Due to the increasing energy cost, efficiency of industrial dryer as energy-intensive processes should be improved. The designer optimize design parameters drying equipment achieve minimum consumption. SST k-ω turbulence model is used simulate a real geometry for applications. For optimization impinging round jet, specific consumption set objective function minimized. jet surface distance, spac...

Machine learning is a promising technique for angle-of-arrival (AOA) estimation of waves impinging sensor array. However, the majority methods proposed so far only consider known, fixed number waves, i.e., sources (NOS). This paper proposes machine-learning-based estimator designed case when NOS variable and hence unknown priori. The comprises framework single-label classifiers. Each classifier...

Frequent premature failure of the ISIS spallation neutron source target prompted investigation previously unexplored aqueous slurry erosion response pure tantalum (Ta) with an overarching aim to improve service life target; hence, reducing disposal radioactive waste. Understanding such Ta is highly significant many other applications as nuclear and chemical processing. In this study, powder-met...

heating and sudden cooling are among the most important processes affecting temper quality in the production period of tempered auto glass. in this study, heat transfer characteristics and cooling times during the sudden cooling process of tempered glass production have been experimentally investigated. flat glass with dimensions of 50x50x4 mm has been heated up to 680 ºc in the furnace and was...

Superhydrophobic surfaces are abundant in nature. Several surfaces such as wings of butterfly, legs of water strider, feet of gecko and the lotus leaf show extreme water repellence behaviour. Self-cleaning, stain-free fabrics, spill-resistant protective wears, drag reduction in micro-fluidic devices etc. are few applications of superhydrophobic surfaces. In order to design robust superhydrophob...

The sticking coefficient for D(2)O impinging on crystalline D(2)O ice was determined for incident translational energies between 0.3 and 0.7 eV and for H(2)O on crystalline H(2)O ice at 0.3 eV. These experiments were done using directed molecular beams, allowing for precise control of the incident angle and energy. Experiments were also performed to measure the intensity and energy of the scatt...

In this paper a simulation to maximize the global solar radiation on a sloped collecting surface was applied to typical latitudes in the area of southern Italy, to calculate the optimum tilt angle of solar panels on building structures or large photovoltaic power plants located in that geographical area. Indeed, the area of southern Italy and in particular Sicily and Calabria are the top of Eur...

Many workers perform their daily activities outdoors and many anatomical body sites are exposed to UV radiation. The effects of solar radiation on human health depend on the amount and type of radiation impinging on the body. This paper aims to investigate and analyse the diurnal UV radiation exposure at typical anatomical site for farm workers. The diurnal distribution in solar UV exposure at ...

A novel parallel laminar micromixer with a two-dimensional staggered Dean Vortex micromixer is optimized and fabricated in our study. Dean vortices induced by centrifugal forces in curved rectangular channels cause fluids to produce secondary flows. The split-and-recombination (SAR) structures of the flow channels and the impinging effects result in the reduction of the diffusion distance of tw...
