Future Developments

The extremely wide range of hydrocyclones available and separation applications for which they can be used assures their future role in particle classification. However, significant obstacles remain before they can be used to replace more efficient methods for fine classification purposes, such as centrifuges. Classification inefficiencies, in particular the large bypass, limit their application. The potential of very small diameter hydrocyclones for sub-micron particle separation, especially in multistage configuration, is enormous, if these inefficiencies can be reduced.

Hydrocyclone modelling has advanced significantly with the use of CFD. Empirical hydrocyclone models are convenient ways of describing experimental data but do not enhance the understanding of the separation and CFD models will play a greater role in hydrocyclone simulation. Nonintrusive measurement techniques such as laser Doppler anem-ometry (LDA), laser Doppler velocimetry (LDV) and tomography have indicated the source of hydrocyclone inefficiencies. With increased resolution and combined with CFD models, this will improve hydrocyclone unit design.

Hydrocyclone operations will benefit from novel methods for monitoring which are currently being developed. Industrial tomography is becoming affordable, and the potential of visual and sonic techniques has been illustrated.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
