Abstract:

We compared WHOI Cable simulations with results from other studies involving towed arrays Ablow and Schecter, 1983. The towed array results were incorporated into a manuscript about the WHOI Cable numerical scheme, which was submitted this year and is now in press Gobat and Grosenbaugh, 2005. We are preparing a new manuscript on simulation results of towed vehicles undergoing circular maneuvers and the comparison with pervious studies Chapman, 1984. We continue to work on incorporating VIVA software into WHOI Cable so that we can calculate the normal drag coefficient as a function of instantaneous vibration amplitude. We performed a comparative study on the use of thruster control mounted on a towed vehicle undergoing two-dimensional maneuvers. These results were published in Grosenbaugh and Bowen 2005. We presented a workshop on the use of the WHOI Cable software with emphasis on towed sonar arrays to engineers at SACLANT Undersea Research Centre in October 2004.
