Performance of Curzon-Ahlborn engine along with its engine speed and compression ratio
We evaluated the ideal limits of performance (power and efficiency) of heat engines operated with external heat sources along with their engine speed and compression ratio, using the method of adjoint equations based on variational principle. It is known
