In this study, a quantitative relationship between material properties, process settings and screw feeding responses of high-throughput feeder was established via multivariate models (PLS). Thirteen divergent powders were selected characterized for 44 property descriptors. During volumetric trials, the maximum feed capacity (FCCmax), relative standard deviation on (RSDFCmax), short term variabi...

In order to further improve the mixing performance of device, structure agitator was optimized, and effects diameter pitch on solid-liquid suspension characteristics were analyzed by single factor method. Multiple reference frame (MRF), computational fluid dynamics, Euler multiphase flow model standard K- ε turbulence used investigate effect height from bottom particles in studied. The results ...

Older adults frequently suffer from sleep disturbances. In addition, with increasing age such disturbances may accompany mild cognitive changes that are symptomatic of a range of neurodegenerative conditions. There is increasing evidence that sleep may represent a prodromal symptom, risk factor or agitator of further decline in cognitive functioning of the older adult. Current research is focus...

The work on the quality improvement of fuel oil using acid treatment was carried out. The improvement of the fuel oil was done using sulphuric acid to remove contaminants. Sulphuric acid at different concentrations were mixed with the oil and kept at 45°C for four hours in the agitator vessel to allow reaction to take place. Acidic sludge was then drained off from the agitator and the oil was n...

In this study, a coil heat exchanger with an ice storage system is analyzed by theoretical analysis, numerical analysis, and experimental analysis. The dynamic characteristics of ice thickness variation is studied by means of unstable heat conduction theory in cylindrical coordinates, and the change rule of the ice layer thickness is obtained. The computational fluid dynamics method is employed...

• Dynamics of driven ATR characterised experimentally and numerically. Optical acoustic methods agree well with LBM numerical model. Mixing regime depends strongly on applied amplitude, a , agitation frequency, f . power number increases re as 2 3 above critical value. Agitator tube induces fluid wakes, motion closely coupled to velocity field. This study investigates the dynamics novel, oscill...
