Abstract The impact of droplets on non-fixed spherical particles placed a plane polymethyl methacrylate (PMMA) substrate is investigated. This interaction highly abstracted level high-pressure spray cleaning process. Water in diameter range between 0.68 and $$1.66\,{\mathrm{mm}}$$ 1.66 m...

Droplet microfluidics, in which micro-droplets serve as individual reactors, has enabled a range of high-throughput biochemical processes.[1] The talk will start with our recent application on using droplets to identify bacteria, specifically methane-metabolizing bacteria, for increasing the efficiency of generation of bioplastics.[2] This work, along with emerging applications to screen very l...

The metal transfer behavior of gas arc welding in a pure argon shielding was evaluated through experiments using standard solid wire and metal-cored wire. investigation conducted observation techniques based on recording images by high-speed camera equipped with laser assistance bandpass filters range currents. It observed that the mode became streaming when current increased Meanwhile, wire, d...

the objective of this research is to develop an accurate numerical method to be used in showing the deformation of a liquid fuel droplet in a convective field. to simultaneously solve the internal liquid droplet flow field as well as the external gas phase flow field, a nonstaggered rectangular grid system without any coordinate transformation is used. transition from the gas field to the liqui...

The potential for nanofuels as one of the clean sources of energy on account of its enhanced combustion performance coupled with low emissions has been established. Considering the importance of the fuel evaporation phase in the entire combustion process, this work presents an attempt at applying the steady state analysis equations to nanofuel experimental data obtained from the li...

An experimental study of the post-impact spreading of liquid droplets on dry horizontal substrates is presented in this paper. The drop spreading and recoil behaviors are captured using a high-speed digital video camera at 2000 frames per second. To ascertain the effects of liquid interfacial and viscous properties, experiments were conducted with five liquids (water, ethylene glycol, propylene...

The spreading of aqueous dispersions of trisiloxane with various polyethylene oxide chain length surfactant solutions over hydrophobic surfaces is considered from experimental point of view. It is shown that the transfer of surfactant molecules from the droplet onto the hydrophobic surface changes the wetting characteristics in front of the drop making them useful in waterbased coatings for pla...

BACKGROUND The Influenza A H1N1 virus can be transmitted via direct, indirect, and airborne route to non-infected subjects when an infected patient coughs, which expels a number of different sized droplets to the surrounding environment as an aerosol. The objective of the current study was to characterize the human cough aerosol pattern with the aim of developing a standard human cough bioaeros...
