Revisiting Endo-reversible Carnot engine: Extending the Yvon engine [PDF]

open access: yesarXiv
A famous paper [Am. J. Phys. 43, 22 (1975)] unveiled the efficiency at maximum power (EMP) of the endo-reversible Carnot heat engine, now commonly referred to as the Curzon-Ahlborn (CA) engine, pioneering finite-time thermodynamics. Historically, despite the significance of the CA engine, similar findings had emerged at an earlier time, such as the ...

Support of Study on Engineering Technology from Physics and Mathematics [PDF]

open access: yesarXiv, 2008
An approach that provides students with an ability to transfer learning in physics and mathematics to the engineering-technology courses through e-teaching and e-learning process is proposed. E-modules of courses in mathematics, physics, computer systems technology, and electrical and telecommunications engineering technology have been developed. These

Some investigations in design of low cost variable compression ratio two stroke petrol engine [PDF]

open access: yesarXiv, 2012
Historically two stroke engine petrol engines find wide applications in construction of two wheelers worldwide, however due to stringent environmental laws enforced universally; these engines are fading in numbers. In spite of the tight norms, internationally these engines are still used in agriculture, gensets etc.

Loop Stirling engines [PDF]

open access: yesarXiv
The Stirling engine is a type of heat engine known as its high efficiency. It is applied in solar thermal power, cogeneration, space nuclear power, and other fields. Although there are many different types of Stirling engines, their airflow paths are always linear.
