Mathematical models for simulation of layer hydrodynamics of a ship fluidized bed boiler

Fluidized bed boilers have been widely used for many years in energetics but their application in shipbuilding has been incidental. The hydrodynamics of a fluidized bed is a complicated issue. If the swaying of a ship on a sea wave is taken into account, this issue will be further complicated. The choice of an appropriate mathematical model is important from the viewpoint of building computer models for the simulation of a fluidized bed during disruptions that result from the ship swaying on sea waves. Fluidization is a two-phase flow process, which is described by many models such as the homogeneous-slip model or heterogeneous-slide model. The most popular models that show two-phase gas-solid or fluid-solid flow are the Euler-Euler and Euler-Lagrange models. The paper presents models that describe a ship’s fluidized bed.
