  • Torsional current - meter for channels 
    Zarea, Stefan; Rojas-Solorzano, L. (1997 ASME Fluids Engineering Division Summer Meeting, June 22-26, 1997-06-22)
    The main objective of this paper is to present the results of the experimental investigation of a Zarea-type torsional velocity-meter. For this, a torsional meter was designed, built and tested in the laboratory. The current ...
  • Transient Two-Phase-Flow Model for Predicting Column Formation in Intermittent Gas Lift Systems 
    Sandoval, Sarita; Rojas-Solorzano, L.; Gasbarri, Sandro (SPE Latin American and Caribbean Petroleum Engineering Conference, Rio de Janeiro, Brazil, 20 – 23 June 2005, 2005-06-20)
    The major objective of this work is to generate a mathematical model, allowing the prediction of mixture density, liquid holdup, the pressure gradient in the pipe and the real column size. This is useful for optimizing ...
  • 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, ...
  • Two-fluid Mixing Enhancement by Using a Static Turbulence Generator 
    Ortega, P.; McGrath, G.; Rojas-Solorzano, L. (SPE International Thermal Operations and Heavy Oil Symposuim, Porlamar, Venezuela, 12–17 March 2001., 2001-03-12)
    The numerical simulation of a static T-type mixer for turbulent mixing of miscible liquids is reported. The simulation was carried out using CFX, a commercial computational fluid dynamic simulator. The effect of mixing ...
  • 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 ...
