Abstract :
Free convection circuits or natural circulation systems are employed in several engineering fields. In nuclear reactors, natural circulation can be used as a passive safety system or as a main heat transfer mechanism.
ork presents the results of a three-dimensional numerical analysis of a steady state rectangular natural circulation loop located at the Instituto de Pesquisas Energéticas e Nucleares/Comissمo Nacional de Energia Nuclear (IPEN/CNEN-SP). Numerical results and experimental data present in this paper are discussed and compared.
del is good enough to capture 3-D effects, such as the formation of vortex structures and swirl effects.
