“…Accordingly the authors have tested different turbulence and radiation models available in the commercial computational fluid dynamic codes, on a three dimensional model, and the results have been compared to those of the PIV measurements [20]. The simulations have been carried out on a 3D model with the same geometry, materials and boundary conditions as the experimental unit of [19]. The results show that the ventilation produced by buoyancy is enhanced by the cavity height and incident radiation.…”

“…As shown in the study of Sanjuan et al [19], complex air flows are generated inside the naturally ventilated cavity by the existence of open joints. For this reason, the use of advanced fluid measurements and simulation techniques are necessary.…”

“…Sanjuan et al [19] carried out a study to present a Particle Image Velocimetry (PIV) technique to measure the velocity field inside the air cavity of an OJVF model in laboratory conditions. The study focuses in a generic geometry and investigates the turbulent natural convection inside the ventilated cavity under radiation conditions.…”

a b s t r a c tThis article presents the state of the knowledge on the thermal analysis of double skin facades with integrated photovoltaic (PV) panels called the Building Integrated Photovoltaics (BIPV) in terms of the published studies carried out on these systems. The idea of integration of the PV panels by replacing building elements, increase the prospects of the renewable energy systems. Taking also into account the need to use more renewable energy systems in buildings, the investigation of the BIPV systems to improve their performance is of a great importance. The literature studies are separated into experimental and theoretical for naturally ventilated systems and mechanically ventilated with external means e.g. fan use. It is concluded that most researchers studied the systems with mechanical ventilation rather than the systems with natural ventilation because the latter are more complex in terms of the air flow behaviour in the air duct. Additionally, various researchers proposed Nu number correlations and convective heat transfer correlation under several assumptions and conditions every time, for different range or Ra number which are presented and compared in this paper.

“…In this case, PIV is a more suitable technique for its non-intrusive property. Sanjuan et al [56,57] used PIV to measure the velocity field inside the air cavity of an Open Joint Ventilated Facades (OJVF) model, as shown in Fig. 3(a).…”

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.
