A majority of continuous mining machines employ a water spray system and a machine mounted flooded-bed scrubber to suppress and capture dust during coal mining. These machine mounted dust control systems must be designed to function within the localized face ventilation system at the mining section to control both dust and methane. Spray systems can impede or improve the scrubber effectiveness ...

The present study constitutes a crucial step towards the development of a CAD based intelligent spray quetiching system capable of optimizing the mechanical properties (strength, hardness) of agehardenable aluminum alloys. The quenching of an L-shaped aluminum alloy with multiple, partially overlapping spray nozzles was successfully modeled using the finite element method. Spray heat transfer c...

Until the early 1990s, predominant method of fuel delivery for compression ignition engines was mechanical pump-line-nozzle system. These systems typically consisted a cam-driven pump that would send pressurized to injectors where injection timing fixed according pressure needed overcome spring injector needle. configurations were robust; however, they limited single event per thermodynamic cyc...

A simple atomizing device is presented capable of generating controlled spray by using an electric field either in isothermal and burning conditions. The stability operating range of controlling parameters (e.g. liquid flow rate and applied voltage) is determined. The coupling of atomization and combustion processes is analyzed by measuring, using a PDA system, the drop diameter distribution as...

An adiabatic dry saturated steam compression process with inner evaporative spray cooling in screw compressors for steam heat pump systems is studied. Thermodynamic model and simulation of this variable-mass compression process are devised. Differential equations are formulated and used to calculate the amount of liquid injected and the work to drive the compressor on the basis of simplificatio...

Piroxicam, an anti-inflammatory drug, exhibits poor water solubility and flow properties, poor dissolution and poor wetting. Consequently, the aim of this study was to improve the dissolution of piroxicam. Microparticles containing piroxicam were produced by spray drying, using isopropyl alcohol and water in the ratio of 40:60 v/v as solvent system, and spray chilling technology by melting the ...

Background: The RenuvaTM System is a dietary supplement sold to prevent symptoms of age-related growth hormone decline. Objective: Test the ability of the RenuvaTM System to increase growth hormone (GH) and insulin-like growth factor-1 (IGF-1). Methods: The RenuvaTM System is a two-part dietary supplement to maintain a healthy endocrine system. The “Generator Drink” contains amino acids and nic...

Automated water pump systems are becoming increasingly important as they can regulate pumps based on current data and conditions, reducing energy use waste while ensuring efficient distribution. Research shows that automated have several advantages over traditional manual systems, including increased efficiency, lower consumption, better management, improved performance. However, there also som...
