A plug flow transient advection model for water and pipe temperature based on a sliding 1-D grid has been developed and validated for a single pipe, then extended to also model recirculating systems. Heat losses in a pumped system may be reduced using a timer so the system can cool over...
in paper manufacturing). A domestic use of an air cyclone can be seen in Dyson™ vacuum cleaners, which separate dust particles from air. The use of hydrocyclones is also known in central heating systems to remove air bubbles. Hydrocyclones have not previously been applied to shower systems....
The design, theory and characteristics of combustors in which the reactants (or the combustion air alone) are preheated using heat recycled from beyond the flame zone, without mixing the two streams, are reviewed. There is a great variety of such systems, based on a combustor in between th...
