“…In many engineering applications, especially for in-situ measurements, conventional anemometers are more practical than PIV systems. Only one in-situ PIV measurement [84] can be found in all reviewed articles. More portable and easy-to-use PIV systems are crucial for extending the indoor PIV applications.…”

“…6(b). Mortensen et al [84] performed a PIV investigation of the airflow pattern in the microclimate behind furniture placed next to exterior walls. The results indicated that the flow rates behind the furniture would increase with increased distance between the closet and the wall, and even higher airflow rates were seen when the furniture was elevated by legs.…”

Quantifying the airflow field in building room or vehicle cabin indoor space is crucial for creating a thermal comfortable and healthy indoor environment. Airflow field measurement can provide quantitative information of indoor air distribution and local air velocity around occupants or passengers, which has strong relationship with the ventilation effectiveness, the pollutant transportation and the energy conservation in a building or a vehicle. However, the airflow field in indoor environment is normally characterized by high turbulent level and unsteady due to relatively low air velocity from the diffuser, thermal plume of heat source and unsteady perturbation of occupants' behavior. Generally, it is very difficult to conduct accurate and detailed measurement of such a complex turbulent flow field with point-wise anemometry.

“…Cool vertical surfaces, such as windows, induce downward flows, which results in a circular movement of air around the room. A typically observed air movement pattern is the upward flow from radiators or air circulation behind furniture or paintings due to the difference of temperature between the wall and the air [70]. PM is largely transported by the movement of the surrounding air.…”

Fine particulate matter is, on account of its aerodynamic properties and typical composition (especially diesel particulate matter and carbonaceous particles) the particulate pollutant potentially most harmful to cultural heritage, representing an aesthetic issue and an agent of chemical degradation simultaneously. This paper reviews the current knowledge of the life-cycle of fine particulates, focussing on diesel particulate matter from emission to deposition, including its aesthetic and chemical consequences, and draws attention to some imbalances in the current state of research. The currently available measurements are biased towards coarse dust, and information on the consequences of particle deposition is largely restricted to the outdoor environment. More evidence on the chemical effects of the most common types of fine particulate matter in typical indoor materials is needed to enable risk assessment for indoor collections.

“…The air gap that is created thereby serves as a capillary break, which protects the wood from capillary transported moisture in the brick wall. A proper air circulation through the air gap cannot be ensured unless it is kept adequately accessible for air movement (Mortensen et al 2008). Common supporting systems of panels are constructed of densely placed crossbars (i.e.…”

The multiphysics modeling of heat and moisture induced stress and strain of historic building materials and artefacts

2013

The basic structure of historic sites and their associated interior artefacts can be damaged or even destroyed by climate change. The evaluation of combined heat and moisture induced stress and strain (HMSS) can predict possible damage-related processes. In this paper, the development of one-and two-dimensional HMSS models of building materials and artefacts in COMSOL Multiphysics Version 4, a commercial finite element software, is presented. The validation of the numerical models is revealed using analytical, numerical and experimental solutions. As a result, the HMSS model was shown to be an adequate predictive tool to determine possible damage-related processes in building assemblies and artefacts.
