An Efficient Euler Method on Non-Moving Cartesian Grids with Boundary-Layer Correction for Wing Flutter Simulations

چکیده
This paper presents an efficient Euler method on Cartesian grids coupled with an integral Boundary-Layer method. The unsteady Euler equations are solved using cell-centered finite volume method by the implicit-explicit dual-time stepping scheme. The wall boundary conditions on the wing are implemented on the wing chord plane by first order approximation so that non-moving Cartesian grids can be used. A two-dimensional integral boundarylayer solver is coupled with the three-dimensional unsteady Cartesian Euler solver in each spanwise cross-section in a quasi-steady manner. This method is very efficient and shown to yield very good results for steady, unsteady flows and flutter simulations of airplane wings.

Calculations of Unsteady Flow and Flutter by an Euler and Integral Boundary-Layer Method on Cartesian Grids
This paper presents an Euler and boundary-layer method capable of unsteady flow and aeroelastic simulations. An integral boundary-layer solver is coupled with an Euler solver in a “semi-inverse” manner. For the inviscid part, approximate wall boundaryconditions are implemented on non-moving mean chord positions, whereas the full nonlinear Euler equation is solved in the field for accurate resol...

We describe a method to solve the compressible time-dependent Euler equations using Cartesian grids for domains involving xed or moving geometries. We describe the concept of a mirror ow extrapolation of a given solution over a reeecting wall which may be curved or moving at a xed or varying speed. We use this mirror ow to develop a Cartesian grid method to treat the cells along a reeecting bou...
متن کاملTransonic Flutter Analysis of an Airfoil with Approximate Boundary Method
Numerical simulation of aircraft’s flutter is rather expensive and time-consuming. In order to save expense and calculating time, we apply first-order approximate conditions to solve the unsteady transonic Euler equations coupled with aeroelastic equations. Assuming that the airfoil is thin and undergoes small deformation, we implement wall boundary conditions on nonmoving mean wall positions. ...

This study examines the use of stationary Cartesian mesh for steady and unsteady flow computations. The surface boundary conditions are imposed by reflected points. A cloud of nodes in the vicinity of the surface is used to get a weighted average of the flow properties via a gridless least-squares technique. If the displacement of the moving surface from the original position is typically small...
