesel engine operation, an ideal cycle approach might be sufficient to get you initial density values.
Therefore, I would suggest that you use ideal gas state equation when calculating density values:
pv = RT
p/density = RT
Go with air properties -- ignore the impact of fuel on the working fluid (combustion products).

Hi gcomyn, this site has been widely advised in the Eng-Tips Forums and, certainly, is a good one. http://www.hrsgdesign.com/design0.htm
When open, ---> "Process" ---> Thermal properties of flue gas.
Good luck !

The info is used by turbine engine engineers, and my guess is that you should look for turbine engine data resources to get similar data.
