Aspects of POD-based wall-layer modeling for the variational multiscale methods

Stabilisation Parameter Determination for the Stokes Equations

Parameters for SGS models within the variational multiscale method for the Stokes equations are determined using two different methods. Both linear and nonlinear models are considered. Firstly, optimal parameters are found using a goal-oriented model-constrained technique minimising L2 error. Secondly, parameters are obtained using the...

A Fractionated Spacecraft System Assessment Tool Based on Lifecycle Simulation Under Uncertainty

To comprehensively assess fractionated spacecraft, an assessment tool is developed based on lifecycle simulation under uncertainty driven by modular evolutionary stochastic models. First, fractionated spacecraft nomenclature and architecture are clarified, and assessment criteria are analyzed. The mean and standard deviation of risk adjusted...
