Abstract

A transient multiphase CFD analysis using the VOF method coupled with a 6DOF solver is used to model the water impact of a launch vehicle spent stage with floats. Overset Mesh motion technique was used to model the 6DOF based motion of the body. The stability of the spent stage water impact solution was studied by varying implicit mesh update features. The water impact of spent stage with different diameter floats was also studied. The CFD model is validated for the water impact of a wedge which was available in the literature. The CFD predicted results for the wedge case are within the 5% of the measurement in the prediction of maximum penetration depth.
