• Computational fluid dynamics - lustres and shadows.

  Publikacja

  • J. Sawicki

  - Rok 2014

  The paper is devoted to the different aspects of CFD. The advantages of this concept are evident and obvious; powerfuk and effective tools bring this technology closer to the quantifiable world. However, certain weaknesses in this structure are apparent. Sometimes, a simplistic tendency towards simplifications and facilitations may degenerate and lead to negative behaviours and signs. These have not been serious up to date, but...

  The maxillary sinus aeration using the computational fluid dynamics (CFD) method based on individual adult patients’ computed tomography (CT) scans were analyzed. The analysis was based on CT images of 4 patients: one with normal nose anatomy and three with nasal septal deviation (NSD) and concha bullosa (CB). The CFD simulation was performed using the Reynolds-Average Simulation approach and turbulence closure based on linear...

• Computational Fluid Dynamics Simulation of Gas–Liquid Multiphase Flow in T-junction for CO2 Separation

  Publikacja

  • S. Wrzesień
  • P. Madejski
  • P. Ziółkowski

  - Prace Naukowe Wydziału Architektury Politechniki Wrocławskiej - Rok 2020

  The article presents the results of a computational fluid dynamics (CFD) analysis of gas-liquid multiphase flow. The simulation was conducted using CFD code and the Euler–Euler approach. The presented study relates to the non–reactive, steady-state, turbulent flow of water and carbon dioxide mixture in a 3D pipe. Separation phenomenon between phases is observed. The solution was obtained using a mixture model. Different values...

• Aerodynamic shape optimization by variable-fidelity computational fluid dynamics models: a review of recent progress

  Publikacja

  • L. Leifsson
  • S. Kozieł

  - Journal of Computational Science - Rok 2015

  A brief review of some recent variable-fidelity aerodynamic shape optimization methods is presented.We discuss three techniques that—by exploiting information embedded in low-fidelity computationalfluid dynamics (CFD) models—are able to yield a satisfactory design at a low computational cost, usu-ally corresponding to a few evaluations of the original, high-fidelity CFD model to be optimized. Thespecific techniques considered here...

  • J. Mąkinia
  • K. Czerwionka
  • M. Swinarski

  - WATER ENVIRONMENT RESEARCH - Rok 2009

  The aim of this study was to use computational fluid dynamics for predicting the behavior of reactive pollutants (ammonia and phosphate) in the aerobic zone of the bioreactor located at the Wschod wastewater treatment plant in Gdansk, Poland. The one-dimensional advection-dispersion equation was combined with simple biokinetic models incorporating the Monod-type expressions as source terms for the two pollutants. The problem was...

• Optimization of hydrodynamic vortex separator for removal of sand particles from storm water by computational fluid dynamics

  Publikacja

  • M. Mahaveer
  • X. You

  - Desalination and Water Treatment - Rok 2021

  Storm water treatment has been gradually acknowledged for the removal of pollutants from urban areas using the hydro cyclone separation technique. The separation efficiency of the hydrodynamic vortex separator (HDVS) is a complex phenomenon. With the aim enhance the separation potency of HDVS for storm runoff to get rid of sand particles, the HDVS with different structural configurations was studied by computational fluid dynamics....
