ANALYSIS OF JET-CROSSFLOW INTERACTIONS WITH APPLICATION TO SHIP BOW THRUSTERS

An analytical model of a jet injected normally from a flat plate into a uniform crossing flow was formulated to provide a simplified method of predicting the interference effects arising from the complex flow fields induced by ship bow thrusters. This model was an extension of previous work based upon a description of the jet as a series of distributed vortices. The analysis takes into account the position of the effective source of the jet and the blockage due to the presence of the jet in the crossflow. For representative jet-to-crossflow velocity ratios, the flow field and pressure distributions were calculated utilizing different combinations of effective source position and blockage. The accuracy of the model was evaluated by comparison with the available experimental data. Although good agreement was achieved for large portions of the interaction field, several regions were identified requiring further analytical description. (Author)
