“…Comparing the results obtained from AirKaz.org and the simulated results (uncontrolled), it can be seen from Table 2 that the contribution of the power plants is at an average of 35%, that is, 38.98 µg/m 3 of the total PM 2.5 concentration per hour, which is about eight times the permissible PM 2.5 concentration for a city, according to the WHO [26][27][28][29].…”

According to the World Health Organization, Kazakhstan is one of the most polluted countries in the world. PM2.5, a major air pollutant, is six times higher than the recommended value of 5 mg/m3. The government has implemented measures to reduce air pollution, such as introducing green energy-powered buses for public transportation, but the results have not been sufficient. Therefore, it is necessary to investigate the sources of PM2.5. This study involved simulating the Combined Heat and Power Plants (CHPPs) emissions in Almaty using AERMOD and WRF for two weeks in January 2021. Two scenarios were performed: controlled and uncontrolled. The results showed that if the control mechanism of the CHPP functions at maximum efficiency, the impact of the CHPP emissions on the total emission concentration will be negligible, which is about 6% on average. However, for uncontrolled CHPPs, the emissions will contribute from 30% to 39% on average to the total PM2.5 concentration when compared with data from US Embassy monitoring stations and public air quality monitoring network, which use Pms5003 PM2.5 sensors.

“…Participation of the pollution generated by the aircraft in the ongoing situation of environment makes propulsion designers focus on the low-emission propulsions by introducing new configurations of the available technologies toward increasing efficiencies and reducing the pollutions. Meanwhile, modeling the performance of the new concepts including the impact of flight condition on the engine performance 1 and effects of the propulsion working condition on its emission 2,3 plays an important role to improve such concepts and speed up approaching the best available configuration for them.…”

This two-parts article introduces a novel hybrid propulsion system based on the DEA compressor. The system encompasses a Pulse Detonation TurboDEA as the master engine that supplies several full-electric ancillary thrusters called DEAThruster. The system, called the propulsion set, can be categorized as a distributed propulsion system based on the design mission and number of ancillary thrusters. Part B of this article explains the performance sizing of the propulsion set designed in part A. Evaluating the performance of the propulsion, computer programs are written for all major components of the both master engine and ancillary thruster. The intake, compressor, detonation process, diffusers, axial turbine, and exit nozzle are modeled under certain flight conditions, and their performances are revealed and analyzed. The flight conditions are considered from the static condition at the sea level up to flight Mach number 5 at an altitude of 20,000 m. The performance of the propulsion set is also compared with some aircraft propulsions modeled by similar studies in all important aspects.
