Fluidlrigid body interaction in complex industrial flows D. ~bouri', A. parry1 & A. ~arndouni~ 1 Schlumberger - Riboud Product Center, Clamart, France 2 University of La Rochelle, LEPTAB, La Rochelle, France Abstract Fluid-mechanism interactions occur in a wide range of flow meter categories including turbine and positive displacement systems as well as many flow control devices. This paper outlines computational methods for calculating the dynamic interaction between moving parts and the flow in a flow meter system. The method allows coupling of phenomena without need for access to the source codes and is thus suitable for use with commercially available codes. Two methods are presented; one with an explicit integration of the equations of motion of the mechanism and the other with implicit integration. Both methods rely on a Navier-Stokes equation solver for the fluid flow. The more computationally expensive implicit method is recommended for mathematically stiff mechanisms such as piston mo
