The history of the scientific and technical school of our scientific and engineering group dates back to 1930!

August 21, 1930 at the Leningrad Polytechnic Institute by the name of M. I. Kalinin the Department of compressor engineering was created. The world’s first specialized Department of compressors and compressor technology.

The first chair was an outstanding scientist of power engineering Konstantin Ivanovich Strakhovich!

During the years of existence of Department from 1930 to 2019, 145 candidate’s and 16 doctoral thesis were written and defended at the Department.

The scientific and engineering group «Compressor, vacuum, refrigeration equipment and gas transportation and processing systems» was created by the department’s specialists specifically to perform work for industrial customers. After the department was closed in 2019, the group continued to work as an interuniversity group, interacting with leading universities in St. Petersburg and continuing to interact with industrial partners.

Константин Иванович Страхович - первый заведующий кафедрой компрессоростроения ЛПИ

Konstantin Ivanovich Strakhovich — the first head of the compressor equipment department.

Konstantin Pavlovich Seleznev — founder of the scientific school of compressor engineering in LPI-SPbPU. . from 1960 to 1989 he was the head of the LPI compressor engineering Department – the country compressor engineering leading scientific center. In 1973 – 1983 he was the rector of the Institute. After 1989 he was a Professor — scientific director of research groups related to the topic of centrifugal compressors of high and ultrahigh pressure.

Chairman of the petroleum Ministry NTS and USSR chemical industry, Chairman of the compressor engineering section.

The Scientific and Engineering Group has an extensive in-house database to verify the results of CFD modeling and simulation of gas transmission facilities and systems.

In addition, the scientific and engineering group has its own methods of gas dynamic design of flow parts of centrifugal compressors, including its own methods of designing highly efficient axial impellers, methods for creating digital twins of gas infrastructure facilities, methods for modeling heat exchange processes, methods for coupled acoustic and strength calculations of reciprocating compressors and their piping, methods for calculating rotor dynamics, methods for calculating gas dynamics, etc. the strengths of compressors of various types.

All this allows us to carry out compressor designs of various types with high accuracy and develop dynamic modeling programs for facilities and gas systems in the oil and gas industry.
