Although many fluidized systems are not vertically oriented, little research has been done on fluidization within inclined channels. The fluidization of the gravitational force and the tensile force may be substantially opposing in the vertical system. The theory of gravitational field fluidization, which is related to industrial fluidization processes like coal gasification, iron ore reduction, and catalytic cracking and calls for the use of standing tubes or angled risers, has to be developed in order to encompass various orientations. Without underlying theories, engineers must rely on vertical fluidization equations to build these sloping systems. A significant barrier to improving the design and optimization of new solid circulation systems is the tendency of fluidization. Based on historical developments and theoretical progress, the study presents an overview of recent advancements of liquid-solid fluidized beds in inclined columns. The fluidized bed is investigated as a whole by looking at the governing factors.

In practice there are many processes that have complicated and complex character. Most often, these are dynamic systems with a large number of variable parameters, which significantly complicates their study, analysis and prediction. For their study most commonly used simulations that allow you to gain knowledge of their systemic nature. In these systems include and the thermodynamic systems where, due to a change of the many influencing parameters: temperature, pressure, velocity, fluid flow rate, various physical processes take place. For their study is widely used computer simulations to help predict the behaviour of systems under various conditions. Simulations are closely related to direct geometric modelling to enable to interactive design research and rapid model creation, allowing engineers to experiment with design ideas and immediately see the result of their changes. As an object of the simulation is most often fluid, structural and thermal simulation applications, which are used both for research and for innovative practical solutions in manufacturing enterprises. Computer simulations allow to predict the behaviour of certain processes in a real environment through virtual testing of CAD models. The main stages contain a methodical sequence, which includes the construction of a mathematical model, its numerical solution and processing of the obtained results. The main equations that make up the mathematical models are the balance equations of mass, momentum and energy, which determine the distribution of velocities, pressures, densities, temperatures and other control parameters. For modelling of flows of liquids and gases for industrial tasks, turbulence, heat transfer and chemical reactions, etc. are taken into account. In the practice, a large number of software solutions to simulate the processes occurring in thermal and fluid flows offered by many manufacturing companies are used. The aim of the present study is to analyse the possibilities of the software products used in practice to simulate the behaviour of dynamic fluid flows under certain initial conditions. Based on the analysis and the formulated conclusions, the choice of a software module for specific thermal research and construction of a geometric model of the studied objects through which numerical (CFD) simulations will be performed using different models, research in different modes of work, as well as the validation of the created methodologies, will be substantiated.
