“…A theoretical simulation of the contaminant's distribution and chemical interactions in the atmosphere during fuel burning at Ekibastuz SDPP-1 has been presented. A real-life example of a thermal power plant was used to model the dispersion of NO, NO2, CO, and products NO2, HNO3, CO2 waiting for chemical interaction with oxygen (Ekibastuz SDPP -1) [19]. The effects of different emission scenarios on NOx, SO2, PM total, and CO concentrations were simulated using the AERMOD air quality model.…”

Air pollution is a worldwide and a local issue caused by energy generation. It refers to global warming deterioration in human environmental health and local-global sustainability. This review provides information on the generation and consumption of energy with their air pollution mixture of many pollutants; gases, liquids and particles. These pollutants have become one of the leading environmental hazards to human and planet health. The components of pollutants that result from burning fossil fuels (oil and gas) and coal have been studied, such as sulfur dioxide, carbon dioxide, nitrogen oxides and particles. Both sulfur dioxide and nitrogen oxides interact with water to produce acid rain. Both gas and oil-fired thermal power plants emission today and in the future might be transformed to work on renewable energy sources. The results stated that gas-fired power plants are more generally faster efficient, less pollution than oil and coal power plants. A complete assessment of exhaust gas treatment was conducted. Carbon dioxide capture, desulfurization, denitrification, and particle collection were all successful as treatment control mechanisms. So, previous studies presented some methods for reducing nitrogen oxides and sulfur oxides through water injection and exhaust gas recycling. The addition of nano-additives in diesel emulsion fuel (W/D) has recently been shown to increase the characteristics and performance of the fuel while reducing the quantity of emitted hydrogen chloride (HC) and carbon monoxide (CO). It was determined that the best nano-additives for W/D were Aluminum Oxide (Al2O3), copper(ii) oxide, magnesium oxide (MgO), manganese oxide (MnO), and zinc oxide (ZnO), among others (E10).

The spread of the novel coronavirus disease (COVID-19) continues to show that geographic barriers alone cannot contain the virus. Asymptomatic carriers play a critical role in the nature of this virus, which is rapidly escalating into a global pandemic. Asymptomatic carriers can inadvertently transmit the virus through the air stream. Many diseases can infect human bodies with tiny droplets or particles that carry various viruses and bacteria that are generated by the respiratory system of infected patients. This article presents the numerical results of the spread of droplets or particles in a room. The proposed numerical model in this work takes into account the sedimentation of particles or droplets under the action of gravitational sedimentation and transport in the room during the process of breathing and sneezing or coughing. Three different cases are numerically investigated taking into account normal breathing and coughing or sneezing, respectively, and three different rates of particle ejection from the mouth are considered. Navier–Stokes equations for incompressible flows were used to describe three-dimensional air flow inside ventilated rooms. The influence of ventilation rate on social distancing is also computationally investigated. It was found that particles can move up to 5 m with a decrease in concentration in the direction of the air flow. The conclusions made in this work show that, given the environmental conditions, the two meter social distance recommended by WHO is insufficient.

“…All the model equations used for the simulation and description have been referred from peer-reviewed publications ( Spalart, 1997 , Menter, 1994 ; Menter and Kuntz, 2003; Jones and Launder, 1972 ). The SST k-ω model was used owing to its ability to demonstrate a precise depiction of the indoor airflow ( Stamou and Katsiris, 2006 , Zhang et al, 2009 , Hussain and Oosthuizen, 2012 , Hussain et al, 2012 ; Issakhov et al, 2021; Issakhov et al, 2020 ).…”
