Abstract
A method is presented that combining the Mcclements suspension model with the cylindrical model to solve the complexity of calculating the scattered acoustic pressure around the cylinder, when suspended particles are contained in the water. The scattered acoustic pressure of an infinitely long cylinder in water is derived based on the boundary conditions. Then, the wave number of the particle-containing suspension is calculated by the Mcclements suspension model, which is combined with the scattered acoustic pressure of an infinitely long rigid cylinder in water. The scattered acoustic pressure of an infinitely long rigid cylinder in suspension is obtained. The results show that the content of sediment particles has a greater impact on the distribution of scattered acoustic pressure. The scattered acoustic pressure is more directional with the increase of the content of sand particles, laying a foundation for further research on other target objects in suspension.
