Master’s Degree Show on Engineering Systems and Urban Economy Was Held at SPbGASU

Current issues related to water use and disposal, heat and gas supply and ventilation, electric power and electrical engineering, geodesy, land management and cadastral registration were discussed at the 3rd regional scientific and practical conference – Master’s degree show "Engineering Systems and Urban Economy", which took place at SPbGASU on March 17-19.

The conference was attended by representatives of SPbGASU, Saint Petersburg Mining University, and Saint Petersburg State University.

“I hope that the discussion platform organized at SPbGASU will enable all participants to showcase their research findings, bring up innovative ideas for discussion, and share the production experience. I am sure that the exchange of theoretical and practical knowledge between leading scientists and practitioners on important issues in the field of engineering systems and urban economy will help to find effective solutions to existing problems”, said SPbGASU Vice Rector for Science Irina Drozdova at the opening of the conference.

Kirill Angelov's presentation: standard graphs of wastewater flow rate fluctuations

The first day of the conference was devoted to the topics of water use and ecology. Master's student Kirill Angelov, under the guidance of Svetlana Ignatchik, DSc, Professor of the SPbGASU Department of Water Use and Ecology, examined the impact of uneven wastewater inflow on the operation of urban wastewater treatment plants. The treatment systems that are available now do not take into account this irregularity, which can lead to insufficient quality of cleaning, and this, in its turn, may result in various sanitary and environmental problems. According to the author, this problem hasn’t been studied enough, so the student plans to analyse the existing methods of modelling and calculations of sewage treatment facilities and propose a solution taking into consideration the existing research outputs in this area.

At the session on electric power and electrical engineering held on March 18, Yegor Pilipenko spoke about the advantages of mini hydropower plants. These are small-scale power plants that generate a relatively small amount of electricity and most often do not require the construction of dams, creation of reservoirs, or the flooding of surrounding areas. The advantages of small-scale hydropower plants are environmental friendliness, compactness, minimal economic investment. Since the structures do not require a high water pressure, they can be operated in the channels of small rivers and streams, as part of pumped-storage power plants, in a sewer current. The student proposed to combine standard designs of water towers with existing structures of mini pumped- storage power plants, which will ultimately allow to build an energy-efficient, environmentally friendly installation for the accumulation of electrical energy in large volumes. The author believes that the potential for using small-scale hydropower plants is almost unlimited. Their wider application will save natural resources.

Presentation by Kirill Kopylov: mathematical model of a vehicle fire

At the conference session devoted to heat and gas supply and ventilation, which took place on the same day, Master’s student Kirill Kopylov presented his research study “Modelling a car fire at the entrance to an underground parking lot”. A prerequisite for the study was designing a smoke control system in underground parking lots on horizontal sections with a slope (ramps). In the reference literature, ramps are divided into insulated (covered, having walls) and non-insulated (completely open). The author offered an illustrative example to assess the relevance of fire safety requirements in smoke exhaust systems in an insulated ramp. He created a mathematical model of the combustion process as the car enters an underground parking lot. The obtained indicators of the distribution of the gas-air mixture and the nature of the overflow can be used for optimal placement of smoke exhaust valves, and selection of the best design solutions for smoke ventilation systems.

At the session on geodesy, land management and cadastres, organized on March 19, Master’s student Natalya Shapovalova analysed the elite residential real estate market in St. Petersburg for state cadastral valuation using residential premises as an example. The supply in the elite residential real estate market of St. Petersburg in 2020 amounted to 121.7 thousand square meters, which is 26% less than in the previous year. At the same time, the demand in the first half of 2020 amounted to 27.2 thousand square meters and exceeded the same indicator in 2019 by 21%. The weighted average offer price at the end of June 2020 was 360,000 rubles/m2, which is 7% higher than in 2019. The author concluded that the main pricing factors for elite residential real estate in the Northern capital are the influence of the city centre, proximity to water, parks and architectural monuments, the prestige of the area and the type of the building, apartment size, interior finishing, security of the adjacent territory. During the pandemic, potential buyers preferred 2-4-room apartments in small-size residential buildings (up to 50 apartments).

“A distinctive feature of the conference is engaging Master’s degree students to present the results of their research activities. As a rule, interesting ideas and ways of solving urgent problems are born in the course of our events”, noted Svyatoslav Fedorov, PhD, Associate Professor of the Department of Water Use and Ecology.
