N2 - A computational study is conducted to evaluate the performance of an autonomous submarine to operate in the liquid hydrocarbon seas of Titan, Saturn’s largest moon, to simulate the flow around the submarine and offer a prediction for the power requirements. Computational Fluid Dynamics is used for deeply submerged and freesurface conditions. In the deeply submerged case, mesh-based code is utilized to show velocity and pressure contours, and to calculate the total drag force. Specific cases of the submarine navigating the free-surface are analyzed using a particle-based method which yields relevant information about wave generation and fluid forces. The goal is to find the optimal navigation technique when the submarine is operating on the freesurface and deeply submerged for different values of sinkage and depths in two of Titan’s largest seas, Kraken and Ligeia Mare.
