Aeroelastic Analysis Using Deforming Cartesian Grids
Autor: Alexander H. Boschitsch, Glen R. Whitehouse
Publikováno v: AIAA SCITECH 2022 Forum.
Ongoing work in air-vehicle design illustrates the potential of advanced concepts to provide significant improvements in efficiency; but with their incorporation of lightweight flexible structures, such configurations may require active control syste

Autor: Andrew E. Kaufman, Pavel Danilov, Alan J. Bilanin, Alexander H. Boschitsch
Publikováno v: Volume 3: Computational Fluid Dynamics (CFD); Verification and Validation; Advanced Methods of Manufacturing (AMM) for Nuclear Reactors and Components; Decontamination, Decommissioning, and Radioactive Waste Management; Beyond Design Basis and Nuclear Safety; Risk Informed Management and Regulation.
Flow through pipe junctions produces unsteady vortex shedding processes that can generate acoustic pressures whose modal amplification contributes to structural fatigue. Such flow-induced vibration (FIV) is an enduring concern in nuclear power plants

Numerical Difficulties Computing Electrostatic Potentials Near Interfaces with the Poisson–Boltzmann Equation
Autor: Robert C. Harris, Marcia O. Fenley, Alexander H. Boschitsch
Publikováno v: Journal of Chemical Theory and Computation. 13:3945-3951
Many researchers compute surface maps of the electrostatic potential (φ) with the Poisson-Boltzmann (PB) equation to relate the structural information obtained from X-ray and NMR experiments to biomolecular functions. Here we demonstrate that the us

Investigation of grid-based vorticity-velocity large eddy simulation off-body solvers for application to overset CFD
Autor: Alexander H. Boschitsch, Glen R. Whitehouse
Publikováno v: Computers & Fluids. 225:104978
Accurately predicting unsteady wakes and vortex-dominated flows is essential to a wide range of engineering applications, including aircraft, rotorcraft, shipboard operations, bio-inspired unsteady flight and propulsion, wind turbines, and urban flow

Innovative Grid-Based Vorticity–Velocity Solver for Analysis of Vorticity-Dominated Flows
Autor: Alexander H. Boschitsch, Glen R. Whitehouse
Publikováno v: AIAA Journal. 53:1655-1669
Unsteady vorticity-dominated flows are prevalent in a wide variety of engineering applications and are particularly challenging to predict efficiently. Perhaps in no other application is this more apparent than rotorcraft, where prediction is complic
