Large-eddy simulation of flow over a surface-mounted prism using a high-order finite-difference scheme

Aerodynamic Architectural Features to Mitigate Peak Pressures over Low-Rise Buildings

“…Pilot pressure measurements were taken on a bare model without any modifications. The pressure distribution was compared to published results by El-Okda et al, [7]. The resulting pressure distribution, Figure 5, did not match any published results.…”

“…In a study by Kwon and Kareem [6], they introduced the "Gust Front Factor" to account for transient aerodynamic effects in building codes. The effect of turbulence on the flow over surface-mounted prism using LES accompanied by velocity field measurements via PIV is examined by El-Okda et al, [7]. An experimental investigation was done by Lim et al, [8] where pressure measurements and smoke flow visualizations were done on a cube.…”

Numerical simulation and control of horseshoe vortex around an appendage–body junction

“…Dijk (2007) demonstrated the influence of Reynolds number on the formation of horseshoe vortices. El-Okda et al (2008) studied flow separation and horseshoe vortex formation, the results of which showed that primary and secondary flow separations have major effects on horseshoe vortices. Seeta Ratnam and Vengadesan (2008) explored the simulated performance of the turbulence model.…”

Numerical Simulation on the Horseshoe Vortex Formation Around the Hull-Sail Junction of Submarine

“…Vlachos [10] and El-Okda(2008) [11] studied the flow separation and formation of horseshoe vortex by experiment and calculation respectively, they pointed out that the primary flow separation and secondary flow separation had key effect on the formation of horseshoe vortex. Takayuki Tsutsui [12] studied the boundary layer thickness around the junction flow by surface oil stream pattern. Seeta [13] studied the precision of the turbulence models in the junction flow computation.…”
