An evaluation of the Computational Fluid Dynamics (CFD) sub-models for in-cylinder diesel engine combustion and emission simulations was conducted using an integrated numerical model from commercial CFD software FLUENT 6.3.26. As these simulations are sensitive to user-defined empirical parameters, the main aim of this investigation is to obtain an adjusted set of model parameters in order to achieve...
Some of the primary concerns in integrating domestic scale renewable energy systems in city buildings is siting optimization and size scaling of domestic wind turbine models on building roof tops discounting the zone of wake influence. This is a Case study scenario of a regional wind resources distributions and predominant wind directions computation for CFD modeling to identify laminar and turbulent...
This paper provides a comparison between calculating hydrodynamic coefficients based on engineering publications or by using computational fluid dynamics [CFD]. The CFD examines various computational codes and compares how the various turbulence models examined performed, as well as the effect of grid refinement on the resultant hydrodynamic coefficients. Using accurately derived hydrodynamic coefficients,...
