La secuencia de eventos termodinámicos en un motor de combustión puede representarse y calcularse en un diagrama idealizado. Idealizado significa aquí que la compresión y expansión de los gases en el cilindro se considera isentrópica, es decir, sin aumento o pérdida de calor. En la práctica, naturalmente es necesario que los cilindros Sean enfriados para que se alcancen pequeños valores máximos de presión y temperatura.

Why LP turbine rotor expansion is more than casing?
In a low-pressure (LP) turbine, the rotor expansion is greater than the casing due to the design and operational conditions of the turbine. The rotor experiences a significant drop in pressure and temperature as steam expands through the turbine stages, resulting in a larger volumetric increase compared to the casing, which is designed to contain the steam flow with minimal expansion. This difference allows for efficient energy extraction from the steam, optimizing the turbine's performance while maintaining structural integrity in the casing. Overall, the rotor's greater expansion accommodates the dynamic changes in steam properties as it moves through the turbine system.
Why LP turbine diaphragm breaks?
Lp turbine diaphragm breaks due to positive pressure inside the condenser because of steam expansion.
What is the difference between isentropic and isenthalpic expansion?
isenthalpic expansion is through PRDS or control valve where entropy changes. Whereas expansion through a steam turbine is isentropic one and enthalpy drops. isentropic expansion is more efficient process as compared to isenthalic one.
What is the significance of isentropic turbine efficiency in the performance of a turbine system?
The isentropic turbine efficiency is important in determining how well a turbine system converts energy from the fluid passing through it into mechanical work. A higher isentropic efficiency means the turbine is more effective at converting energy, resulting in better overall performance of the turbine system.
What is the isentropic efficiency of a turbine and how does it impact the performance of the system?
The isentropic efficiency of a turbine is a measure of how well the turbine converts the energy of the fluid passing through it into mechanical work. A higher isentropic efficiency means that the turbine is more effective at converting energy, resulting in better performance and higher output for the system. Conversely, a lower isentropic efficiency indicates that more energy is lost as heat, leading to reduced performance and efficiency of the system.
What is the significance of turbine isentropic efficiency in the performance of a turbine?
The turbine isentropic efficiency is important because it measures how well a turbine converts the energy in the steam into mechanical work. A higher efficiency means the turbine is more effective at generating power, while a lower efficiency means there is more energy loss. This can impact the overall performance and output of the turbine.
What is the significance of the isentropic efficiency of a turbine in the context of thermodynamics and energy conversion processes?
The isentropic efficiency of a turbine is important in thermodynamics and energy conversion because it measures how well the turbine converts the energy of a fluid into mechanical work without any energy losses due to friction or heat transfer. A higher isentropic efficiency means that the turbine is more effective at converting energy, resulting in better overall performance and energy conservation.
What is the significance of the isentropic efficiency of turbines in the context of thermodynamic processes?

What is reheat factor?
It is the ratio of cumulative heat drop to isentropic heat drop in a multistage steam turbine.

Turbine negative expansion and positive expansion?
Negative expansion in a turbine occurs when the turbine suffers from a loss of power output due to factors like fouling or damage. Positive expansion, on the other hand, would refer to the ideal scenario where a turbine operates efficiently and produces the expected power output.

What is the main isentropic thermodynamic process?
Practically there is no reversible isentropic process but to make the concept easier to be understood, you have to assume the following: * Ideal gas. * no friction losses. * Adiabatic preocess (no heat gain, no heat loss). API 520 part 1 Appendix B assumes that the vapor expansion through a nozzle or a pressure relief valve follows an isentropic path.
