Gas temperature fails for small HRR #132

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
For very small HRR, gas temperature calculations are much higher than layer 
temperatures fat away from the fire. This looks like an error in the logic 
deciding when the point of interest is within the flames.

This occurs when the calculated flame height from Heskestad's correlation is 
negative.  Fix is to prevent it from going negative with a check on its value 
in get_gas_temp

Fixed in r1954. Simple set minimum flame height to a value of 0.1 m in 
get_plume_temperatureandvelocity
