OLMO-VELAZQUEZ, Annamaris et al. Study and modelation for low reynolds value of two phases flow liquid-gas. Ingeniería Mecánica [online]. 2015, vol.18, n.1, pp.1-11. ISSN 1815-5944.

The study of simultaneous flow of liquid and gas over a conduit, is two phases flow combinations more complex that exist. For the study we select fluid (glycerin in solution with water (80 %) and industrial gel) that establish flow models necessary for the investigation the desired systems. And is obtained from physical-mathematical analysis of obtained results made experiment for different configurations, a theorys experimental model have evaluate the drag coefficient and force acting on only bubble and train bubbles in job regimen for Reynolds value less and equal to 15. In the present study was performed computational modeling of different patterns, validated with experimental results. Simulations and results obtained for visualizing and analyzing the actual system behavior. These models are ready for been used for other configurations in future studies.

Palavras-chave : two phases flow; Reynold´s number; only bubble; train of bubble; drag coefficient; drag forces.
