A gas burner lies near the bottom of a 1~m by 1~m by 5~m high vertical channel whose walls are made of a thin sheet of insulated steel. Air at 20~$^\circ$C is forced into the bottom of the channel at 1~m/s. Mono-disperse water droplets with a diameter of $2\,000~\mu$m are introduced via a nozzle in the middle of the channel at a rate of 0.5~L/min, starting at 60~s. The water temperature is 20~\si{\degree C}, and the spray is directed at the walls with an initial velocity of 5~m/s. The water completely evaporates before it drips down to the bottom of the channel. Figure~\ref{water_evaporation_7_plot} displays the energy balance for this case. The heat release rate, \ct{HRR}, of the fire is expected to be 384~kW. The rate at which the water droplets extract energy from the system, \ct{Q_PART}, is expected to be
\be - \left( 4.189 \; \hbox{\si{kJ/(kg.K)}} \times 80 \; \hbox{K} + 2269 \; \hbox{kJ/kg} \right) \times 0.5/60 \; \hbox{kg/s} = -21.7 \; \hbox{kW} \ee
The sum of all the terms, \ct{Q_TOTAL}, is expected to be zero. The three other quantities, \ct{Q_COND}, \ct{Q_RADI}, \ct{Q_CONV}, all have plausible values, but there is no way to determine the exact values.
The sum of all the terms, \ct{Q_TOTAL}, is expected to be zero.
