Simple design criteria and efficiency of hydrodynamic vortex separators
Vortex separators are locally applied for waste water treatment in different systems - from storm waste water sewerage to water treatment in fish ponds. However, the methods for separator design presented in the literature are questionable. The paper presents two simple and functional criteria that were employed to construct a laboratory test stand. The test results gave positive feed back on the efficiency of vortex separators.

Determination of Mechanical Energy Loss in Steady Flow by Means of Dissipation Power
When systems of simple geometry like pipes or regular channels are considered, the mechan- ical energy loss of the fluid flow can be expressed by local and longitudinal empirical energy loss coefficients. However, in the case of large spatially distributed objects, there are no simple approaches to this task. In practice, general recommendations addressing different types of objects are used, but they usually provide very coarse...

Dimensioning of vortex storm overflows
Vortex flow control can be made as a rotational chamber, where the centrifugal force is a supporting factor. The paper presents a simplified, but experimentally verified, method of such device designing.
