The present work reports an numerical study of a turbulent natural convection flow resulting from the interaction of a thermal plume with a thermosiphon flow. in this paper we expose results of the numerical study related to the heating source position. We study particularly the effects of the vertical source canal spacing on the flow structure. A comparative study is presented for different configurations. This study is based on CFD fluent code results concerning the average field. These results are compared with experimental results.
