Adding a force at a specific point.
Hello,
I am an engineering student and am new to SU2 and CFD in general. I am trying to add a surface force on an airfoil to simulate the suction of a plasma actuator. I want to be able to alter the velocity field at a specific point on the surface of the airfoil. In order to do so, what files would I need to change? Is there a specific source file that would let me do something like this? I am lost. Thank you for your help! |

Are you running Euler or Navier-Stokes? Best, Francisco |
Francisco,
I am using Euler. Thank you, Chris |

Thanks Chris, As you know, the boundary condition for Euler problems is a slip boundary condition, so in practice it is not possible to modify the velocity (normal to the surface). In that case my recommendation is to use the inlet boundary condition % % Inlet boundary marker(s) with the following formats (NONE = no marker) % Total Conditions: (inlet marker, total temp, total pressure, flow_direction_x, % flow_direction_y, flow_direction_z, ... ) where flow_direction is % a unit vector. % Mass Flow: (inlet marker, density, velocity magnitude, flow_direction_x, % flow_direction_y, flow_direction_z, ... ) where flow_direction is % a unit vector. MARKER_INLET= ( NONE ) Another possibility is to use a Navier-Stokes solution, in that situation you can specify a velocity on the solid surface different from 0. Best Regards, Francisco |
