Plenum chamber. A plenum chamber
Plenum chamber
A plenum chamber is a pressurised housing containing a gas or fluid (typically air) at positive pressure (pressure higher than surroundings). One function of the plenum is to equalise pressure for more even distribution, because of irregular supply or demand. A plenum chamber can also work as an acoustic silencer device.

What is a take off in a duct system?
Take-offs help to redirect air around your home. In a 2-way duct system, the supply plenum usually sits on top of the AH/furnace or A/C coil in an upflow configuration. When the take-offs are straight, they form a right angle which can result in poor airflow. Instead of straight upflow, a flared one can work better.

Etymology
The term "plenum" was coined in the 1670s, derived from Latin adjective plenus ("filled, full"). The usage originates from classical theories of physics and the notion that " nature abhors a vacuum ". These gave rise to the notion of 17th century 'plenum' as the opposite of vacuum, and all things "being either Plenum or Vacuum". [2]
Supercharging
Supercharged piston engines typically use many cylinders arranged in-line and one or two superchargers. Superchargers deliver air at a relatively constant rate, while cylinders demand it in a varying manner, as the valves open and as piston speed varies through the stroke.
Norton Classic
The Norton Classic was a motorcycle whose air-cooled twin-rotor Wankel engine was developed by David Garside at BSA. [3] [4] Wankel engines run very hot, so Garside gave this air-cooled motor additional interior air-cooling. Air was drawn through a forward-facing filter situated to provide a ram air effect.
Hovercraft
Practical hovercraft use a peripheral skirt system, where the air from the lift fans is routed to a narrow slot around the edge of the hull, and bound by a flexible skirt.
Nuclear Waste burning reactor rods

Answered by CarsGuide
The plenum chamber is a chamber located in front of the windshield, where air pressure is above atmospheric. It provides a volume of air which is drawn into the car from the chamber through the heater, air-conditioner or vents.
Overview
A plenum chamber is a pressurised housing containing a fluid (typically air) at positive pressure. One of its functions is to equalise pressure for more even distribution, compensating for irregular supply or demand. It is typically relatively large in volume and thus has relatively low velocity compared to the system's other components. In wind tunnels, rockets, and many flow applications, it is a chamber upstream on the fluid flow where the fluid initially resides (approxi…

Supercharging
Supercharged piston engines typically use many cylinders arranged in-line and one or two superchargers. Superchargers deliver air at a relatively constant rate, while cylinders demand it in a varying manner, as the valves open and as piston speed varies through the stroke. Simple direct ducting would give problems where the nearest cylinders received more airflow. The pulsating demand from the cylinders would also show problems of either pressure waves in the duct, or a …

The Norton Classic was a motorcycle whose air-cooled twin-rotor Wankel engine was developed by David Garside at BSA. Wankel engines run very hot, so Garside gave this air-cooled motor additional interior air-cooling. Air was drawn through a forward-facing filter situated to provide a ram aireffect. 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. The plenum (which dou…
Hovercraft
Practical hovercraft use a peripheral skirt system, where the air from the lift fans is routed to a narrow slot around the edge of the hull, and bound by a flexible skirt. Distribution of this air from the fans to the periphery is through a large-volume plenum chamber, so as to provide even distribution of airflow without sensitivity to the length of the direct path.
Nuclear Waste burning reactor rods
Molten salts consisting of chlorinated nuclear waste are contained in atomic fission reactor rods this Alvin M. Weinberg et al design has a liquid fuel instead of a solid fuel. The gas plenum is above the fuel and below a diving bell style vent for the reaction products. 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.
