Air cycle machines were first developed in the 19th century for providing chilling on ships. The technique is a reverse Brayton cycle (the thermodynamic cycle of a gas turbine engine) and is also known as a Bell Coleman cycle or "Air-Standard Refrigeration Cycle".
A compressor map is a chart which shows the performance of a turbomachinery compressor.This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor.
All modern air conditioning systems, even small window package units, are equipped with internal air filters. [citation needed] These are generally of a lightweight gauze-like material, and must be replaced or washed as conditions warrant. For example, a building in a high dust environment, or a home with furry pets, will need to have the ...
The sailing ship Dunedin, the world’s first major refrigerated ship, using the Bell-Coleman process Bell-Coleman refrigerator compressor. Joseph James Coleman FRSE (often referred to simply as J. J. Coleman) (1838–1888) is credited with invention of a mechanical dry-air refrigeration process first used in the sailing ship ‘’Dunedin’’ and sometimes referred to (as a ship type) as ...
Compressible flow (or gas dynamics) is the branch of fluid mechanics that deals with flows having significant changes in fluid density.While all flows are compressible, flows are usually treated as being incompressible when the Mach number (the ratio of the speed of the flow to the speed of sound) is smaller than 0.3 (since the density change due to velocity is about 5% in that case).

Download and install System Mechanic Everyday PC usage can take its toll on computer and PC systems, making them annoyingly slow. System Mechanic, from iolo, is a software suite that secures, optimizes, repairs and fine tunes your computer after five restarts so the system can run faster and at its best.
The G.I. pocket stove is 8 + 1 ⁄ 2 inches (220 mm) high and 4 + 1 ⁄ 2 inches (110 mm) in diameter, and weighs about 3 pounds (1.4 kg). It was designed to burn either leaded or unleaded automobile gasoline (sometimes referred to as "white gasoline" or pure gasoline, without lead or additives).
Here, Mach 4 flow over a pitot probe is observed by schlieren optics in the Penn State Supersonic Wind Tunnel. The flow direction is left-to-right. The flow direction is left-to-right. A supersonic wind tunnel is a wind tunnel that produces supersonic speeds (1.2< M <5) The Mach number and flow are determined by the nozzle geometry.
