HI Rob, nas previously reported, dpm injection work, the product (h2o steam from h2-fuel and o2-oxidizer educts) is cooled down by injected water droplets. nBut, I have another issue, the water droplets doesn't evaporate into water-vapour, somehow droplets dissociate in reactor therefore, after h2o injection a lot of free h2.nThe idea behind this cfd is to oxidize h2 exactly stochiometric to get h2o hot steam which will be cooled with saturated steam (liquid water-stem 220bar 180°C) down to required temperature, in this case around 530°C at 40 bar.nnI guess, the solver set-up is not correct? nHoppe you can help. nThanksnn
