Noun
/ˌθɜːrməˈdaɪnəmɪk ˈsaɪkl/
A thermodynamic cycle refers to a series of processes that involve the transfer of energy in the form of heat and work, and it usually results in the return of a system to its initial state. It is a fundamental concept in thermodynamics and is used to analyze the performance of heat engines, refrigerators, and heat pumps. The term is commonly used in engineering and physical sciences.
The frequency of use for the term "thermodynamic cycle" is relatively low in everyday conversations but is prevalent in technical and scientific literature. It is primarily utilized in written contexts, such as textbooks, papers, and technical articles.
The efficiency of a thermodynamic cycle can be increased by optimizing the working fluid.
(La eficiencia de un ciclo termodinámico se puede aumentar al optimizar el fluido de trabajo.)
Understanding the thermodynamic cycle is crucial for designing more effective engines.
(Entender el ciclo termodinámico es crucial para diseñar motores más efectivos.)
The Carnot cycle is a classic example of a thermodynamic cycle that operates between two temperature reservoirs.
(El ciclo de Carnot es un ejemplo clásico de un ciclo termodinámico que opera entre dos reservorios de temperatura.)
While "thermodynamic cycle" does not commonly appear in idiomatic expressions, the context of thermodynamics is rich with specific terminologies related to cycles and processes. Here are some relevant concepts and phrases that apply to thermodynamics generally, which can be seen as related extensions.
Thermal equilibrium
A state in which two bodies connected by a permeable barrier do not exchange thermal energy.
"In a thermal equilibrium, no net heat transfer occurs between the two systems."
(En un equilibrio térmico, no se transfieren calores netos entre los dos sistemas.)
Heat engine
A machine that converts thermal energy into mechanical work.
"The steam engine is an example of a heat engine using a thermodynamic cycle."
(La máquina de vapor es un ejemplo de un motor térmico que utiliza un ciclo termodinámico.)
Reversible process
A process that can be reversed without leaving any changes in the surrounding environment.
"An ideal thermodynamic cycle is comprised of reversible processes."
(Un ciclo termodinámico ideal está compuesto por procesos reversibles.)
Entropy change
The quantification of disorder or randomness in a thermodynamic process.
"The entropy change in a thermodynamic cycle helps determine the efficiency of energy conversion."
(El cambio de entropía en un ciclo termodinámico ayuda a determinar la eficiencia de la conversión de energía.)
Adiabatic process
A process in which no heat is transferred to or from the system.
"In an adiabatic process, the internal energy changes due to work done on or by the system."
(En un proceso adiabático, la energía interna cambia debido al trabajo realizado sobre o por el sistema.)
The term "thermodynamic cycle" is derived from the following roots: - "Thermo" originates from the Greek word "therme," meaning heat. - "Dynamic" comes from the Greek "dynamis," meaning power or force. - "Cycle" is derived from the Greek "kyklos," meaning circle or wheel, indicating that the process returns to the starting point.
