This study carried out a simplified baffle filter shape on the over range (OTR) used in general kitchen. In order to improve filter’s efficiency, simulation was performed using ANSYS FLUENT and COMSOL Multiphysics, wind tunnel test apparatus manufactured minimize error rate of dust collection efficiency experiment. case physical filter, it confirmed through theoretical review that is collected ...

Mist-assisted film cooling has exhibited great potential for efficient of a turbine blade. Trench structures can significantly affect the performance air, while their impact on adhesion characteristics droplets and thus mist-assisted is unclear. This work highlights combination these two aspects by exploring improvement trenched holes with shaped lips using three-dimensional computations. The r...

Aiming at the problem where current engineering wake model does not describe wind speed distribution of in complex terrain farm completely, based on three-dimensional full (3DJGF model), this paper proposed a that can predict entire region farm, taking into account Coanda effect, shear and subsidence under Gaussian terrain. Two types Doppler lidar were used to conduct field experiments, inflow ...

Precise prediction of ventilation flow is essential to create a comfortable, economical, and healthy indoor environment. In the past three decades, computational fluid dynamics (CFD) method has been used more often, it now one primary methods for studying building ventilation. The most common CFD RANS simulation because low cost resources good accuracy. This paper presents numerical investigati...
