Plenum chamber

A plenum chamber is a pressurised housing containing a fluid (typically air) at positive pressure.

The Norton Classic was a motorcycle whose air-cooled twin-rotor Wankel engine was developed by David Garside at BSA.

This air passed through the interior of the rotors and then into a large pressed-steel plenum before entering the combustion chambers via twin carburettors.

[5] The plenum (which doubled as the bike's semi-monocoque frame) enabled the transfer of much of the heat to the surrounding atmosphere.

[citation needed] Molten salts consisting of chlorinated nuclear waste are contained in atomic fission reactor rods.

This allows for convection currents and fluid flow eliminating the possibility for gas products to build up and rupture as in a light water reactor.
