The quality of the environment within buildings is a topic of major importance for human health. Indoor air pollutants include formaldehyde, volatile organic compounds (VOCs), particulate matter, ozone, and biological contaminants. Those hazardous outdoor air pollutions have severely affected indoor air quality, threatening the health of billions of people, due to the dominant exposure for humans. Therefore, indoor air quality should be maintained at a suitable level through technologies to provide fresh air, to purify the indoor air and to control the pollution. With increase of building tightness, the ventilation plays a more critical role than in the past in maintaining an acceptable indoor environment. The ventilation modes include natural, mechanical, and their hybrid type, which creates different airflow patterns (such as trajectory, impingement, separation, circulation, reattachment, buoyancy, vortices etc) and airflow field (temperature, velocity and pressure), and finally affects the indoor air quality. Besides, mechanical and electronic filtration are effective for removing suspended particles, adsorption is useful to retain gaseous contaminants, and Photo-oxidation is effective to reduce the indoor organic contaminants. The progress in these technologies is helpful to improve the indoor air quality and human living environment. 

This Special Issue will be coordinated by the Fluid dynamics and Materials Processing, which is an excellent EI and ESCI journal focusing on materials processing and fluid dynamics. The target of the present special issue is to present the leading edge of indoor air flow and pollutant in residential buildings and the corresponding pollutant control technologies. Original and review research papers on the following topics are welcomed but not limited to: 
1) Ventilation forms and removal of indoor pollutant; 
2) Air distribution and indoor air flow patterns; 
3) Transportation of particles (PM2.5 and PM10); 
4) Generation and distribution of volatile organic compounds (VOCs); 
5) Pollutant problem in high-density crowds;
6) Purification of gaseous contaminants;
7) Numerical methods on studying gas-particle flow;
8) Sensor technology over harmful gases;
9) Smart building technology in monitoring and controlling indoor pollutant.

    Design and Optimization of a Hybrid Energy System for Decentralized Heating

    Ling Cheng, Bingqing Guo, Kecheng Li
    FDMP-Fluid Dynamics & Materials Processing, Vol.17, No.1, pp. 49-70, 2021, DOI:10.32604/fdmp.2021.011062

    Abstract The performances of a hybrid energy system for decentralized heating are investigated. The proposed energy system consists of a solar collector, an air-source heat pump, a gas-fired boiler and a hot water tank. A mathematical model is developed to predict the operating characteristics of the system. The simulation results are compared with experimental data. Such a comparison indicates that the model accuracy is sufficient. The influence of the flat plate solar collector area on the economic and energy efficiency of such system is also evaluated through numerical simulations. Finally, this system is optimized using the method of orthogonal design. The… More >

    Convection-Diffusion Model for Radon Migration in a Three-Dimensional Confined Space in Turbulent Conditions

    Shengyang Feng, Dongbo Xiong, Guojie Chen, Yu Cui, Puxin Chen
    FDMP-Fluid Dynamics & Materials Processing, Vol.16, No.3, pp. 651-663, 2020, DOI:10.32604/fdmp.2020.07981
    (This article belongs to this Special Issue: The Progress in Building Indoor Air Quality: Indoor Airflow and Pollutant Control)
    Abstract Convection and diffusion are the main factors affecting radon migration. In this paper, a coupled diffusion-convection radon migration model is presented taking into account turbulence effects. In particular, the migration of radon is simulated in the framework of the k-ε turbulence model. The model equations are solved in a complex 3D domain by the finite element method (FEM). Special attention is paid to the case study about radon migration in an abandoned air defense shelter (AADS). The results show that air convection in a confined space has a great influence on the radon migration and the radon concentration is inversely… More >

    Study on Buildings CCHP System Based on SOFC

    Bin Zhang, Yongzhen Wang, Jiaqing Zheng, Dan Liu
    FDMP-Fluid Dynamics & Materials Processing, Vol.16, No.3, pp. 665-674, 2020, DOI:10.32604/fdmp.2020.09314

    Abstract The relationship among the working temperature, pressure and current density of a Solid oxide fuel cell (SOFC) and its output power and efficiency are analyzed in the framework of a theoretical model able to provide, among other things, the volt ampere characteristic curve. In particular, following the principle of temperature matching and cascade utilization, we consider a gas turbine (GT) and a LiBr absorption chiller to recycle the high-grade exhaust heat produced by the considered SOFC. This distributed total energy system is set up with the intent to meet typical needs of buildings for cooling, heating and power (CCHP). The… More >

    An Experimental Investigation about the Levels of PM2.5 and Formaldehyde Pollutants inside an Office

    Xiangli Wang, Peiyong Ni
    FDMP-Fluid Dynamics & Materials Processing, Vol.16, No.2, pp. 237-243, 2020, DOI:10.32604/fdmp.2020.09469
    (This article belongs to this Special Issue: The Progress in Building Indoor Air Quality: Indoor Airflow and Pollutant Control)
    Abstract PM2.5 and formaldehyde are two main indoor pollutants potentially threatening the health of human beings. In this paper, the concentrations of PM2.5 and formaldehyde inside an office were measured under different conditions. The effects of temperature on the formaldehyde originating from the decoration materials, including flooring, gypsum powder, joint mixture and corestock, were also assessed. The results show that window ventilation can produce the same PM2.5 purification as an air cleaner. The concentration of formaldehyde released from the decoration materials is highly correlated to the indoor temperature, but it is not significantly influenced by humidity. In particular, the percentage of… More >
