Investigation of Grid Adaptation to Reduce Computational Efforts for a 2-D Hydrogen-Fueled Dual-Mode Scramjet
… flow solver with various computational grids. Results are obtained for fuel-off, fuel-on non-reacting, and fuel-on reacting cases at different equivalence ratios. A one-step global chemical kinetics hydrogen-air model is used in conjunction with the eddy-dissipation model. Coarse, medium …

Computational modeling of wind turbine wake interactions
… (LES) with a dynamic Smagorinsky-Lilly sub-grid scale (SGS) model. The simulations showed the grid refinement to be inadequate for LES studies. The RANS closure schemes did not indicate a dominant model. However, relevant literature on separating flows has shown the k-ω SST model to be …

CFD Modeling and Simulation of Natural Circulation in Helium- Cooled Very High Temperature Reactors
… heating configuration. Mesh sensitivity and grid independence studies were performed to ensure numerical stability and solution accuracy, with fine resolution applied near heated surfaces. Helium thermophysical properties were implemented using pressure and temperature-dependent polynomial …

Computational Fluid Dynamic and Rotordynamic Study on the Labyrinth Seal
… the discretization error, a systematical grid study was conducted including grid independence studies and discretization error estimations. Some of the results were compared with previous bulk-flow or experimental results to validate the numerical model and method. The fluid field in the …

Development of Improved Mathematical Models for the Design and Control of Gas-Fired Furnaces
… CFD simulations, which were tested for grid independence and compared where possible to data from closely related problems, were capable of simulating the furnace flow and mixing patterns for a variety of burner characteristics.<br/><br/>The zone models were then used to investigate both …

Computational Analysis of Straight and Maneuvering Bat Flight Aerodynamics
… the computational model was preformed through a grid independence study as well as careful evaluation of other relevant simulation parameters. Verification of the model was performed by comparing simulated aerodynamic loads to the expected loads based on the observed flight trajectories. …
