نویسندگان
چکیده
With the help of FLUENT software, flow characteristics fine particles in upper air supply room with different parameters were studied. The particle trajectory model was established to calculate concentration distribution room, and optimal working area personnel researched reduce impact on human health. By calculating field under four parameters, operating conditions obtained by comparative analysis, that is, temperature 20°C speed 3m/s, which provided a theoretical basis for setting future.

Study on Air Flow Characteristics in Cylinders of a Four-Valve Engine with Different Lifts of Valves
A 1arge-scale tumble rather than swirl would exist in cylinders in the case of two valves’ opening in a fourvalve engine. A strong swirl is generated when one valve is closed, yet the flow capacity is less than that of two valves being opened. In order to change it, different lifts of valves (DLV) present are achieved. In the case of using different lifts of two intake valves, both tumble and s...
متن کاملAir flow and particle control with different ventilation systems in a classroom.
Most ventilation and air conditioning systems are designed without much concern about how settling particles behave in ventilation air flows. For displacement ventilation systems, designers normally assume that all pollutants follow the buoyant air flow into an upper zone, where they are evacuated. This is, however, not always true. Previous studies show that high concentrations of settling res...

Operation Theatre (OT) is the most important area where precise controlled on indoor air quality is required because it is directly related to patient health and its recovery period. This work aims to study and visualize the airflow distribution of conventional flat air diffuser ventilation system and newly designed angular air ventilation system in OT. Angular Air Distribution (AAD) system is ...
متن کاملEffect of Blade Design Parameters on Air Flow through an Axial Fan
The objective of this paper is the numerical study of the flow through an axial fan and examining the effects of blade design parameters on the performance of the fan. The axial fan is extensively used for cooling of the electronic devices and servers. Simulation of the three-dimensional incompressible turbulent flow was conducted by numerical solution of the (RANS) equations for a model. The S...
متن کاملEffect of Particle Clusters on Turbulence Modulations in Liquid Flow Laden with Fine Solid Particles
Studies on particle distributions and interactions between the particles and the liquid turbulence are extremely significant and can help to improve efficiency of industrial processes and final product quality. In this paper, the particle distribution and the particle–turbulence interaction in the solid–liquid flow were investigated in detail by a numerical method. The governing equations of th...
