Résumé

A one-dimensional numerical model is developed for motion and heat transfer in a three-phase, spray-column, direct contact heat exchanger. General equations are defined for distance up the column using a physically-based model for the local heat transfer. A new formulation is given for a mixed, time-averaged temperature that may be representative of measurements taken with temperature transducers in direct contact heat exchangers. Results are compared to experimental data found from the operation of a 0.6 m dia, 6 m high spray column heat exchanger using pentane and water. Good agreement is shown between the predictions and the data.
