Computational optimization of gas compressor stations: MINLP models versus continuous reformulations

Mathematical Methods of Operations Research, 2016
When considering cost-optimal operation of gas transport networks, compressor stations play the most important role. Proper modeling of these stations leads to nonconvex mixed-integer nonlinear optimization problems.

Influence of compressible medium on the operation of a reciprocating compressor

MATEC Web of Conferences, 2018
A reciprocating compressor is a volumetric machine. Consequently, the motion of gas in communications always is of non-stationary or pulsating character. The diagram of oscillatory processes in communications is complex because a number of factors affect
