Many chemical reactions are carried out using stirred tanks, and the efficiency of such systems depends on the quality of mixing, which has been a subject of research for many years. For solid–liquid mixing, traditionally the research efforts were geared towards determining mixing features such as off-bottom solid suspension using experimental techniques. In a few studies that focused on the de...

Ventilation airflow in buildings is paramount important for creating comfortable environment with acceptable indoor air quality by regulating indoor air parameters, such as air temperature, relative humidity, air speed, and concentrations of chemical species in the air. Airflow inside naturally ventilated dairy (NVD) building is highly variable because of the direct effect of outside weather an...

The integration of building Energy Simulation (ES) and Computational Fluid Dynamics (CFD) programs eliminates many assumptions employed in the separate applications, resulting in more accurate predictions of building performance. This paper discusses the methods used to determine convective heat transfer on interior surfaces of building envelope, which is the key linkage between ES with CFD pro...

Computational fluid dynamic (CFD) analysis of the thermal flow in the combustion chamber of a solid waste incinerator provides crucial insight into the incinerator's performance. However, the interrelation of the gas flow with the burning waste has not been adequately treated in many CFD models. A strategy for a combined simulation of the waste combustion and the gas flow in the furnace is intr...

Abstract. In the urban environment, gas and particles impose adverse impacts on health of pedestrians. The conventional computational fluid dynamics (CFD) methods that regard pollutants as passive scalars cannot reproduce formation secondary lead to uncertain prediction. this study, SSH-aerosol, a modular box model simulates evolution gas, primary aerosols, is coupled with CFD software, OpenFOA...

nowadays distillation is recognized as one of the economical and the most trustable separation methods in chemical, petroleum, gas and petrochemical industries. it is almost used as a first and the most applicable choice in separation methods. in this article the effect of inlet downcomer on the hydrodynamics of industrial sieve tray has been elaborated. the study was carried out by using a 3-d...
