ASWING 5.99 Technical Description — Steady Formulation
نویسنده
چکیده
ASWING is a program for the prediction of static and quasi-static loads and deformations of aircraft with flexible high aspect ratio surfaces and fuselage beams. The key features of the overall structural/aerodynamic model are sketched in Figure 1. A fully nonlinear Bernoulli-Euler beam representation is used for all the surface and fuselage structures, and an enhanced lifting-line representation is used to model the aerodynamic surface characteristics. The lifting-line model employs wind-aligned trailing vorticity, a Prandtl-Glauert compressibility transformation, and local-stall lift coefficient limiting to economically predict extreme flight situations with reasonable accuracy.

Comparison of three different numerical schemes for 2D steady incompressible lid-driven cavity flow
In this study, a numerical solution of 2D steady incompressible lid-driven cavity flow is presented. Three different numerical schemes were employed to make a comparison on the practicality of the methods. An alternating direction implicit scheme for the vorticity-stream function formulation, explicit and implicit schemes for the primitive variable formulation of governing Navier-Stokes equatio...
متن کاملThree faces of the second law. I. Master equation formulation.
We propose a formulation of stochastic thermodynamics for systems subjected to nonequilibrium constraints (i.e. broken detailed balance at steady state) and furthermore driven by external time-dependent forces. A splitting of the second law occurs in this description leading to three second-law-like relations. The general results are illustrated on specific solvable models. The present paper us...
متن کاملThe Approach of Convergence to Stationary State of Multi Server Queue with Balking (TECHNICAL NOTE)
This investigation deals with multi server queue with balking. The customers arrive in poisson fashion and independent of time, under the assumption that system is initially empty. The number of customers in the system is stochastically increasing and distributed in steady state (stationary state) as required. The expressions for the measure of the speed of convergence from transient state to s...
متن کاملAbout the true type of smoothers
We employ the variational formulation and the Euler-Lagrange equations to study the steady-state error in linear non-causal estimators (smoothers). We give a complete description of the steady-state error for inputs that are polynomial in time. We show that the steadystate error regime in a smoother is similar to that in a filter of double the type. This means that the steady-state error in the...
