Modelling pollutant dispersion in cities is challenging for air quality models as the urban obstacles have an important effect on the flow field and thus the dispersion. Computational Fluid Dynamics (CFD) models with an additional scalar dispersion transport equation are a possible way to resolve the flowfield in the urban canopy and model dispersion taking into consideration the effect of the ...

The operation of large industrial furnaces will continue to rely on hydrocarbon fuels in the near foreseeable future. Mathematical modeling and numerical simulation is expected deliver key insights implement measures further reduce pollutant emissions. These include design optimization burners, dilution oxidizer with exhaust gasses, mixing natural gas hydrogen. In this paper, we target non-prem...

Extreme waves are critical for the WEC’s development. CFD toolboxes have been widely used in simulation of extreme waves–structure interaction. However, quality mesh is a sensitive issue; large response can lead to deformation and subsequent numerical instability. In this paper, 100-year chosen from environmental contour Humboldt Bay site California, their interaction with WEC modeled using ope...
