Is Stirling cycle possible?

Thermodynamically, the ideal Stirling cycle consists of an isothermal compression, constant volume heat addition, isothermal expansion, and constant volume heat rejection. The Stirling cycle, without regeneration, is rather inefficient, but with effective regeneration, the system efficiency can be high.

Do Stirling engines run silently?

The Stirling engine is usually quiet because the combustion is not explosive and it can use almost any combustible fuel and any source of heat, including biomass. This type of CHP has rather low electrical efficiency, about 25-30\% when natural gas is used as a fuel.

Is the Stirling engine reversible?

The cycle is reversible, meaning that if supplied with mechanical power, it can function as a heat pump for heating or cooling, and even for cryogenic cooling. The cycle is defined as a closed regenerative cycle with a gaseous working fluid. This also categorizes the engine device as an external heat engine.

Is a Stirling engine adiabatic?

In the previous section we considered an ideal Stirling engine model in which the compression and expansion spaces were maintained at the respective cooler and heater temperatures. However both the compression and expansion spaces are adiabatic, in which no heat is transferred to the surroundings.

Is Stirling cycle reversible?

The cycle is reversible, meaning that if supplied with mechanical power, it can function as a heat pump for heating or cooling, and even for cryogenic cooling. The cycle is defined as a closed regenerative cycle with a gaseous working fluid.

Why is the Stirling cycle reversible?

What is a Stirling engine?

The Stirling engine is an external combustion engine. This characteristic differentiates it from other types of engines such as the Otto engine or the diesel engine which are internal combustion engines. Both engines operate according to the Otto cycle and the diesel cycle respectively. The Stirling cycle is reversible.

What are the steps in the Stirling cycle?

1. Process 1-2 (Isothermal compression) 2.2. 2. Process 2-3 (Constant volume cooling) 2.3. 3. Process 3-4 (Isothermal expansion) 2.4. 4. Process 4-1 (Constant volume heating) Stirling cycle was devised by Stirling, which consists of two isothermal processes and two constant volume processes.

Is the Stirling cycle elliptical or elliptical?

In real applications of the Stirling cycles (e.g. Stirling engines) this cycle is quasi-elliptical. The idealized Stirling cycle consists of four thermodynamic processes acting on the working fluid (See diagram to right): 1-2 Isothermal heat addition (expansion). 2-3 Isochoric heat removal (constant volume).

What is the difference between the Otto cycle and Stirling cycle?

Both engines operate according to the Otto cycle and the diesel cycle respectively. The Stirling cycle is reversible. This cycle can be used by generators to obtain mechanical energy from the application of heat and a cold source (a heat pump). You can also use this cycle to obtain thermal (heat) or cold energy by applying mechanical energy.
