Definition
Each of the simulated air standard cycles comprises four processes. The left hand part of the animation
shows any movement of the piston and associated transfers of heat and work. The right hand part shows the corresponding
progress on the process part.
Where it occurs
The following are illustrated:
- isochoric (constant volume) processes are part of the air standard Otto, Diesel and Stirling cycles;
- an isobaric (constant pressure) expansion is part of the air standard Diesel cycle;
- isothermal (constant temperature) processes are part of air standard Carnot and Stirling cycles;
- isentropic (constant entropy) processes are part of air standard Carnot, Otto, Diesel and Stirling cycles.
Special features
The webpage presents:
- the movement of the piston (if any);
- a colour coding for the working gas in the cylinder, from blue (cold) to red (hot);
- arrows showing heat transfers to or from the reservoirs (for the Stirling Engine, some heat is transferred horizontally to/ from a regenerator);
- arrows showing work transfer to or from the surroundings (viz a flywheel);
- the corresponding location on the pV or Ts diagram - the colour coding of the marker indicates temperature;
- text above and below the canvas indicating type of process, energy conversion and end temperature.
