CFD - Calculation of a Turning Lathe

In this case a calculation of the air flow below the off-take of a turning lathe for machining glass resulted in that there was not sufficient protection for an operating person working below this off-take.

Accordingly, we had to redesign the off-take based on our calculation in order to improve the exhausting effect without aspiring additional air volume.

Area of Computation:

The space modelled for the simulation comprises the yellow turning lathe for machining glass, the light blue hood and the dark blue tubes of the ventilation system.

 

 

The picture shows the yellow turning lathe for machining glass, the light blue hood and a small brown burner in the center.

The air flow to be calculated is turbulent, non-isothermal and influenced by ascending forces.

The green parts represent our constructional improvements:

Cover plates have been added to the outer area of the previous hood and a new smaller hood has been installed in the inside.

Glass particles which are formed in the area around the burner move on flow lines, which are illustrated by different colours depending on the respective velocity.

The picture illustrates the vectors of the flow velocity in different colours depending on the magnitude within a sectional plane of the hood.
