3D CFD Modeling Investigation of Potential Vortex Formation at the Intakes of Caruachi Powerhouse

Marcano, A.; Rojas-Solorzano, L.; Reyes, M. (INTERNATIONAL CONFERENCE ONHYDRAULICS OF DAMS AND RIVER STRUCTURES, TEHRAN, IRAN; 04/2004, 2004-04)

In this paper, the 3-D CFD simulation of the free-surface flow approaching the intakes of Caruachi Powerhouse is presented. The aim of the investigation is to determine whether or not vortex structures are likely to ...
CFD modeling of slurry flows in horizontal pipes

Hernández, Franz H.; Blanco, Armando J.; Rojas-Solorzano, L. (Proceedings of FEDSM2008 8th Symposium on Applications in Computational Fluid Dynamics August 17-20, Jacksonville, FL, 2008-08-17)

Liquid-solid two-phase flows are found in numerous operations in the chemical, petroleum, pharmaceutical and many other industries. In numerous cases, the mixture or slurry that flows is composed by a suspension of solid ...
Numerical study of smoke propagation in a simulated fire in a wagon within a subway tunnel

Vittori, Felipe; Rojas-Solorzano, L.; Blanco, Armando J.; Urbina, Rafael (Proceedings of FEDSM2008 2008 ASME Fluids Engineering Conference August 10-14, 2008 Jacksonville, Florida USA, 2008-08-10)

This work deals with the numerical (CFD) analysis of the smoke propagation during fires within closed environments. It is evaluated the capacity of the emergency ventilation system in controlling the smoke propagation and ...
Numerical study of turbulence models in the computation of blood flow in cannulas

Salazar, Felix A.; Rojas-Solorzano, L.; Antaki, James F. (Proceedings of FEDSM2008 2008 ASME Fluids Engineering Conference August 10-14, 2008, Jacksonville, FL, USA, 2008-08-10)

In recent years, CFD has become an increasingly used tool in the design of blood-based devices. However, the estimation of red blood cells damage (hemolysis) remains a very important challenge due to the complex rheology ...
Two-dimensional numerical simulation of saltating particles using granular kinetic theory

Marval, Juan P.; Rojas-Solorzano, L. (Proceedings of FEDSM2007 2007 ASME/JSME Fluids Engineering Division Summer Meeting July 30-August 2, 2007, San Diego, California, USA, 2007-06-30)

Most granular flows at environmental conditions are unsteady and exhibit a complex physical behavior. Dune formation and migration in the desert are controlled not only by the flow of saltating particles over the sand bed, ...
Verification and validation of computational fluid dynamics simulations of compound channel

Filonovich, M. S.; Azevedo, R.; Rojas-Solorzano, L.; Leal, J. B. (2010)

In this study the verification and validation of a 2nd order turbulence closure model is performed for an experimental compound channel flow, where the velocity field was measured by a Laser Doppler Velocimeter. Detailed ...
