Thermodynamical Analysis of the Transmagistral Pipelines using Computer Software

Increasing the efficiency and durability of the piston compressors, pumps, internal combustion engines, etc. directly depends on the correct calculations and designing of these elements. Using ANSYS software, simulation and stress analysis are performed on the basis of the 405GP15/70 and ARIEL heavy-duty balanced opposed piston compressors used in the Caspian Sea - Black Sea Region, providing numerical validation of thermal and structural behavior under operational conditions. Investigation of complex problems with respect to stresses, and thermodynamics phenomena in the piston machines, and oil and gas pipelines gives the opportunity to solve the problems of increasing the durability of these machines and pipelines. Increasing the reliability and durability of piston machines therefore meets the current industrial demand for minimizing environmental impacts during the exploitation and transportation of oil and gas resources. The novelty is characterized by new theoretical methods for the determination of forces of gas pressure in cylinders of reciprocating machines taking into account the wear processes and the clearances in kinematic couples of crank-piston mechanisms. The reliability of the received scientific results is provided with the correctness of the statement of tasks and decisions on the basis of laws of physics, mechanics and thermodynamics. The results of the investigation are generalized for any piston machines used in the oil and gas industry. The results of the investigation can be useful for the design and exploitation of transregional pipelines and environmental problems.
