Este trabajo se centra en la simulación del fenómeno de Limitación de Flujo a Contracorriente (CCFL) en una hot-leg experimental, crucial para la seguridad en plantas nucleares. El CCFL surge cuando el flujo de vapor, debido a las altas temperaturas del núcleo, impide la entrada adecuada de agua de refrigeración, comprometiendo el funcionamiento del reactor. Utilizando el modelo VOF-RANS y el modelo de turbulencia k-omega RNG, ambos implementados en OpenFOAM-v2206, este estudio reproduce los resultados experimentales de Issa, enfocándose en la diferencia de presión en la hot-leg para la primera región de flujo con una velocidad adimensional de líquido Jw*^0,5= 0,105. La simulación permite comparar detalladamente los regímenes de CCFL con los datos experimentales y muestra una mejora significativa en la precisión al incorporar el modelo de turbulencia de densidad variable.
