title: [Modelling of intraperitoneal chemohyperthermia: experimental study and identification of certain thermal aspects].
abstract: Intraperitoneal chemohyperthermia is more and more considered as an interesting therapeutic option in cases of some abdominal cancers, particularly of digestive origin. However, many technical aspects of this treatment remain far from being mastered, particularly the homogeneous dispatch of temperatures within the abdomen cavity. This work consists, first of all, in an experimental study, which is being carried out on a physical "prototype" of the abdomen, on which different hot fluid flows and injection conditions (configurations) are investigated. The results of this experimental study are prospected in two ways. First, an a priori thermal model is proposed, based on physical equations (heat transfer, etc.). Then a "black box" model is identified from the measured temperatures evolutions, so as to obtain a model of the "system" behaviour. Finally, the two modelling approaches are being compared, and the results converge to a simple expression of a few parameters, either physical or identified. These modelling results have helped to optimize the injection circuit and its running parameters while applied to the human treatment.
