Computational fluid dynamics (CFD) is the method to visualize how air or liquid flows — as well as how the air or liquid effects in-stream objects.

CFD is based on the Navier-Stokes equations. These equations describe how the velocity, pressure, temperature, and density of a moving fluid are related.

## Case 1 – Turbo compressor

Objective:

To determine the total and static pressures, as well as the gas temperature at the compressor outlet and at each stage of the process. Calculate unit efficiency and the compression ratio

Solution:

A flow channel of the compressor with a bezel-free diffuser is created. A grid of finite elements of the flow channel and cochlea is constructed. The model of turbulence is chosen. The corresponding boundary conditions are given. Total and static pressures as well as the temperature of the gas at the outlet of the impeller, diffuser and cochlea are calculated. The efficiency of the machine and the degree of compression are determined.

## Case 2 – Cyclone

Objective:

Determine the coefficient of hydraulic resistance of a cyclone unit

Solution:

A 3D model of the cyclone is constructed. A grid of finite elements is generated in the calculated flow region. The initial and boundary conditions are determined. Pressure and velocity fields are obtained depending on the air flow through the cyclone. Current airflow lines are designed. The coefficient of hydraulic resistance of the cyclone is calculated.

## Case 3 – Orifice plate

Objective:

Determine the hydraulic resistance of the orifice plate (normal diaphragm)

Solution:

A 3D model of a pipeline section with a normal diaphragm is constructed. A grid of finite elements is generated in the calculated flow region. The initial and boundary conditions are determined. Pressure and velocity fields are obtained depending on the air flow rate. The hydraulic resistance of a normal diaphragm is determined.
