Numerical Modeling of Coupled VSTOL-Ship Airwake Flowfields

Abstract

Validation of CRUNCH CFD® for problems of relevance to modeling coupled VSTOL-Ship Airwake flow fields is presented. The basic numerical framework consists of an edge based multi-element unstructured Navier-Stokes solver. The governing equations are solved using an upwind biased MUSCL scheme and an implicit scheme is used for time marching. Validation of the spatial and temporal aspects of the numerical framework are presented here, with a special emphasis on bluff body shedding problems as these are of particular relevance to the VSTOL-Ship airwake problem. Results from simulations of several unit problems are presented.

The Current Status of Unsteady CFD Approaches for Aerodynamic Flow Control

“…Moore's law predicts that increases in computer hardware will yield O10 1 improvements. All these e ects can be combined in a multiplicative sense to yield potential improvements of O10 4 . Improvements of this magnitude would allow us to do 3-D optimization studies based on DES turbulence models, including uid actuator design and resonance, and actuator placement and coupling studies.…”

“…The composite models go by di erent names and involve di erent turbulence models for the RANS and LES regions and di erent switching functions to shift between the RANS and LES regions. Batten, Goldberg, and Chakravarthy 18 proposed limited Navier Stokes; Zhang, Bachman, and Fasel 148 developed their ow simulation methodology; Arunajatesan, Shipman, and Sinha 4 developed the hybrid RANS-LES. However, the rst and perhaps the most thoroughly tested of these composite models has been the detached eddy simulation DES model of Spalart.…”

Computational Fluid Dynamics Simulations of Ship Airwake

“…The atmospheric boundary layer was modelled as a farstream inflow/outflow boundary condition while considering enough grid resolution over the ocean surface plane, and improved the comparisons of the predictions with the full-scale experimental data. Recently, Arunajatesan et al [40,41] have conducted some preliminary steady/unsteady calculations of the LHA ship airwake using MILES approach.…”

Preparation of Nano-Composited Catalyst from the Bulk Intermetallic Compound AuZr3 with Hydrogen Absorption

“…Nevertheless, most of the current methods to prepare gold catalysts are not practically easy [8,9]. To overcome this hurdle, gold-containing alloys and IMCs have been used as useful precursors to prepare gold catalysts [10][11][12][13].…”
