| Summary: | Analysis and design of airfoil are one of the most important processes in the design of
aerospace products. To be able analyze the flow around airfoil, Because of cost and time
reason, a simple computational method is developed, Viscous-Inviscid Interaction.
VII method is a method that divides the fluid domain into two parts, that is viscous
domain and inviscid domain. Solutions of the viscous domain in the airfoil surface are
computed by using integral boundary-layer equation. While solutions of the inviscid
domain outside of the viscous domain are computed by using Laplace equation.
In this research, the writer using Panel method to solve inviscid flow around an airfoil.
While the method used to discretize the system of differential equations of boundary
layer is Discontinuous Galerkin that good for solving hyperbolic differential equation. In
this research, Fully Simultaneous interaction is also applied where velocity distribution
and boundary layer parameters could be solved simultaneously to solve the separation
problems of flow around an airfoil.
The use of Fully Simultaneous interaction is still limited locally in each panel and
shows that the singularity problem has been successfully overcome although it still cannot
provide a smooth solutions of boundary layer and velocity.
