The spatial stability of microscopic target droplets used for laser-plasma soft x-ray generation in vacuum is investigated. A long-term drift in drop position is characterized with an ultrafast laser-diode imaging system. The drift is experimentally and theoretically shown to be due to a temperature-induced increase in target-liquid viscosity as a result of evaporation. Finally, the drift is co...

We study phase transitions of small two dimensional Lennard Jones drops via microcanonical molecular dynamics in a broad energy range. We found that the caloric curve can be extended to high energies to comprehend high evaporation rates and highly non-equilibrium phenomena such as multifragmentation. Multifragmentation appears as a constant temperature region in the caloric curve like the solid...

A liquid droplet in contact with a solid surface was simulated by the molecular dynamics method, in order to study the microscopic aspects of the liquid-solid contact phenomena and phase change heat transfer. Measured ‘contact angle’ was well correlated by the depth of the integrated potential of the surface. The layered liquid structure near the surface was also explained with the integrated p...

We interpret lattice data for the equation of state of pure gauge SU(3)c by an evaporation model. At low temperatures gluons are frozen inside the gluon condensate, whose dynamics is described in terms of a dilaton lagrangian. Above the critical temperature quasifree gluons evaporate from the condensate: a first order transition is obtained by minimizing the thermodynamical potential of the sys...

The small hydraulic diameters employed during  ow boiling in compact evaporator passages are becoming more important in diverse applications including electronics cooling and fuel cell evaporators. The high pressure drop characteristics of these passages are particularly important as they alter the  ow and heat transfer, especially in parallel multichannel conŽgurations. The pressure drop osc...

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...

The evaporation heat transfer and pressure drop characteristics of HFC-161 in a horizontal smooth tube with an inside diameter of 9 mm was experimentally investigated. The local heat transfer coefficient and total pressure drop were measured at the heat flux ranging from 15 – 25 kW/m, the mass flux ranging from 100 – 200 kg/(m·s), and the evaporation temperature of 5, 10 °C. The experimental re...
