Summary
An existing boundary integral formulation for steady or unsteady subsonic flow for fixed-wing and rotary-wing applications is being recast into a form in which the wake and/or field influence is coupled into the linear Laplace solver through the boundary conditions. There are a number of advantages in using this approach. For instance, since the wake effect is “seen” as an induced velocity, any methodology that can provide this information may be used. From an engineering point of view, this is desirable for its flexibility and versatility. Furthermore, for transonic flow this formulation does not require a body-fitted field grid. This is of considerable advantage for flows around complex configurations. In addition, this new formulation is essentially based on the concept of velocity decomposition. Therefore, future extension to allow for viscous effects may be accomodated in a fairly straight-forward manner.
