Influence of initial turbulence intensity on the heat and moisture transfer through a recirculated air curtain
<p>"An air curtain is a directed jet of air separating a controlled space from an environment of different temperature and humidity. This investigation describes the development and verification of an eddy viscosity model which accounts for the influence of the initial turbulence intensity on the …

Investigation into the design and optimisation of multideck refrigerated display cases
… Further enhancements such as the reduction of air overspill from the case would also influence the aisle temperatures and therefore the comfort levels in the store. This research project uses the technique of computational fluid dynamics (CFD) to investigate the contemporary design of a …

Monitoring and Control of Coal Dust Exposure Using Low-Cost PM Sensors and Computational Fluid Dynamics
… prone to elevated coal dust levels, the canopy air curtain (CAC) was developed to protect then high coal dust concentrations. However, the current generation CAC only provides a 46% coal dust reduction efficiency leaving room for improvement. Insufficient coal dust monitors in mines make it …

Effects of Dust Controls and Dust Sources on Respirable Coal Mine Dust Characteristics
… controls (i.e., a dry and wet scrubber, canopy air curtain, and a wet versus dry dust collection boxes). In the second and third studies, preserved samples from these prior NIOSH dust control studies were re-analyzed and evaluated to understand their effects on dust characteristics. Results …
