Temperatures and concentrations in heated plumes
Abstract Volume concentrations and excess temperatures in plumes are shown to have the same distributions when normalized with respect to the values at the emission orifice. An expression is derived for calculating the dilution D, defined as the common ratio (source value)/ (plume value) for volume concentration or excess temperature. It is shown that volume and mass concentration distributions are not similar in general, but that the discrepancy is small beyond the jet region. Use of the ambient temperature instead of the true plume temperature to convert from mass to volume concentration will introduce an error of less than 5 per cent beyond the jet region.
