Thermodynamics Practice Test: Gas Power Cycles — Flashcards

Gas Power Cycles topics include: Carnot cycle, stirling circle, brayton cycle, diesel cycle, otto cycle and aircraft propulsion.

Here are some basics about gas power cycles:

Carnot cycle: The most basic gas power cycle, which acts as a benchmark for all engine cycles. The efficiency of every engine cycle is compared against the Carnot Cycle.
Gas-generator cycle: Also called the open cycle, this cycle takes a small amount of fuel and oxidizer from the main flow to feed a burner called a gas generator. The hot gas from the generator passes through a turbine to generate power for the pumps that send propellants to the combustion chamber.
Combined cycle: This power concept combines gas turbine power cycles with steam turbine power cycles. This is achieved by using the large amount of heat in the Gas Turbine (GT) exhaust gas as energy input for the Steam Bottoming Cycle (SBC).
Dual cycle: This gas power cycle has five processes: adiabatic expansion, constant volume heat addition, constant pressure heat addition, adiabatic expansion, and constant volume heat rejection.
