PIV experimental study of airflow structures in a multi-slot ventilation enclosure with opposed jets
نویسندگان
چکیده
The airflow structure of enclosure directly affects the spread COVID-19 and is also closely related to indoor air quality, thermal comfort personnel, building energy consumption. Although a large number studies on field have been conducted under mixing displacement ventilation with single inlet in rectangular rooms. However, best authors knowledge, only limited dealt structures multi-slot opposed jets. Therefore, this paper uses PIV study velocity entropy unstable jets isothermal non-isothermal conditions. And presents due collision form two large-scale eddies, being unstable. In region without supply inlets exhaust outlets, vortex formed field, resulting high information flow field. plume suppresses increases small-scale structure.

The scouring process at downstream of the hydraulic structures is a complex phenomenon and many parameters affecting its amount. Failure to control this phenomenon causes damages to the dam and its associated hydraulic structures. In this research, the scouring caused by the combination of jets outlet from a gated spillway was investigated experimentally and the combination of jets adjacent to ...
