Introduction
I am interested in mathematical modelling and optical diagnostics of multiphase flows, particularly in sprays and droplets and their extension towards designing sustainable energy and biological systems. I focus on problems involving heating, evaporation, reactive flow and breakup of multi-component fuel droplets and sprays.

Article
Full-text available
The results of new experimental and theoretical investigations of puffing and micro-explosion of rapeseed oil/water droplets placed in ethanol and propane/butane mixture flames are presented. It is pointed out that time to puffing/micro-explosion increases with increasing initial droplet radii in both flames. This time is always shorter for a propa...
Article
The paper is focused on detailed experimental investigation of puffing and micro-explosions in composite water/rapeseed oil droplets in the presence of lignite and bituminous coal micro-particles in water. Gas temperature was measured using a high speed National Instruments 9219 for data collection and an S-type thermocouple. Video recording of dro...
Article
A new approach to modelling puffing and micro-explosion in composite water/fuel droplets is proposed. This approach is based on the assumption previously made that a spherical water sub-droplet is located in the centre of a spherical fuel (n-dodecane) droplet. The heating of a fuel droplet is described by the heat conduction equation with the Robin...
Article
A new analytical solution to the one-dimensional transient heat conduction equation in a composite spherically symmetric water-fuel emulsion droplet, suspended in a hot gas, is obtained. The Robin boundary condition at the surface of a droplet and conditions at the fuel-water interface are used. A water sub-droplet is assumed to be located at the c...
Article
Full-text available
A new simple model for the puffing/micro-explosion of water-fuel emulsion droplets is suggested. The model is based on the assumption that a spherical water sub-droplet is located in the centre of a larger fuel droplet. The fuel is approximated by n-dodecane. The fuel droplet surface temperature is assumed to be fixed, and fuel evaporation is ignor...
Article
Full-text available
Water-in-diesel emulsions potentially favor the occurrence of micro-explosions when exposed to elevated temperatures, thereby improving the mixing of fuels with the ambient gas. The distributions and sizes of both spray and dispersed water droplets have a significant effect on puffing and micro-explosion behavior. Although the injection pressure is...

This paper aims on synthesis and characterization of Aluminium LM6 composites, discontinuously reinforced with iron oxide (γ-Fe2O3) particles and MWCNTs under different compositions using stir casting method. An investigation of carried out to determine physical, mechanical and electromagnetic properties of LM6 composites. Alumina particles were pr...
