Model Penjalaran Gelombang Akustik Pada Saluran Bunyi Di Bawah Permukaan Laut (Deep Sound Channel Axis) Menggunakan Metode Euler-Cromer

Deep sound channel axis is the sound channel below sea level in which the sound velocity gradient has minimum value. Computational modeling of the Deep sound channel axis has been done by dividing the sea into layers with a constant sound velocity, in each layer the Snellius equation is converted to an iteration equation by applying the Euler-Cromer equation to simulate deflection of sound wave. The purpose the modeling is to determine the maximum angle of propagation of sound waves on the Deep sound channel axis. Modeling was done by simulating the emission of sound waves at a depth of 854m with a sound velocity of 1487,53ms-1. The length of the ray r and the angle θ are determined for modeling with constant gradients and not constant gradients. The results obtained are the maximum angle of sound wave propagation of 0,2838 rad for constant gradients and 0,1302 rad for not constant gradients. The propagation of sound waves at a larger r with the same iteration provides a wider range of sound wave propagation. The percentage of computational error results for analytics for the length of 1m to 4m rays is 0,0461%, 0,2325%, 0,6181% and 1,1418% and range of propagation is 11000m, 22000m, 33000m, and 44000m respectively. Distance of wave propagation as the length of rays increase, but the percentage of error is greater. Therefore smaller wave length is more accurate even though the distance of propagation is shorter.
